[0029] Figure 2 FIG. 1 is a flow chart of a method for monitoring operating consumables for engineering cost control according to an embodiment of the present application. Figure 2 As shown, the method comprises the following steps:

[0030] Step S201, obtaining multiple operation centers, wherein the operation center is a collection of multiple operations responsible for completing the manufacture of a specific product, and the operation is a process in the production process of a coal mine project;

[0031] Specifically, in the context of coal mining engineering or the broader manufacturing industry, an operation center can be regarded as a unit that integrates multiple production steps or processes that work together to complete part or all of the production process of a specific product or service. The existence of an operation center helps to optimize the production process and improve production efficiency and management efficiency. The operation center does not exist in isolation, but is composed of multiple "operations", which are an indispensable part of the production process of coal mining engineering. Together, they constitute the necessary steps to complete the manufacture of a specific product (in coal mining engineering, it may be a product or intermediate product in a certain link such as coal mining, processing, and transportation). These operations are carried out in an orderly manner under the unified management and coordination of the operation center to ensure the smooth and efficient production process.

[0032] Step S202, obtaining consumption information of the plurality of the operation centers, wherein the consumption information is the type, quantity and unit price of resources consumed by the operation centers for pre-implementing operations;

[0033] Specifically, as an organizational unit in the production process, the activities (i.e., operations) of the operation center consume various resources, such as manpower, material resources, and financial resources. Before the actual execution of the operation, the consumption that may be generated by the operation center is predicted or estimated. The consumption information specifically includes three dimensions: the type, quantity, and unit price of the resource.

[0034] Types of resources: refers to the different types of resources used by the operation center in the process of performing operations. In coal mining projects, this may include human resources (such as miners, technicians), material resources (such as equipment, tools, fuel), financial resources (such as purchasing raw materials, paying wages, etc.) and other indirect resources (such as water, electricity, gas, etc.).

[0035] Quantity: refers to the specific amount of each resource consumed. This is one of the key factors in evaluating resource consumption and cost.

[0036] Unit price: refers to the unit price of each resource.

[0037] Step S203, determining the operation cost according to the consumption information of the plurality of operation centers, and allocating the operation cost to each of the operation centers;

[0038] Specifically, detailed information such as the type, quantity, and unit price of resources consumed by each operation center during the execution of the operation is collected. Based on the collected consumption information, the operation cost of each operation center is calculated. This usually involves multiplying the consumption quantity of each resource by its unit price, and then adding the costs of all resources to obtain the total operation cost of the operation center. After calculating the operation cost of each operation center, these costs are averaged or allocated to each operation center according to certain allocation criteria (such as operation volume, operation time, operation complexity, etc.).

[0039] Specifically, several allocation methods are listed below:

[0040] Activity Driver Allocation Method: Activity drivers refer to the factors that drive the activity, such as production batches, product quantity, machine hours, etc. The activity cost is allocated to each activity center based on the amount of activity drivers consumed by each activity center.

[0041] For example, a production operation center uses machine hours as the operation driver. The center incurred a total operation cost of 100,000 yuan this month, and the machine ran for 2,000 hours. The machine in another operation center ran for 1,000 hours. According to the operation driver allocation method, the first operation center should be allocated 66,667 yuan (100,000 yuan*2,000 hours / 3,000 hours), and the second operation center should be allocated 33,333 yuan.

[0042] Cost ratio allocation method: allocates costs based on the proportion of each operation center in the total operation cost. Usually, this proportion is determined based on the resource consumption or output of each operation center.

[0043] For example, if the cost ratios of two operation centers are 60% and 40% respectively, and the total operation cost is 100,000 yuan, then the first operation center is allocated 60,000 yuan and the second operation center is allocated 40,000 yuan.

[0044] Direct tracing method description: For costs that can be directly traced back to a specific operation center, they are directly allocated to that operation center. This method is suitable for cost items that are directly related to a specific operation center.

[0045] For example, if the depreciation cost of special equipment in a certain operation center is RMB 5,000 per month, this cost can be directly traced back to the operation center without the need to be allocated through other means.

[0046] Composite allocation method: Combine multiple allocation methods, and use multiple allocation standards to make comprehensive allocations based on the characteristics and cost nature of each operation center. This method is usually used in complex production environments and can more accurately reflect the cost situation of each operation center.

[0047] For example, a company may first allocate part of the operating costs to each operating center based on machine hours, and then further allocate the remaining costs to specific products based on product quantity or production batches.

[0048] Step S204, sending the consumption information of the plurality of operation centers and the operation costs of the plurality of operation centers to a target terminal.

[0049] Specifically, after calculating the consumption information and operation cost of the operation center, these data need to be transmitted to a specific recipient, namely the target terminal. The target terminal can be any device or system that can receive and process these data, such as a computer, server, mobile device or a specific management software platform.

[0050] Through this embodiment, the engineering construction process of a coal mine can be decomposed into several independent operation centers, and the consumption and operation costs of each operation center can be clearly calculated. This allows for more refined monitoring of the cost of engineering consumables. After sending it to the target terminal, the staff can promptly understand the cost structure and distribution of consumables of each operation center, thereby solving the problem of the difficulty in effectively monitoring the cost of engineering consumables in coal mines in the prior art.

[0051] Specifically, with the widespread application of technologies such as informatization, the Internet of Things, mobile applications, and big data, the solution of this application provides an effective solution for the cost control of operating consumables in coal mine engineering.

[0052] The solution for intelligent monitoring of operating consumables for engineering cost control provided in this application is an important means of cost control of coal mine engineering consumables. It follows the principle of "top-down decomposition and bottom-up accounting" through the formulation of material quotas, operation cost method, Internet of Things monitoring, mobile applications and big data analysis, and can more accurately identify, allocate and monitor operating consumables costs.

[0053] Specifically, the monitoring method of operating consumables for engineering cost control proposed in the solution of the present application can realize intelligent monitoring and management of the operating consumables costs of the project in terms of intelligent budget writing, limit warning thresholds, dynamic monitoring of consumables usage, and big data analysis.

[0054] The solution of this application improves the scientificity and accuracy of budget compilation by constructing a material quota database based on historical data and real-time information. By breaking down the construction process into several independent operations through the operation-based cost method and calculating the cost of each operation in detail, more detailed and accurate cost information can be provided, and the cost structure and distribution of each operation link can be clearly understood. The Internet of Things and mobile application technologies are used to achieve real-time monitoring and tracking of consumables use to ensure the authenticity and reliability of the data. Through big data analysis technology, the consumables usage data is deeply mined, and the risk of cost overruns is warned in advance, so as to achieve dynamic adjustment and optimization of consumables costs.

[0055] In the specific implementation process, obtaining multiple operation centers can be achieved through the following steps: obtaining operation information of multiple operations mentioned above, wherein the operation information includes one or more of basic engineering information, engineering operation process information and engineering operation material information, wherein the basic engineering information includes one or more of project name, geographical location, responsible unit and project duration, the engineering operation process information includes one or more of development, excavation, mining, transportation, power supply, ventilation and drainage, and the engineering operation material information includes one or more of support materials, equipment accessories, grease, fasteners and sealing materials; according to the target classification method, based on the operation information, the multiple operations mentioned above are classified to obtain multiple operation centers, wherein the target classification method includes one or more of production process classification, operation scale classification, operation complexity classification, product upstream and downstream relationship classification and product mutual supply relationship classification.

[0056] In this solution, operation information can be collected from multiple operations. According to certain target classification methods (such as production process classification, operation scale classification, operation complexity classification, product upstream and downstream relationship classification, product mutual supply relationship classification, etc.), the collected operation information can be used to classify multiple operations. The operations can be classified according to a certain logic and assigned to different operation centers, which will help coal mining enterprises achieve refined management.

[0057] Specifically, the present solution can manage engineering information, mainly including the management of engineering basic information, engineering operation process information and engineering operation material information.

[0058] Basic project information: It can input, store and manage the basic information of coal mine projects, including project name, geographical location, responsible unit, project duration, etc.

[0059] Engineering operation process information: standard operation procedures for coal mine construction are established according to coal mine construction operation regulations, engineering categories, etc., mainly including: development, tunneling, mining and other production processes, transportation, power supply, ventilation, drainage and other auxiliary processes.

[0060] Engineering operation material information: Consumables for coal mine engineering operations mainly include support materials, equipment accessories, grease, fasteners and sealing materials, etc. The system establishes a classification catalog and detailed information of operating materials.

[0061] Specifically, an activity is a part of the production process, and each activity is a cost accounting object. Conducting activity analysis and identifying the main activities are the basis for the application of activity-based costing.

[0062] According to the operation flow of coal engineering construction, the operation is divided, the main operation is confirmed, and the operation center is divided. The operation is defined in a mixed way, divided into two levels: "top-down" and "bottom-up". The operation center is determined by profession or department (such as coal mining, tunneling, electromechanical, transportation, ventilation, etc.), and each operation center is a cost accounting object.

[0063] Specifically, according to the basic principle of activity-based costing, products consume activities and activities consume resources. When calculating product costs, the focus is on activities. By accounting for activity costs, the process of cost formation and accumulation is tracked to derive the cost of the product.

[0064] The calculation procedure is as follows: 1) Determine the main operations and confirm the operation center; 2) Allocate the collected input costs or resources to the cost pool of each operation center. Each cost pool represents the operations performed by that center. Therefore, the cost driver of this step is to confirm the resource consumption of each cost, which is the resource driver; 3) Allocate the costs of each operation center to the final product according to various cost drivers, mainly operation drivers. According to the establishment of corresponding product libraries for each section, each product can be classified into corresponding operations and operation centers.

[0065] A corresponding resource library is established according to each cost type, and resource accounts are stored in a tree form (cascade). Each resource account can be assigned to one or several operations; each resource account has a time dimension attribute (period); and each resource account can be assigned a period value (target value, actual value).

[0066] Costs are attributed to operations, operations are attributed to operation centers, and finally operations and operation centers are attributed to products, forming product operation costs. Operations have organizational dimension attributes, and costs have time dimension attributes.

[0067] An operation center is a collection of a series of operations responsible for completing a specific product manufacturing function. It is both a cost collection center and a responsibility assessment center. The division of operation centers generally follows the "principle of combining responsibility, power, and interest" and the "principle of measurability and controllability". The division is centered on the "organizational dimension" to facilitate cost accounting, evaluation, and assessment.

[0068] After the job is identified, each job is linked according to the job map method, job flow method, process flow method, and job flow method. Through the collection of "a series of jobs", an operation chain is formed from this to that, from the inside to the outside. It mainly uses the production link as the basis for the association, reflecting the "value chain".

[0069] Specifically, according to the operation cost calculation procedure and the characteristics of A coal mine and the actual basis, the construction process of the operation cost management system is as follows:

[0070] 1) Identify resource costs:

[0071] Resource cost refers to the expenditure incurred to complete each operation, including labor costs, material costs, depreciation costs, repair costs, special costs (safety costs, subsidence compensation costs), etc. These are the main detailed items of the existing raw coal costs. However, the cost of completing each operation has not yet been directly reflected in the accounting books and needs to be divided and identified in detail.

[0072] 2) Identify and confirm the main operations and divide the operation centers:

[0073] An operation or operation center is a part of the production process, and each operation is a cost accounting object. Conducting operation analysis and confirming the main operations are the basis for implementing operation cost management. The operation cost system divides the operation and determines the operation center according to the operation process of coal production. Since the enterprise management of the coal mining group is hierarchical and layered, the scope and content of decision-making at each level are different, and the degree of cost information used is different. Therefore, a mixed method can be used to define the operation. There are two main methods: first, divide the operation within the department. Since coal production first collects resource consumption according to various departments such as development team, tunneling team, coal mining team, ventilation team, installation team, electromechanical team, etc., then in cost accounting, the operation accounting objects are divided according to different departments, such as development operation center, tunneling operation center, coal mining operation center, etc. The auxiliary operation department can be divided into electromechanical operation center, transportation operation center, ventilation operation center, lane repair operation center, drilling rig operation center, machine repair operation center, belt operation center and other support systems related to coal production. Second, the operation items are further divided according to the business process. For example, the development operation center includes pre-operation preparation, blasting operation, gangue removal operation, support operation and repair operation, etc., to ensure that the resources are accurately traced to the cost target and the cost of the operation center is controlled. In this way, only the cost information of the process operation is reflected when summarizing to the enterprise group, while detailed information can be provided to the coal mine.

[0074] 3) Allocate the collected resources or input costs to the cost pool of each operation center:

[0075] Cost pool refers to the cost whose cost change is explained by a certain cost driver. Cost pool is set according to the operation center, and each cost pool represents the cost caused by the operation center to which it belongs. In coal enterprises, since the three leading processes of development, excavation and mining are composed of different teams, teams with homogeneous operations can be classified into the same cost pool, that is, homogeneous cost pool. Homogeneous cost pool refers to the cost whose cost change can be explained by a common cost driver. This can reduce the workload of cost accounting.

[0076] 4) Allocate the costs of each operation center to the products:

[0077] Divide the operation centers and allocate various production resources according to cost drivers, calculate the cost of each operation center, and then allocate the cost of each operation center to the raw coal cost, and then transfer it in parallel to the total cost and average cost of the final commercial coal.

[0078] 5) Conduct activity cost analysis, control and evaluation:

[0079] On the basis of the cost accounting management system, the standard operation cost is calculated, the operation cost budget is formulated according to the production operation plan, and budget decomposition, daily early warning and budget difference analysis are carried out to achieve operation cost control. Taking the operation cost as the object, focusing on the completion of each operation and the resources consumed, and based on the cost driver, the relevant information required for cost control is provided in a timely and effective manner, and the cost control responsibility center is set up based on the operation center, and the rewards and punishments of the operation employees are directly linked to their operation responsibility cost control, so as to enhance the cost awareness of managers, give full play to the enthusiasm, creativity and cooperation of the employees of the enterprise, and achieve the purpose of effective cost control.

[0080] Specifically, the core of activity-based cost management lies in the activity analysis and cost driver analysis of the enterprise value chain, distinguishing between value-added and non-value-added activities, and eliminating non-value-added activities by restructuring the value chain and controlling cost drivers, thereby achieving the goal of reducing costs. Among them, identifying and analyzing activities is the first condition.

[0081] The key to dividing operations is the appropriate level of coarseness and fineness. The particularity of coal enterprises determines that if the operations are divided too coarsely, the accuracy of cost calculation results and the effect of cost management using operations will be greatly reduced, which violates the original intention of the operation-based costing method; on the contrary, the total number of operations will be too large, resulting in excessive workload and low management efficiency. Therefore, for coal enterprises, the division of operations should follow the following basic principles: the principle of simplicity, the principle of importance, and the principle of feasibility.

[0082] The principle of simplicity means that when a process or task is decomposed into several operations, it is not easy to be too detailed, as long as it can meet the needs of management, achieve its functions and the process is clear. Of course, simplicity is achieved on the basis of being able to complete a certain operation function. We cannot blindly focus on simplicity and integrate key and important operations, so as to lose the function of the operation.

[0083] The process of coal production is complex and there are many auxiliary links. They are closely related to each other and have different priorities. If the division of each link and each process operation follows the same standard, it will not only increase a lot of work but also affect the efficiency of operation management. Therefore, it is very necessary to distinguish between the main links and auxiliary links in the numerous coal production links. For those links that can create greater profits and are critical, the division of operations should be more precise, otherwise, it can be rough, that is, key operations should be managed with emphasis, and the relationship with auxiliary operations should also be coordinated.

[0084] Before determining the operation, the first thing to consider is whether the designed operation can be smoothly implemented in the current coal enterprise environment, whether it conforms to the actual situation of the coal enterprise, and whether it meets the needs of analysis and management.

[0085] Specifically, there are many methods to identify operations, such as "operation map method", "operation process analysis method", "job process analysis method", "opinion solicitation method", etc., each of which has its own advantages. Among them, the "operation map method" is to draw a detailed map of each department of a coal enterprise (including the above-ground department, underground production department, auxiliary production department, etc.), and identify the operations directly under each department based on the map. However, when there are many cross-departmental operations, the "operation map method" is not appropriate. The "operation process analysis method" relies on drawing an "operation flow chart", that is, drawing a systematic flow chart of the various operation steps required to complete coal production, and measuring and analyzing the operation and its efficiency by adding the personnel required for each step and the time consumed on the chart. The production objects of coal production enterprises are relatively simple, the process flow is easy to identify, and the operation flow is also easy to identify. Therefore, this method is most suitable for those operations directly related to coal production. The job process analysis method relies on drawing a "job flow chart", that is, connecting the various positions required to complete a task, drawing a systematic flow chart, and identifying the operation by adding the work to be completed by each position on the chart. This method is more suitable for the division of local operations, especially for management departments. The "opinion solicitation method" is to ask the supervisors or staff of various departments within the coal enterprise (in a few cases, external experts are also consulted) to confirm certain key issues about the operation. For Mine A, the above methods can be combined to identify operations based on the basic operation chain of the coal enterprise.

[0086] Specifically, in the process of production and operation of coal enterprises, various operations are organically linked together. Various operations form an operation chain from here to there, from top to bottom, from inside to outside, and these chains are intertwined to form a huge operation complex.

[0087] For example, because A Coal Mine is establishing an operation cost calculation system for the first time, it usually selects 20-30 operations. With the maturity of enterprise information technology and the deepening of operation cost management, the types of operations can be appropriately increased, but it should not exceed 100 at most, because the secondary operations added to the huge operation group contribute little to the accuracy of cost calculation. Taking the coal mining process as an example, the process steps are easy to identify, so it is more appropriate to use the "operation process analysis method" to identify the operation.

[0088] The coal mining process can be further subdivided into coal cutting, top coal caving, support and other operations. After the operation is identified, the basic unit of operation cost accounting and the basic object of operation analysis are also clarified.

[0089] Specifically, an activity is the basic unit of a product or service, which consumes resources and generates value-added. In the activity-based costing method, the classification of activities is very important. Classifying activities can better manage costs and improve efficiency. The main methods of dividing activity costs include classification according to production process, classification according to activity scale, classification according to activity complexity, classification according to upstream and downstream relationships of products, and classification according to product mutual supply relationships.

[0090] Classification by production process. Activity-based costing divides operations into direct material operations, direct labor operations, and manufacturing overhead operations according to different production processes. Direct material operations refer to the cost of raw materials directly used in product manufacturing; direct labor operations refer to the labor costs directly used in the product manufacturing process; and manufacturing overhead operations refer to costs related to the production process but cannot be directly attributed to a specific product, such as depreciation of production equipment and factory rent.

[0091] Classify by job size. Activity-based costing can also be classified by the size of the job. Jobs can be divided into large jobs and small jobs according to their size. Large jobs are generally larger in scale and longer in cycle, and involve more costs. Small jobs are relatively smaller in scale, shorter in cycle, and less costly. By classifying jobs by size, you can better control the cost of each job and take corresponding management measures.

[0092] Classify by job complexity. Activity-based costing can also be classified by the complexity of the job. Complexity refers to the technical and operational difficulty involved in the job. Depending on the complexity, jobs can be divided into simple jobs and complex jobs. Simple jobs are generally easy to operate and have lower risks, requiring less cost. Complex jobs require higher technical levels and experience, and may bring higher costs. By classifying the complexity of the job, you can better understand the characteristics and cost structure of each job, and then adopt corresponding management strategies.

[0093] Classification by upstream and downstream relationship of products. Upstream and downstream relationship refers to the production and processing sequence relationship between different products in an industrial chain. Upstream products are usually raw materials or primary products, which become downstream products after processing or transformation. In coal mining operations, if the operations are classified according to the upstream and downstream relationship of products, it means grouping the operations according to their position and order in the production and processing flow of coal mining products. For example, the various operation links in the process from raw coal mining (upstream) to coal processing (such as washing), and then to coal sales or conversion into other products (downstream). Coal mining operations (upstream): including coal mining, tunneling, transportation and other operations, which are directly related to the acquisition of raw coal. Coal processing operations (midstream): such as washing operations, the raw coal is cleaned and screened to improve the quality of coal. Product sales and conversion operations (downstream): including the transportation and sale of coal, or the operation of converting coal into other products (such as coke and coal chemical products).

[0094] Classification by product mutual supply relationship. Product mutual supply relationship refers to the mutual supply relationship between different products within an enterprise or between different enterprises. That is, the production or processing of one product requires another product as a raw material or intermediate product. In coal mines and their related industrial chains, product mutual supply relationships may exist between coal mines and other energy or chemical companies, or between different production links within coal mines. Mutual supply relationship between coal mines and coal chemical enterprises: The coal provided by coal mines is the raw material for coal chemical enterprises (such as coking plants and gasification plants), and the products of coal chemical enterprises (such as coke and synthesis gas) may be returned to coal mines for use as energy or raw materials. Mutual supply relationship between different production links within coal mines: For example, the washing operation within the coal mine may require equipment and service support provided by other operations, and the washed coal becomes the raw material for subsequent processing or sales operations.

[0095] In summary, the classification of activities in the activity-based costing method is based on production processes, operation scale and operation complexity. By rationally classifying activities, costs can be better managed and efficiency can be improved. In actual operations, Coal Mine A should choose a suitable classification method based on its own situation and formulate corresponding management strategies to achieve the goals of cost control and optimization of benefits.

[0096] In combination with the actual situation of Coal Mine A, the management procedures and work scope of each unit are taken as the basis, and each procedure is subdivided according to the characteristics of the technological flow. Full communication is carried out with on-site production technicians to sort out the upstream and downstream or mutual supply relationships of the outputs between the processes. It is determined that the operations of Coal Mine A are divided into six categories: washing operations, direct production operations, auxiliary production operations, production management operations, business management operations and logistics support operations.

[0097] The operation center is a collection of several operations, and its purpose is to facilitate enterprise management and cost accounting. The production and operation process within an enterprise organization often includes multiple interrelated and interconnected operations, such as factories, mines, teams, teams, positions, etc. There is a close chain relationship between these operations, which makes it impossible for traditional management accounting to fully reflect the cost information of each operation, and thus cannot fully and accurately evaluate the cost performance of production and operation activities, which is not conducive to the implementation of cost control and management by enterprises. Therefore, cost accounting is completed through the activity-based costing method. On the basis of the traditional cost calculation method, the concept of operation is introduced, and the operation is regarded as a cost element, and the cost driver is considered as an operation driver. By valuing the resources consumed by the operation, it is allocated to each operation, thus forming an activity-based cost calculation model.

[0098] The operation center is a management accounting unit centered on standard operations or tasks. Each process is subdivided according to the characteristics of the process flow, and the upstream and downstream or mutual supply relationships between the outputs of the processes are sorted out to determine the operation center.

[0099] During the specific implementation process, after determining the operating cost based on the above-mentioned consumption information of the multiple operating centers, the above-mentioned method also includes the following steps: obtaining cost driver information, wherein the above-mentioned cost driver information is a factor affecting the change of the above-mentioned operating cost, and the above-mentioned cost driver information at least includes one or more of the tunnel footage, coal mining tons and transportation times; determining the operating cost based on the above-mentioned cost driver information and the above-mentioned consumption information, and allocating the above-mentioned operating cost to each of the above-mentioned operating centers, wherein the above-mentioned cost driver information and the above-mentioned operating cost are positively correlated.

[0100] In this scheme, cost drivers refer to factors that cause changes in operating costs. Cost driver information includes at least one or more of the following: tunnel footage, coal mining tonnage, and transportation times. These factors are closely related to coal mine operations, and their changes will directly affect the level of operating costs. After obtaining cost driver information and consumption information (such as the type, quantity, and unit price of resource consumption), this information can be used to calculate the cost of each operation and allocate the operating costs. By considering cost driver information, the cost of each operation can be calculated more accurately to ensure the rationality and accuracy of cost allocation.

[0101] Specifically, this plan also includes resource identification, cost collection, cost driver identification, and cost aggregation. Resource identification: Use the financial material cost account to establish resource categories and resource detail catalogs, and aggregate engineering operation materials into the corresponding resources. Cost collection: According to the results of the operation division, the material cost incurred by each operation center is collected through system interfaces, mobile APPs, and data import. Cost driver identification: Identify the cost drivers of each operation center, that is, the factors that determine the change in operation costs. These drivers include: tunnel footage, coal mining tons, number of transportation times, etc. Cost aggregation: Based on the cost drivers, the collected material cost is allocated to each operation center, and further aggregated to specific products (raw coal, etc.).

[0102] The calculation logic of the activity-based costing method is established in a custom relationship. It finds the calculation order and calculates the cost of the activity and the cost of the product according to the service supply and product output and consumption based on a fixed calculation method (direct allocation calculation, indirect allocation calculation, product carry-over calculation).

[0103] Specifically, resources refer to the various resource expenditures incurred by an enterprise in carrying out economic activities within a certain period of time. Resource costs include the expenditure of tangible resources such as houses and buildings, equipment, materials, and commodities, as well as the expenditure of various intangible resources such as information, intellectual property rights, and land use rights, as well as the expenditure of human resources and various other tax expenses.

[0104] In order to facilitate the direct tracing or allocation of resource costs to various operation centers, enterprises can also classify resources into the following five categories according to the relationship between resources and operations at different levels:

[0105] 1) Production-level resources. Including raw materials, parts, labor, energy, etc. obtained for a single product (or service);

[0106] 2) Batch-level resources. Including labor used for production preparation, machine debugging, etc.;

[0107] 3) Product-level resources. These include specialized equipment, software, or manpower required to produce a certain product (or service);

[0108] 4) Customer-level resources. These include specialized equipment, software, and manpower required to serve specific customers;

[0109] 5) Facility-level resources. These include land use rights, houses and buildings, and human resources that are not affected by changes in production, batches, products, services, and customers.

[0110] Product-level resource costs should be directly traced back to the product and other cost objects of each operation center. For other levels of resource costs, reasonable resource drivers should be selected and allocated to each operation center according to the proportion of resource drivers of each operation center. The sum of resource costs consumed by the enterprise to perform each operation constitutes the total cost of that operation.

[0111] Specifically, the cost center is associated with the cost center level and the operation center level. The function module for configuring the association relationship between the two levels includes multiple association configuration modes such as 1 to N, N to 1, and N to N. After association, the costs between the two levels can be associated, so that the corresponding cost information can be seen at any level.

[0112] Specifically, the product catalog is a collection of product details, which are divided into three types according to current business, namely final products, intermediate products and services.

[0113] According to the production process, determine what products each operation unit has. Products include but are not limited to physical products, and also include the generation of service-type costs. For example, the products of auxiliary units can provide services as products to various production units. In this way, product information is extracted.

[0114] The specific products of A coal mine are as follows:

[0115] Final products: mixed coal, small coal, fine coal, gangue;

[0116] Intermediate products: raw coal, excavation footage;

[0117] Services: electromechanical, transportation, ventilation, drainage, disaster prevention, material supply, logistics support, organization and personnel, business management, safety and environmental protection, production technology, dispatching management, and financial management.

[0118] Specifically, a profit center refers to a responsibility center that can control both production and sales and is responsible for both costs and revenues but has no responsibility or power to determine the level of investment in the center's assets. Therefore, the performance of the center can be evaluated based on the amount of profit it makes. In this case, the center is called a profit center.

[0119] There are two types of profit centers:

[0120] 1) Natural profit centers, which sell products directly to outsiders and conduct buying and selling business in the market;

[0121] 2) Artificial profit centers, which mainly sell products within the company at internal transfer prices.

[0122] Specifically, the first step in conducting an operation analysis is to determine the business objectives of the coal enterprise, and then determine and describe the various operations that the coal enterprise performs to provide products or services to customers. Operation analysis specifically includes the following steps:

[0123] The first step is to analyze the necessity of the operation. There are three main criteria for distinguishing between value-added and non-value-added operations: 1) Adjusting the operation will bring about a change in state. 2) The change in state cannot be completed by the previous operation. 3) The operation enables other operations to be performed. Operations that meet these three conditions are value-added operations, and vice versa, they are non-value-added operations. The basic purpose of operation analysis is to distinguish between value-added and non-value-added operations by analyzing the attributes of the operation, and then find ways to improve efficiency, reduce costs and increase profits.

[0124] The second step is to analyze the importance of operations. Coal enterprises generally have dozens or even hundreds of operations, so there is no need to analyze them one by one. Usually, most of the costs of coal enterprises are caused by a few operations. According to the principle of importance, only those operations that are relatively important relative to corporate value and customer value need to be analyzed.

[0125] The third step is to compare operations with those in the same industry. Value-added operations are not necessarily efficient or optimal operations. By comparing with the advanced level operations of other coal enterprises, we can determine whether a certain operation or the entire operation chain of the enterprise is effective and seek opportunities for improvement.

[0126] The fourth step is to analyze the relationship between tasks. The ideal task chain should be one in which tasks are closely linked to each other, with the shortest time and the least number of repetitions required to complete the task, and each necessary task should only appear once in the shortest possible time.

[0127] By analyzing the operations, clarifying the completion status and resource consumption of the operations, considering both technical and economic factors, dynamically adjusting the operation mode, and re-allocating resources, the ultimate goal of operation cost management can be achieved: continuously reducing costs and measuring performance. Therefore, identifying and analyzing operations are the key issues and prerequisites for implementing operation cost management in coal enterprises.

[0128] Specifically, activity cost variance analysis is a method of comparing and analyzing the differences between actual activity costs and budgeted activity costs. The difference between the actual activity costs and the budgeted total is decomposed into the sum of the differences caused by various factors, thereby explaining the causes of the differences and providing directions for cost improvement and control. Activity cost variance analysis can bring the following value to enterprises: (1) Tracking and eliminating adverse differences helps reduce costs; (2) Helps enterprises implement exception management; (3) Provides an information basis for the performance evaluation system. Combining variance analysis with activity cost management can improve the accuracy of performance appraisal in activity cost management, better make production decisions, optimize resource allocation, and thus give full play to the value of activity costing.

[0129] There are four types of activity-based cost variance analysis:

[0130] 1) Analysis of operating costs related to operating time:

[0131] This type of operating cost varies with the operating time (manual hours or machine hours) (such as equipment maintenance work), and is affected by two factors: unit product operating time and unit time cost rate. The difference is divided into consumption difference (also known as efficiency difference) and hourly cost rate difference (price difference).

[0132] Consumption variance (efficiency variance) = (actual operating hours - standard operating hours) × standard hourly cost rate;

[0133] Consumption variance (efficiency variance) = actual output × (actual operating hours per unit product - standard operating hours per unit product) × standard hourly cost rate;

[0134] Hourly cost rate difference (price difference) = actual working hours × (actual hourly cost rate - standard hourly cost rate);

[0135] Hourly cost rate difference (price difference) = actual output × actual working hours per unit product × (actual hourly cost rate - standard hourly cost rate).

[0136] 2) Analysis of operating costs related to the number of operations and the output:

[0137] This type of operation cost varies with the number of operations (such as tunneling operations), and is affected by two factors: the number of operations and the cost of each operation. The difference is divided into two types: the difference in the number of operations (efficiency difference) and the difference in operation costs (price difference).

[0138] Operation volume variance (efficiency variance) = (actual number of operations - standard number of operations) × standard cost per operation;

[0139] Operation cost variance rate (price variance) = actual number of operations × (actual cost per operation - standard cost per operation).

[0140] 3) Analysis of activity costs related to the number of operations but not to output:

[0141] The operation cost analysis formula for this type of operation (such as gas inspection operation) can also be calculated according to the above formula, but the standard operation times in the formula are completely determined by the budget and do not involve production factors.

[0142] 4) Analysis of operational cost differences that are not related to the workload and output:

[0143] The characteristic of this type of manufacturing overhead is that within the normal production capacity, the amount of the overhead has no direct relationship with the workload and product output, for example, depreciation of fixed assets used for production, wages of production management personnel, etc. This characteristic determines that this type of manufacturing overhead should be analyzed from the following perspectives:

[0144] The first is the budget variance. Since this type of fixed cost is not related to the workload and output changes, the budget variance can reveal the difference between the actual amount of the cost and the budgeted amount.

[0145] Budget variance = actual amount of fixed expenses - budgeted amount of fixed expenses;

[0146] The second is the difference in production capacity utilization. This difference mainly reveals the cost of unused production capacity among the available production capacity. The degree of utilization of production capacity shows the degree to which this cost is effective.

[0147] Production capacity utilization variance = (1-actual total machine hours ÷ total machine hours available under normal production capacity) × fixed cost budget.

[0148] Specifically, activity-based benchmarking refers to the process of using the best activity cost of an enterprise as a benchmark to conduct comparative analysis to improve related activity costs. Under the activity-based cost system, benchmarking refers to using the best cost level as the standard for analysis and evaluation. Here, the "best cost level" refers to the best cost level of an enterprise's internal unit (activity center) or the best level of the industry in which the enterprise is located.

[0149] Activity-based cost benchmarking can generally be divided into the following three types, depending on the selected benchmark object and the operational process to be evaluated:

[0150] (1) Internal process benchmarking analysis refers to the mutual evaluation and comparison of the same operating processes of different departments and units within an enterprise.

[0151] (2) External competitive process benchmarking is to use the products, services, and operating processes of the organization's competitors as a benchmark for evaluation and comparison, in an attempt to identify one's own strengths or weaknesses.

[0152] (3) Functional process benchmarking: This type of benchmarking is not limited to the same industry, but selects a specific function or operation process and conducts a benchmark analysis against the best standards in this field.

[0153] When conducting an activity cost benchmark analysis, the ideal benchmark standard is based on a comparative analysis of the activity costs of the internal units of the enterprise, the enterprise's competitors, and the industry in which it operates. In order to make this benchmark analysis effective, the optimal activity cost level of the internal units of the enterprise should be selected as the standard as much as possible, because it is very difficult to obtain an external competitive activity cost benchmark for the enterprise, and even if an external competitive cost benchmark is obtained, it may not be effective. However, if the enterprise can be sure that the external cost benchmark obtained is feasible, reasonable, and effective, it can use this benchmark as an internal standard to improve the enterprise's activity cost structure and reduce costs.

[0154] Specifically, the cost-benefit analysis based on activity-based costing first needs to collect and classify the resources consumed by the product according to the principles of activity-based costing, divide the costs into short-term and long-term parts according to the consumption of resources, and then divide the long-term variable costs into activity costs according to the activity type, and then allocate them to each product according to the consumption of each activity by each product. Secondly, add the allocated activity costs to the short-term variable costs to get the total product cost.

[0155] After using the activity-based costing method to divide the operating costs, the product costs are composed of short-term variable costs and operating costs, and then break-even analysis and sensitivity analysis are performed on this basis. When performing break-even analysis, the marginal contribution of the product no longer needs to cover only fixed costs, but also includes the operating costs allocated according to the operating volume and the allocated fixed costs. The revised cost-volume-profit break-even analysis model formula is as follows:

[0156] The break-even point analysis model is: the break-even point of each product = (allocated operating cost + allocated fixed cost) ÷ (sales unit price - unit short-term variable cost);

[0157] Similarly, after using the activity-based costing method to divide costs, when conducting sensitivity analysis, the object is no longer to explore the relationship between variable costs and profits, but to explore the relationship between long-term variable costs and profits. The sensitivity analysis formula is as follows:

[0158] Sensitivity coefficient of each long-term variable cost = percentage change in profit ÷ percentage change in long-term variable cost;

[0159] The sensitivity coefficient of each workload = profit change percentage ÷ workload change percentage.

[0160] In the specific implementation process, after obtaining the cost driver information, the method further includes the following steps: calculating the standard operating cost of the operation center based on the consumption information, wherein the standard operating cost is the standard value of the product of the quantity of resources of the target type reported in advance and the unit price of the resources of the target type; sending the cost driver information, the standard operating cost and the operation cost to the target terminal, so that the target terminal adjusts the standard operating cost.

[0161] In this solution, the standard operating cost is a standard value calculated based on the number of target resource types reported in advance and the unit price of target resource types. It is sent to the target terminal together with the cost driver information (such as tunnel footage, coal mining tons, etc.) and the actual operating cost (that is, the actual resource consumption cost). After receiving this information, the target terminal will conduct a series of analysis and comparison. It will compare the difference between the actual operating cost and the standard operating cost, analyze the reasons for the difference, and adjust the standard operating cost accordingly. By calculating the standard operating cost and comparing it with the actual operating cost, the actual situation of cost control can be more accurately grasped. This helps to discover cost deviations in a timely manner and take effective measures to correct them. The adjustment process of standard operating costs is actually a process of continuous improvement. Through continuous comparison, analysis and adjustment, enterprises can continuously optimize operating processes, reduce resource consumption, and improve production efficiency.

[0162] Specifically, this plan is based on the theory of activity-based costing, takes cost driver analysis as the starting point, and according to the cost drivers of coal mine projects, the formulation of material quotas is deepened into the operation link, with the operation as the core, and the consumption of materials in the operation process is analyzed to formulate the quota of operating consumables. It mainly includes collecting basic data, analyzing operation consumption, standard operation costs, compiling quota standards, reviewing and publishing quotas, and adjusting and optimizing.

[0163] Collect basic data: Collect basic data related to the compilation of operation consumables quotas, including historical engineering material consumption data, quota standards, construction measures, construction plans, etc. These data will serve as a reference for formulating consumables quotas.

[0164] Analyze operation consumption: Based on the activity-based costing method, analyze the consumption of consumables for each operation, including the type, quantity, unit price, etc.

[0165] Standard activity cost: Based on resource drivers, resource costs are allocated to various activities and the standard cost of each activity is calculated.

[0166] Formulate quota standards: Based on historical data, industry standards and actual production conditions, formulate reasonable quota standards for consumables and establish a standard quota library.

[0167] Quota review and release: Provide review and release process definition for quota tables, and quota version update control.

[0168] Adjustment and optimization: Make necessary adjustments and optimization to the consumables quotas based on the audit results and actual production conditions.

[0169] In some embodiments, determining the operating cost based on the above-mentioned cost driver information and the above-mentioned consumption information can be specifically achieved through the following steps: constructing an operating cost determination model, wherein the above-mentioned operating cost determination model is trained using multiple sets of training data, and each set of training data in the above-mentioned multiple sets of training data includes historical cost driver information, historical consumption information, and historical operating costs corresponding to the above-mentioned historical cost driver information and the above-mentioned historical consumption information obtained within a historical time period; inputting the above-mentioned cost driver information and the above-mentioned consumption information into the above-mentioned operating cost determination model to obtain the above-mentioned operating costs corresponding to the above-mentioned cost driver information and the above-mentioned consumption information.

[0170] In this solution, the operation cost determination model is a prediction model trained based on historical data. It aims to predict or determine the corresponding operation cost by inputting cost driver information and consumption information. By learning these training data through machine learning algorithms or statistical methods, the model can learn the complex relationship between cost driver information and consumption information and operation costs, and build a model that can predict future operation costs based on this. Once the operation cost determination model is built, new cost driver information and consumption information can be input into the model, and the model will automatically calculate the corresponding operation cost according to the rules it has learned. Compared with traditional cost calculation methods, the operation cost determination model based on machine learning or statistical methods can more accurately capture the complex relationship between cost driver information and consumption information and operation costs, thereby more accurately predicting or determining operation costs, greatly shortening the time of cost calculation and improving the efficiency of cost calculation.

[0171] Specifically, we can follow the "five-level" budget management structure, adhere to the principle of "top-down decomposition and bottom-up accounting", use material quotas and operation costing to accurately calculate engineering material costs and unit costs, and decompose them into companies, professions, projects, operations and departments. Use the deviation analysis system to track and analyze budget execution.

[0172] Specifically, first, by clarifying the cost drivers of each operation center, using intelligent algorithms and big data analysis technology, an operation material budget model (i.e., operation cost determination model) is established. Then, basic data is input, for example, the collected basic data (such as material consumption quota, cost driver rate, price, etc.) is input into the budget model. Finally, intelligent budget calculation is performed. The budget model automatically calculates the material requirements, purchase volume, and cost budget of each operation link based on the input data.

[0173] In some embodiments, after sending the above-mentioned consumption information of the multiple above-mentioned operation centers and the above-mentioned operation costs of the multiple above-mentioned operation centers to the target terminal, the above-mentioned method also includes the following steps: obtaining a preset consumption threshold, wherein the above-mentioned preset consumption threshold is the maximum demand for resources consumed to implement the operation; when the above-mentioned consumption information is greater than or equal to the above-mentioned preset consumption threshold, generating a first warning information, and sending the above-mentioned first warning information to the above-mentioned target terminal; obtaining a preset cost threshold, wherein the above-mentioned preset cost threshold is the maximum value of the preset cost of implementing the operation; when the above-mentioned operation cost is greater than or equal to the above-mentioned preset cost threshold, generating a second warning information, and sending the above-mentioned second warning information to the above-mentioned target terminal.

[0174] In this solution, if the consumption information is greater than or equal to the preset consumption threshold, a first warning message is generated and sent to the target terminal. If the calculated operation cost is greater than or equal to the preset cost threshold, a second warning message is generated and sent to the target terminal. By setting the consumption threshold and the cost threshold, the resource consumption and cost situation during the operation can be monitored in real time. Once an abnormality is found (i.e., exceeding the threshold), a warning message is immediately generated. The automatic generation and sending of warning information reduces the workload of manual monitoring and improves management efficiency.

[0175] Assume that a coal mining company sets the following preset thresholds for coal mining operations:

[0176] Preset consumption thresholds: daily coal production does not exceed 1,000 tons, and daily tunnel advancement does not exceed 50 meters.

[0177] Preset cost threshold: daily operating cost does not exceed RMB 500,000.

[0178] On a certain day, the following data was monitored:

[0179] Consumption information: The coal production on that day was 1,050 tons and the tunnel advancement was 52 meters.

[0180] Operating cost: Calculated based on cost driver information and consumption information, the operating cost for the day was RMB 520,000.

[0181] Since the coal mining volume and tunnel footage on that day exceeded the preset consumption threshold, a first warning message was generated and sent to the target terminal. At the same time, since the operating cost on that day also exceeded the preset cost threshold, a second warning message was generated and also sent to the target terminal.

[0182] Specifically, this solution also includes big data analysis, mainly including early warning forecasting, consumables demand forecasting, inventory optimization management, consumables usage analysis and cost-benefit analysis.

[0183] Early warning forecast: Based on historical data, inventory data and current usage, the demand and cost of consumables are predicted, and early warning thresholds are set. When the actual cost approaches or exceeds the early warning threshold, the early warning mechanism is automatically triggered and an early warning notification is sent to relevant personnel. At the same time, the system supports multiple cost control modes and supports managers to make adjustments and optimizations.

[0184] Consumables demand forecasting: Utilize historical sales data, inventory data, production data, etc., combined with machine learning algorithms to build a consumables demand forecasting model to achieve accurate forecasting and avoid inventory backlogs or stockouts.

[0185] Inventory optimization management: Based on real-time inventory data and forecasting models, dynamically adjust procurement plans and production plans, optimize inventory structure, and reduce inventory costs.

[0186] Consumables usage analysis: Analyze consumables usage data, identify abnormal usage behaviors, such as excessive consumption and unreasonable use, and propose improvement measures to reduce waste.

[0187] Cost-benefit analysis: Comprehensively analyze the cost data of each operation link, evaluate the effect of system implementation, and provide data support for continuous optimization.

[0188] In some embodiments, after sending the consumption information of the multiple operation centers and the operation costs of the multiple operation centers to the target terminal, the method further includes the following steps: displaying the consumption information and the operation costs of the multiple operation centers on a display interface of a display device, wherein the display method includes one or more of a bar chart, a line chart, a pie chart, and a table.

[0189] This solution provides a variety of display methods, including bar charts, line charts, pie charts and tables. These methods have their own characteristics and can display the characteristics and trends of data from different angles. Through visual display, users can see the consumption and cost distribution of each operation center at a glance without having to read cumbersome data reports, which improves the efficiency and accuracy of data interpretation.

[0190] Specifically, the mobile application APP in this solution supports managers to record dynamic data of material usage on-site through handheld mobile devices, and supports real-time viewing of cost analysis reports and early warning information. It provides rich visual reporting functions, such as bar charts, line charts, pie charts, etc., to intuitively display information such as consumable usage and cost change trends.

[0191] Specifically, dynamic process monitoring can be carried out in this solution. By deploying IoT monitoring equipment and other equipment in material warehouses and construction sites, as well as handheld mobile apps, key dynamic information such as material collection, use, and inventory can be collected in real time and uploaded to the server for centralized storage, processing, and analysis.

[0192] On-site management is the weak link in material cost control. Through the Internet of Things, mobile APP applications, etc., the dynamic flow of materials can be monitored, from material approval, district team collection, decomposition to work groups, and then to the place of use, the entire process of engineering operation cost tracking record is collected.

[0193] Professionals will compare the budget costs of engineering projects, collect and calculate the consumables costs of the operation center, and carry out pre-, mid- and post-event management and control, implement comprehensive on-site supervision of materials above and below the well, and achieve dynamic control throughout the entire process.

[0194] Specifically, the solution of this application discloses a solution for intelligent monitoring of operating consumables for engineering cost control, which specifically covers multiple aspects such as material quota formulation, operating cost method, dynamic monitoring of consumables, operating cost accounting and big data analysis of coal mine engineering operating consumables.

[0202] The embodiment of the present application also provides a monitoring device for operating consumables for engineering cost control. It should be noted that the monitoring device for operating consumables for engineering cost control of the embodiment of the present application can be used to execute the monitoring method for operating consumables for engineering cost control provided by the embodiment of the present application. The device is used to implement the above-mentioned embodiments and preferred implementation modes, and those that have been described will not be repeated. As used below, the term "module" can implement a combination of software and / or hardware for a predetermined function. Although the device described in the following embodiments is preferably implemented in software, the implementation of hardware, or a combination of software and hardware, is also possible and conceived.

[0203] The following is an introduction to the monitoring device for operating consumables for engineering cost control provided in an embodiment of the present application.

[0204] Figure 3 1 is a structural block diagram of a monitoring device for operating consumables for engineering cost control according to an embodiment of the present application. Figure 3 As shown, the device comprises:

[0205] A first acquisition unit 10 is used to acquire a plurality of operation centers, wherein the operation center is a collection of a plurality of operations responsible for completing the manufacture of a specific product, and the operation is a process in the production process of a coal mine project;

[0206] The second acquisition unit 20 is used to acquire consumption information of the plurality of operation centers, wherein the consumption information is the type, quantity and unit price of resources consumed by the operation centers for pre-implementing operations;

[0207] A first processing unit 30 is used to determine the operation cost according to the consumption information of the plurality of operation centers, and allocate the operation cost to each of the operation centers;

[0208] The first sending unit 40 is used to send the consumption information of the plurality of operation centers and the operation costs of the plurality of operation centers to a target terminal.

[0209] Through this embodiment, the engineering construction process of a coal mine can be decomposed into several independent operation centers, and the consumption and operation costs of each operation center can be clearly calculated. This allows for more refined monitoring of the cost of engineering consumables. After sending it to the target terminal, the staff can promptly understand the cost structure and distribution of consumables of each operation center, thereby solving the problem of the difficulty in effectively monitoring the cost of engineering consumables in coal mines in the prior art.

[0210] During the specific implementation process, the first acquisition unit includes an acquisition module and a classification module. The acquisition module is used to acquire the operation information of the multiple operations mentioned above, wherein the operation information includes one or more of the basic engineering information, the engineering operation process information and the engineering operation material information. The basic engineering information includes one or more of the project name, geographical location, responsible unit and project duration. The engineering operation process information includes one or more of development, excavation, mining, transportation, power supply, ventilation and drainage. The engineering operation material information includes one or more of support materials, equipment accessories, grease, fasteners and sealing materials. The classification module is used to classify the multiple operations mentioned above based on the operation information according to the target classification method to obtain the multiple operation centers mentioned above, wherein the target classification method includes one or more of the production process classification, the operation scale classification, the operation complexity classification, the product upstream and downstream relationship classification and the product mutual supply relationship classification.

[0211] In this solution, operation information can be collected from multiple operations. According to certain target classification methods (such as production process classification, operation scale classification, operation complexity classification, product upstream and downstream relationship classification, product mutual supply relationship classification, etc.), the collected operation information can be used to classify multiple operations. The operations can be classified according to a certain logic and assigned to different operation centers, which will help coal mining enterprises achieve refined management.

[0212] During the specific implementation process, the above-mentioned device also includes a third acquisition unit and a second processing unit. The third acquisition unit is used to obtain cost driver information after determining the operation cost based on the above-mentioned consumption information of the multiple operation centers, wherein the above-mentioned cost driver information is a factor affecting the change of the above-mentioned operation cost, and the above-mentioned cost driver information at least includes one or more of the tunnel footage, coal mining tons and transportation times; the second processing unit is used to determine the operation cost based on the above-mentioned cost driver information and the above-mentioned consumption information, and allocate the above-mentioned operation cost to each of the above-mentioned operation centers, wherein the above-mentioned cost driver information and the above-mentioned operation cost are positively correlated.

[0213] In this scheme, cost drivers refer to factors that cause changes in operating costs. Cost driver information includes at least one or more of the following: tunnel footage, coal mining tonnage, and transportation times. These factors are closely related to coal mine operations, and their changes will directly affect the level of operating costs. After obtaining cost driver information and consumption information (such as the type, quantity, and unit price of resource consumption), this information can be used to calculate the cost of each operation and allocate the operating costs. By considering cost driver information, the cost of each operation can be calculated more accurately to ensure the rationality and accuracy of cost allocation.

[0214] During the specific implementation process, the above-mentioned device also includes a calculation unit and a second sending unit. The calculation unit is used to calculate the standard operating cost of the above-mentioned operation center according to the above-mentioned consumption information after obtaining the cost driver information, wherein the above-mentioned standard operating cost is a standard value of the product of the quantity of resources of the target type reported in advance and the unit price of the resources of the target type; the second sending unit is used to send the above-mentioned cost driver information, the above-mentioned standard operating cost and the above-mentioned operating cost to the above-mentioned target terminal, so that the above-mentioned target terminal adjusts the above-mentioned standard operating cost.

[0215] In this solution, the standard operating cost is a standard value calculated based on the number of target resource types reported in advance and the unit price of target resource types. It is sent to the target terminal together with the cost driver information (such as tunnel footage, coal mining tons, etc.) and the actual operating cost (that is, the actual resource consumption cost). After receiving this information, the target terminal will conduct a series of analysis and comparison. It will compare the difference between the actual operating cost and the standard operating cost, analyze the reasons for the difference, and adjust the standard operating cost accordingly. By calculating the standard operating cost and comparing it with the actual operating cost, the actual situation of cost control can be more accurately grasped. This helps to discover cost deviations in a timely manner and take effective measures to correct them. The adjustment process of standard operating costs is actually a process of continuous improvement. Through continuous comparison, analysis and adjustment, enterprises can continuously optimize operating processes, reduce resource consumption, and improve production efficiency.

[0216] In some embodiments, the second processing unit includes a construction module and a processing module, the construction module is used to construct an operation cost determination model, wherein the above-mentioned operation cost determination model is trained using multiple sets of training data, and each set of training data in the above-mentioned multiple sets of training data includes historical cost driver information, historical consumption information, and historical operation costs corresponding to the above-mentioned historical cost driver information and the above-mentioned historical consumption information obtained within a historical time period; the processing module is used to input the above-mentioned cost driver information and the above-mentioned consumption information into the above-mentioned operation cost determination model to obtain the above-mentioned operation costs corresponding to the above-mentioned cost driver information and the above-mentioned consumption information.

[0217] In this solution, the operation cost determination model is a prediction model trained based on historical data. It aims to predict or determine the corresponding operation cost by inputting cost driver information and consumption information. By learning these training data through machine learning algorithms or statistical methods, the model can learn the complex relationship between cost driver information and consumption information and operation costs, and build a model that can predict future operation costs based on this. Once the operation cost determination model is built, new cost driver information and consumption information can be input into the model, and the model will automatically calculate the corresponding operation cost according to the rules it has learned. Compared with traditional cost calculation methods, the operation cost determination model based on machine learning or statistical methods can more accurately capture the complex relationship between cost driver information and consumption information and operation costs, thereby more accurately predicting or determining operation costs, greatly shortening the time of cost calculation and improving the efficiency of cost calculation.

[0218] In some embodiments, the above-mentioned device also includes a fourth acquisition unit, a third sending unit, a fifth acquisition unit and a fourth sending unit, the fourth acquisition unit is used to obtain a preset consumption threshold after sending the above-mentioned consumption information of the multiple operation centers and the above-mentioned operation costs of the multiple operation centers to the target terminal, wherein the above-mentioned preset consumption threshold is the maximum demand for resources consumed to implement the operation; the third sending unit is used to generate a first warning message when the above-mentioned consumption information is greater than or equal to the above-mentioned preset consumption threshold, and send the above-mentioned first warning message to the above-mentioned target terminal; the fifth acquisition unit is used to obtain a preset cost threshold, wherein the above-mentioned preset cost threshold is the maximum value of the preset cost of implementing the operation; the fourth sending unit is used to generate a second warning message when the above-mentioned operation cost is greater than or equal to the above-mentioned preset cost threshold, and send the above-mentioned second warning message to the above-mentioned target terminal.

[0219] In this solution, if the consumption information is greater than or equal to the preset consumption threshold, a first warning message is generated and sent to the target terminal. If the calculated operation cost is greater than or equal to the preset cost threshold, a second warning message is generated and sent to the target terminal. By setting the consumption threshold and the cost threshold, the resource consumption and cost situation during the operation can be monitored in real time. Once an abnormality is found (i.e., exceeding the threshold), a warning message is immediately generated. The automatic generation and sending of warning information reduces the workload of manual monitoring and improves management efficiency.

[0220] In some embodiments, the above-mentioned device also includes a display unit, which is used to display the above-mentioned consumption information and the above-mentioned operation costs of the multiple operation centers on the display interface of the display device after sending the above-mentioned consumption information of the multiple operation centers and the above-mentioned operation costs of the multiple operation centers to the target terminal, wherein the display method includes one or more of a bar chart, a line chart, a pie chart, and a table.

[0221] This solution provides a variety of display methods, including bar charts, line charts, pie charts and tables. These methods have their own characteristics and can display the characteristics and trends of data from different angles. Through visual display, users can see the consumption and cost distribution of each operation center at a glance without having to read cumbersome data reports, which improves the efficiency and accuracy of data interpretation.
