DETAILED DESCRIPTION

[0022] In order to make the purpose, technical solution and advantages of the embodiments of the present invention clearer, the technical solution in the embodiments of the present invention will be clearly and completely described below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative work are within the scope of protection of the present invention.

[0023] At present, the relevant technologies have the following problems in the process of engineering material management: 1) Waste and inefficiency of materials and supplies: In traditional construction project management, excessive or premature procurement and unreasonable allocation of materials and supplies often lead to waste of resources.

[0024] 2) Information asynchrony: In the absence of an integrated system, the matching degree between material procurement batches and project implementation progress is not high, which affects the timeliness and accuracy of decision-making.

[0025] 3) Scheduling and management difficulties: The lack of accurate material management methods makes project scheduling and resource allocation complex and error-prone.

[0026] To this end, the embodiments of the present invention provide a construction material management method, system, computer device and storage medium to solve the above-mentioned problems in the related art.

[0027] According to an embodiment of the present invention, an embodiment of a construction material management method is provided. It should be noted that the steps shown in the flowchart of the accompanying drawings can be executed in a computer device such as a set of computer executable instructions, and although a logical order is shown in the flowchart, in some cases, the steps shown or described can be executed in an order different from that shown here.

[0028] Figure 1 It is a flowchart of the engineering material management method according to an embodiment of the present invention.

[0029] like Figure 1 As shown, an embodiment of the present invention provides a construction material management method, which is applied to a construction material management system.

[0030] The project materials management method includes: S101: Determine a design bill of materials according to a building information model corresponding to a target project.

[0031] In this embodiment, the target project is a construction project.

[0032] In this embodiment, S101 determines the design material list according to the building information model corresponding to the target project, which specifically includes: obtaining project information of the target project. The project information includes the building information model or engineering drawings.

[0033] Depending on the type of project information obtained, when the project information is an engineering drawing, a building information model is created based on the engineering drawing based on preset modeling rules to generate a design bill of materials.

[0034] When the project information is a building information model, the building information model is checked and revised according to the preset modeling rules, and the design material list is determined.

[0035] In this embodiment, the preset modeling rules require that the components (components, that is, materials) constituting the engineering entity in the building information model have the following properties and can match the material codes in the material database.

[0036] For example, attribute 1: material name, attribute 2: specification description, attribute 3: unit of measurement, attribute 4: engineering quantity (automatically calculated based on model parameters).

[0037] In this embodiment, the design material list is a list of components constituting the engineering entity, including but not limited to the code (the same as the code of the material in the material database), name (the same as the name of the material in the material database), specification description, material and required quantity corresponding to each component. The required quantity of the component can be obtained by adding the loss quantity considering the loss situation according to the number of components in the building information model.

[0038] The corresponding engineering material management system first needs to receive the project information of the target project. When receiving the project information of the target project, it determines the type of the project information of the target project. If the project information is an engineering drawing, it is necessary to create a building information model based on the engineering drawing and the preset modeling rules to generate a design bill of materials. At this time, since the building information model is created according to the preset modeling rules, there is no need to verify and correct the building information model. If the project information is a building information model, it is necessary to verify and correct the building information model according to the preset modeling rules, and determine the design bill of materials based on the verified and corrected building information model.

[0039] In this embodiment, the directly received building information model needs to be checked by using the preset modeling rules, and parts of the model that do not meet the design specifications or actual construction requirements can be found, such as unreasonable connection nodes between beams and columns, missing component material information, etc. After correction, the model is more perfect, and a more accurate design material list is obtained, avoiding material procurement errors or quantity deviations due to model defects.

[0040] When creating a building information model based on engineering drawings, you can follow the preset modeling rules to build a high-quality model and generate a checklist in one go, without the need for subsequent large-scale verification and correction work, saving time and labor costs.

[0041] An accurate design of the bill of materials provides a reliable basis for subsequent material management and other links. Avoid material backlogs or shortages caused by bill errors, and reduce unnecessary material waste and capital occupation. Procuring too much of a certain type of material due to bill errors not only takes up inventory space, but also increases storage costs. An accurate bill can effectively avoid such situations and improve the overall efficiency of material management.

[0042] It can handle two common types of project information, whether it is engineering drawings or building information models. This makes the engineering material management system more versatile in practical applications and can be connected with data provided by different design stages and different participants. The design material list can be obtained through different processes.

[0043] Preset modeling rules are key criteria for ensuring the quality of building information models and the accuracy of design bills of materials, covering various specifications, standards and requirements for model construction. Preset modeling rules can include: Attribute definition rules: Assign detailed attribute information to each component in the model, such as material, strength grade, manufacturer (supplier), etc. For concrete components, the concrete strength grade (e.g., C30), cement type and aggregate characteristics need to be indicated to provide basic data for subsequent material analysis.

[0044] Data association rules: standardize the association relationship between data of different components. For example, establish a dependency relationship between doors and windows and walls to ensure that the opening and closing actions of doors and windows can be correctly presented in the model, and the material information of doors and windows can be associated with the wall information.

[0045] The process of obtaining a design bill of materials based on engineering drawings: First, according to the preset modeling rules, convert the two-dimensional graphics on the engineering drawings into components in the three-dimensional model. According to the attribute definition rules, add corresponding attribute information to these components, such as determining the wall material, thickness and other attributes based on the drawing annotations. Then, according to the data association rules, establish the logical relationship between components, such as the connection relationship between stairs and floors. Based on the fully constructed building information model, through specific algorithms and procedures, extract the quantity, specification description, material and other information of various components in the building information model, combine the attribute information, and generate a design bill of materials. For example, count the length and quantity of different specifications of steel bars in the building information model, calculate the weight of the steel bars based on the steel bar density, and summarize to form a design bill of materials for steel bars.

[0046] The process of obtaining a design bill of materials based on an existing building information model: First, based on the preset modeling rules, check whether the geometric shape and size of the components in the building information model are accurate, such as checking whether the span of the beam and the height of the column meet the design requirements, and correct those that do not meet the requirements. Use the attribute definition rules to check the component attribute information and supplement the missing information, such as supplementing the missing material manufacturer information. Through the data association rules, check whether the association between components is correct, such as whether the connection relationship between pipelines and equipment is reasonable, and make adjustments. After verification and correction, based on the perfect building information model, use algorithms and procedures similar to those mentioned above to extract relevant information in the building information model and generate an accurate design bill of materials. The relevant information in the building information model can be extracted based on the extraction function of the BIM platform to generate a design bill of materials.

[0047] In this embodiment, as an example, verification can be performed through a program interface, and the verification steps are as follows: S1: The design material list that constitutes the engineering entity is derived from the building information type. The design material list includes the unique ID code of each component, as well as the material name, specification description, unit of measurement and other information in the above-mentioned preset modeling rules.

[0048] S2: The material name, specification description, unit of measurement and other information in the above design material list are compared and checked with the information in the material database. The consistent content is passed, and the inconsistent content is handled according to S3.

[0049] S3: Inconsistent content is checked through a combination of AI and manual inspection. If the BIM model is inaccurately expressed, the corresponding BIM model modification requirements are output according to the material database requirements. If the material database is missing, the material database supplement requirements are output.

[0050] S4: The BIM model is modified according to the model modification requirements. Or the material database is improved according to the database supplement requirements.

[0051] S102: Determine the work breakdown structure (WBS) corresponding to the target project, and prepare a construction schedule based on the work breakdown structure.

[0052] In this embodiment, the smallest unit of the work breakdown structure is a work package. The construction schedule includes time attributes corresponding to each work package. The time attributes include start time, duration, and end time.

[0053] In this embodiment, determining the work breakdown structure corresponding to the target project specifically includes: Create a work breakdown structure based on the construction process database and material database corresponding to the target project.

[0054] The construction technology database includes but is not limited to: the processes and acceptance standards for various construction technologies.

[0055] The material database includes but is not limited to: the codes and material properties corresponding to various materials. Material properties include: material name, specification description and measurement unit.

[0056] As an example, construction technology refers to the method used to complete a certain work task of the project, including the required labor, turnover materials, auxiliary materials, construction equipment, electricity consumption and water consumption, etc. The information of auxiliary materials and construction equipment is also stored in the material database.

[0057] The specific implementation steps are as follows: Based on the analysis of the project, the engineering technicians select one or more construction techniques for the various tasks of the project. They supplement the necessary measures to complete the physical construction of the project, such as scaffolding, etc. They decompose the structure according to the material constraints of the project construction, such as foundation, main structure, roof engineering, electromechanical engineering, decoration, etc.

[0058] As an example, the specific method of determining the work breakdown structure corresponding to the target project can be: Analyze the construction process database: The construction process database records the processes and acceptance standards of various construction processes. First of all, it is necessary to comprehensively sort out the construction processes involved in the target project and determine the process links. For example, for a construction project, it may involve multiple process links such as foundation construction, main structure construction, decoration and renovation. Taking foundation construction as an example, its process may include site leveling, earth excavation, foundation steel bar binding, formwork installation, concrete pouring and other steps. At the same time, it is necessary to clarify the acceptance standards for each step, such as the depth and slope deviation range of earth excavation, and the strength grade requirements of concrete.

[0059] Study the material database: The material database contains the codes and material properties corresponding to various materials. According to the design requirements of the target project, select the materials required for each process link in the construction process involved in the target project from the material database. For example, in the construction of the main structure, different specifications of steel bars, cement, sand and gravel are required. These materials can be accurately identified and managed through material coding, and the specific requirements of materials can be determined based on material properties (such as material name, specification description and unit of measurement).

[0060] Work decomposition: Based on the analysis of the target construction process (the construction process involved in the target project) and the material database, the target project is gradually decomposed into multiple relatively independent and manageable work units, namely work packages. The following principles should be followed during decomposition: Deliverables orientation: Each work package should have clear deliverables. For example, the deliverable of the foundation reinforcement tying work package is to complete the specified number and specifications of reinforcement tying and meet the design and acceptance criteria.

[0061] Moderate decomposition: Work packages should not be too large and complex, making them difficult to manage and control, nor too small and trivial, increasing management costs. Generally speaking, the duration of a work package should be a few weeks, but the specific duration should be determined based on the scale and complexity of the project.

[0062] Clear logical relationship: There should be clear logical relationship between work packages, such as sequence, parallel relationship, etc. For example, the foundation reinforcement binding work package can only be carried out after the earthwork excavation work package is completed.

[0063] Constructing WBS hierarchy: Organize the decomposed work packages according to a certain hierarchy to form a WBS. Usually, WBS can be divided into multiple levels, with the top level being the entire target project, the next level being each major project phase or sub-project, and the next level being the specific work packages. For example: The first level: target project (such as a construction project).

[0064] The second layer: foundation engineering, main structure engineering, decoration and renovation engineering, etc.

[0065] The third layer: earth excavation work package, foundation steel bar binding work package, main concrete pouring work package, etc.

[0066] As an example, here is how to prepare a construction schedule based on a work breakdown structure: Determine the time attributes of each work package.

[0067] Start time: Determine the earliest start time of each work package based on the logical relationship between the work packages. For example, the start time of the foundation reinforcement binding work package depends on the completion time of the earthwork excavation work package.

[0068] Duration: Combine the construction process flow and experience data in the construction process database and the supply of materials in the material database to estimate the duration of each work package. For example, based on the experience of previous similar projects, the duration of the earthwork excavation work package may be 5 days, but if the geological conditions are complex, the duration may be longer.

[0069] End Time: Calculate the end time of each work package based on the start time and duration. For example, if a work package starts on May 1 and lasts for 3 days, the end time is May 3.

[0070] Draw a construction schedule chart: You can use tools such as Gantt charts and network diagrams to draw construction schedule charts. Taking the Gantt chart as an example, the horizontal axis represents time, the vertical axis represents work packages, and each work package is represented by a bar chart. The length of the bar chart represents the duration of the work package, and the starting position of the bar chart represents the start time of the work package. The Gantt chart can intuitively display the time arrangement and relationship of each work package, which is convenient for project managers to monitor and coordinate progress.

[0071] Optimize the construction schedule: After the preliminary construction schedule is prepared, it needs to be optimized. The goal of optimization is to arrange resources reasonably and reduce costs while meeting the project duration requirements. Optimization can be performed by adjusting the start time, duration or logical relationship of the work package. For example, if it is found that the resource demand is too concentrated in a certain period of time, the start time of the relevant work package can be appropriately adjusted to achieve a balanced allocation of resources.

[0072] Determining the work breakdown structure corresponding to the target project and preparing a construction schedule requires comprehensive consideration of factors such as construction technology and material supply to ensure that the project can be completed on time, with quality and quantity.

[0073] S103: Determine the material requirement list (construction material list) corresponding to each work package in the construction schedule according to the design material list and construction material list (CBOM) processing principles. Summarize the material requirement list and time attributes corresponding to each work package to determine the summary material list corresponding to the target project.

[0074] In this embodiment, the material requirement list corresponding to each work package in the construction schedule is determined according to the processing principles of the design material list and the construction material list, so that the material information in the design stage can be accurately converted into the material list required in the construction stage, ensuring that the material specifications, models and other parameters meet the construction requirements. Figure 2 shown.

[0075] As an example, the processing logic of the smallest unit work package of the work breakdown structure in the process of converting the design bill of materials to the construction bill of materials, that is, the specific construction bill of materials processing principles include: Figure 3 Contents shown: There is a one-to-one relationship with the Design Bill of Materials (DBOM): the DBOM code is associated with the WBS code.

[0076] There is a one-to-many relationship with the design material list: multiple DBOM codes are associated with WBS codes respectively.

[0077] There is a many-to-one relationship with the design material list: the DBOM code is split into sub-codes and associated with different WBS codes.

[0078] There is a many-to-many relationship with the design material list: the association with the WBS code is completed according to a combination of one-to-many and many-to-one.

[0079] The loss amount is scattered: based on the DBOM summary, the loss rate of each sub-item is added.

[0080] Auxiliary materials-consumables calculation: Calculate the consumption of each item based on the workload of the work package.

[0081] Auxiliary materials - circulating materials: Evaluate the loss and availability of circulating materials according to the work package schedule.

[0082] Tools: Evaluate the status and availability of tools according to the work package schedule.

[0083] In this embodiment, the processing principle of the construction material list is a pre-set processing principle. For example, for materials with clear calculation formulas, the calculation is strictly based on the formula. For example, the number of bricks required for wall construction is calculated based on the wall area, thickness and brick specifications. For complex components or special construction conditions, a combination of simulation analysis or empirical data is used. For example, the calculation of the template usage of special-shaped building structures can be carried out by using a three-dimensional simulation analysis with the help of a BIM model, combined with the empirical data of previous similar projects, to comprehensively determine the specifications and quantity of the template to ensure the accuracy of the material requirement list.

[0084] According to the design bill of materials and CBOM processing principles, determine the material requirement list corresponding to each work package, which can be done in the following steps: Sort out the correspondence between the design bill of materials and work packages: According to the association rules of DBOM code and WBS code, clarify the correspondence between various materials in the design bill of materials and each work package in the construction schedule.

[0085] One-to-one relationship processing: If there is a one-to-one relationship, that is, one DBOM code corresponds to one WBS code, the material information in the design bill of materials is directly mapped to the corresponding work package. For example, a specific model of doors and windows, whose code in DBOM uniquely corresponds to an exterior window installation work package, then the specifications, quantity and other information of the doors and windows are used as the basic material requirement data for this work package.

[0086] One-to-many relationship processing: When a one-to-many relationship occurs and multiple DBOM codes are associated with the same WBS code, the material information corresponding to these DBOM codes needs to be summarized. Taking the concrete pouring work package as an example, concrete of different strength grades may correspond to different DBOM codes, but they all serve this work package. The required quantity, strength grade and other information of these different specifications of concrete need to be summarized and integrated.

[0087] Many-to-one relationship processing: For many-to-one relationships, that is, splitting DBOM codes into sub-codes and associating them with different WBS codes, it is necessary to carefully analyze the material usage corresponding to each sub-code and its association with each work package. For example, a large equipment may have multiple components. After its DBOM code is split into sub-codes, they correspond to different work packages such as equipment installation and commissioning. The specifications and quantities of the corresponding materials must be determined according to the actual needs of each work package.

[0088] Many-to-many relationship processing: For many-to-many relationships, the association is completed in a combination of one-to-many and many-to-one. For example, in an electrical installation project, wires and cables of various specifications (multiple DBOM codes) correspond to different electrical equipment installation and line laying work packages (multiple WBS codes). It is necessary to comprehensively consider various factors and accurately match materials and work packages.

[0089] Calculate material loss: Based on the DBOM summary, consider the loss rate of each sub-item to determine the actual material demand. Different types of materials have different loss rates. For example, the loss rate of wood during processing may be 5%-10%, and the loss rate of steel during cutting and welding is about 2%-5%. Determine the loss rate of each type of material in each work package based on specific construction technology and experience data, and then calculate the loss amount. Assuming that a work package requires 100 cubic meters of wood and the loss rate is 8%, the actual wood demand is 100×(1+8%)=108 cubic meters.

[0090] Determine the need for auxiliary materials and tools: Auxiliary materials-consumables calculation: Calculate the consumption of each item according to the workload of the work package. For example, for a painting work package, calculate the total consumption of paint according to the area to be painted and the amount of paint used per unit area. If 0.2 liters of paint is required per square meter of wall, and a work package is responsible for painting 1,000 square meters of wall, the paint consumables required are 1,000×0.2=200 liters.

[0091] Auxiliary materials - turnover materials: Evaluate the loss and availability of turnover materials based on the work package schedule. For example, for formwork engineering, calculate the number of turnovers of the formwork and the loss of each turnover based on the construction cycle of the concrete pouring work package. If the formwork is expected to be turned over 5 times, the loss rate of each turnover is 3%, and a total of 100 square meters of formwork is required, the amount of formwork invested for the first time needs to be adjusted considering the loss to ensure the supply of formwork during the construction process.

[0092] Tools: Evaluate the status and availability of tools based on the work package schedule. For example, in a pipeline installation work package, if the work cycle is long and some tools are easily worn, it is necessary to prepare spare tools in advance or arrange regular maintenance, and determine the required number of tools based on time and frequency of use.

[0093] S104: Determine the material management strategy based on the summary bill of materials and the supplier database.

[0094] In this embodiment, the material management strategy is determined based on the summary material list and the supplier database, specifically including: Determine the demand information corresponding to each type of material based on the summary bill of materials. The demand information includes but is not limited to: demand address, material category, demand time and demand quantity.

[0095] Determine the supply information corresponding to each supplier based on the supplier database. Supply information includes but is not limited to: supply category, price, supply quantity, production cycle, supply address, transportation time, transportation cost and storage space.

[0096] Determine the material management strategy based on the demand information corresponding to each type of material and the supply information corresponding to each supplier.

[0097] You can build a multi-objective optimization function with the goal of minimizing total cost and maximizing resource utilization, set corresponding constraints, and determine the strategy model based on the multi-objective optimization function and constraints. Determine the material management strategy through the strategy model.

[0098] As an example, a multi-objective optimization function is constructed with the minimum total cost and the maximum resource utilization as the goals. Usually, these two goals can be weighted and combined to form a comprehensive objective function.

[0099] Let C be the total cost, including material procurement cost, transportation cost, etc. R is the resource utilization rate. Assume that the weight of cost is a, the weight of resource utilization is b, and a+b=1. Then the multi-objective optimization function F can be expressed as: F=aC+bR.

[0101] The total cost C can be calculated based on the purchase price of the material, transportation cost, etc. m represents the number of suppliers, n represents the number of material categories, Provide the unit price of the jth material to the i-th supplier, is the quantity of the jth material purchased from the i-th supplier, is the unit transportation cost of transporting the jth material from the ith supplier.

[0102] Resource utilization R can be measured by the degree of matching between the supply and demand of materials. For example, it can be expressed as the ratio of supply to demand.

[0103] Set up constraints: Constraints are used to limit the range of decision variables to ensure the feasibility of the strategy. Common constraints include: Material requirement constraints: For each material j, the total amount of material purchased from all suppliers should meet the demand. is the demand for the jth material, then: .

[0104] Supplier supply capacity constraints: The quantity of each material provided by each supplier cannot exceed its supply capacity. is the maximum supply quantity of the jth material by the i-th supplier, then: .

[0105] Time constraints: The supply time of materials should meet the demand time of the project. is the supply time for purchasing the jth material from the i-th supplier, is the demand time of the jth material, then: .

[0106] Choose an appropriate optimization algorithm to solve the model: According to the constructed multi-objective optimization function and constraints, a suitable optimization algorithm can be selected to solve the model to find the optimal material management strategy. Common optimization algorithms include: linear programming algorithm, genetic algorithm, etc.

[0107] Determine the optimal materials management strategy: After solving the model through the optimization algorithm, we can get a set of optimal decision variable values, that is, the purchase quantity of each material from each supplier. Based on these optimal values, the optimal material management strategy can be determined, including: Supplier Selection: according to The value of determines which suppliers should be selected for each material. , it means that the jth material should be purchased from the i-th supplier.

[0108] Procurement plan formulation: according to According to the value of the material, formulate a procurement plan for each material, including the procurement quantity, procurement time, etc. At the same time, arrange logistics transportation and warehousing management according to the supplier's supply information.

[0109] Cost and resource utilization assessment: Calculate the total cost and resource utilization based on the optimal strategy to evaluate the effectiveness of the strategy. If necessary, adjust the weights based on the actual situation and re-solve the model to find a material management strategy that better meets your needs.

[0110] By constructing a multi-objective optimization function, setting constraints, and selecting an appropriate optimization algorithm to solve the model, the optimal material management strategy can be determined to achieve the goals of lowest cost and highest resource utilization.

[0111] As another example, the above solution is implemented as follows: Input the material demand plan, that is, determine the demand information corresponding to each type of material based on the summary bill of materials. Obtain the production capacity of multiple suppliers from the supplier database, such as monthly capacity, weekly capacity, production cycle, etc.

[0112] Evaluate the location of the supplier's production base, the distance from the construction site, transportation time, and transportation cost.

[0113] Analyze the available storage space such as yards and warehouses in different time periods of the target project.

[0114] Based on demand plan, supplier capacity and storage capacity, dynamic programming method is used to select the best demand matching solution.

[0115] Evaluate the matching degree of supplier supply capacity: Compare the material categories and demand quantities in the material demand information with the supply categories and supply quantities in the supplier supply information. For special-specification steel required for the project, select suppliers that can provide the corresponding categories and supply quantities that meet the demand. If a supplier can supply common steel but cannot meet the quantity of special-specification steel, it can be excluded or listed as a candidate. It is also necessary to consider the matching degree between the supplier's production cycle and the material demand time. For materials with urgent demand, choose suppliers with short production cycles. For materials with long-term stable demand, you can choose suppliers with slightly longer production cycles but lower costs.

[0116] Weigh cost factors: Calculate the supply costs of different suppliers, including material prices, transportation costs, etc. Compare the prices of the same materials provided by various suppliers, and select the supplier with the lowest total cost based on transportation costs. For suppliers that are far away from the project site but have lower prices, evaluate whether the increase in transportation costs outweighs the price advantage. Consider discounts for bulk purchases and preferential policies for long-term cooperation. If a supplier gives discounts for purchases that reach a certain volume, you can reasonably plan the purchase volume according to project needs to reduce costs.

[0117] Consider logistics and warehousing factors: Evaluate the supplier's logistics delivery timeliness based on the supply address and transportation time. For perishable or urgently needed materials, choose suppliers with short transportation time. For large projects, consider the supplier's storage space. If the storage space on the project site is limited, the supplier can provide certain storage services to relieve pressure. It is also necessary to formulate a reasonable logistics plan based on the project construction progress and material demand time to ensure that materials are supplied on time and in appropriate quantities to avoid backlogs or shortages.

[0118] Comprehensive risk assessment and response: Analyze the reputation and stability of suppliers, check their historical supply records, contract performance, etc. Suppliers with poor reputation and frequent supply problems should be selected with caution even if the cost is low. The impact of market fluctuations on suppliers should also be considered. For example, fluctuations in raw material prices may affect suppliers' supply prices and supply volumes. Develop a multi-supplier strategy and select multiple suppliers for key materials to reduce the risk of a single supplier.

[0119] S105: Implement material management strategies according to the construction schedule.

[0120] Implementing material management strategies according to the construction schedule is a key link in ensuring the smooth progress of engineering projects and the rational use of resources. It mainly covers aspects such as material procurement, logistics distribution, and site management.

[0121] Material procurement execution: Based on the material demand time and demand quantity at each stage in the construction schedule, purchase orders are issued to selected suppliers in accordance with the established material management strategy. During the main structure construction phase, purchase the corresponding amount of steel bars, cement and other materials in advance as planned. During the procurement process, strictly follow the terms of the contract such as price and quality standards to ensure that the purchased materials meet the requirements. Closely track the execution of purchase orders, communicate with suppliers in a timely manner, understand the progress of material production, and if there are problems that may affect supply, such as shortage of raw materials, production equipment failure, etc., negotiate solutions in a timely manner, adjust procurement plans or find alternative suppliers to ensure that materials are supplied on time.

[0122] Logistics and distribution management: Plan reasonable logistics routes and transportation methods based on the supplier's supply address, transportation time and project demand address. For suppliers that are relatively close, choose road transportation to ensure transportation flexibility and timeliness. For large quantities of materials and long distances, railway or water transportation can be considered to reduce costs. During transportation, strengthen the protection and supervision of materials to prevent damage and loss of materials. Take moisture-proof measures for materials such as cement that are easily affected by moisture. Take special packaging and fixing methods for fragile glass products. At the same time, track the logistics status in real time, and use the logistics information system to keep abreast of the material transportation location and estimated arrival time in a timely manner, so as to make preparations for receiving in advance.

[0123] Construction site material management: After the materials arrive at the construction site, arrange the material storage location reasonably according to the construction schedule and site layout plan. Place commonly used materials in a convenient location to reduce the transportation distance and time cost. Set up special storage areas for dangerous materials, such as flammable and explosive paints and acetylene, and strictly abide by safety regulations. Distribute materials accurately according to the construction progress and the actual needs of the work package. Adopt a quota-based material collection system to control the amount of materials used and avoid waste. In the concrete pouring work package, calculate the required amount of concrete based on the project volume, distribute it according to the quota, and recycle and reuse the remaining materials in a timely manner.

[0124] S106: Acquire the business process data generated during the execution of the material management strategy, and adjust the material management strategy according to the changes in the supplier database and the business process data.

[0125] In this embodiment, the business process data is used to monitor the material management strategy. The business process data includes: construction schedule execution, unplanned change information, material production information, transportation information, arrival information, usage information and loss information. The material management strategy may include material procurement strategy and material transportation strategy. The business process data includes: project schedule execution, material production, transportation, arrival, usage, loss, unplanned changes: such as traffic restrictions, changes in plan execution caused by abnormal weather, etc.

[0126] In this embodiment, as time changes, the supplier's capacity will be occupied or released due to order delivery or changes, resulting in changes in the supplier's quotation. The optimal material procurement strategy can be re-planned based on the changed capacity, price, logistics and other information to reduce costs while meeting engineering production needs.

[0127] In an optional embodiment, the technical solution of the present invention further includes: After the target project is completed, the construction process database and material database are updated.

[0128] Evaluate material management strategies based on preset evaluation indicators.

[0129] In this embodiment, after completion, the loss and use of each material in the process database can be recorded to see if there are any changes, and the updated data is convenient for subsequent projects. The material database can be updated to supplement the turnover materials, the addition and reduction of consumable materials, etc., for the convenience of subsequent projects.

[0130] In this embodiment, the material management efficiency can be evaluated and compared in a quantitative manner. The preset evaluation indicators may include: Material procurement capital turnover rate: calculated by the ratio of output value to the working capital occupied by material procurement in the same period.

[0131] Material procurement cost savings ratio: Compare the actual material procurement cost of this project with the procurement cost of similar projects and the cost benchmark set during the project planning phase to arrive at the cost savings ratio.

[0132] Material quality pass rate: comparison between the qualified quantity and the total quantity.

[0133] On-time material arrival rate: comparison between the number of on-time arrivals and the total number of arrivals.

[0134] Average number of times materials are moved: Count the total number of times materials are moved from arrival to storage and then to final use, and then compare it with the number of times the materials are used.

[0135] Average storage period of materials: Summarize the time from when each type of material enters storage to when it is used, and then divide it by the number of times the material is used.

[0136] The present invention realizes digital and precise management of engineering materials by integrating the building information model, decomposing the construction process into a work breakdown structure according to the construction process database, and generating a material requirement list according to the material database.

[0137] The technical effects that can be achieved by the technical solution of the present invention are: 1) Improve the accuracy of material management: Through the detailed data provided by BIM technology, accurate forecasting and planning of material needs can be achieved.

[0138] 2) Optimize resource allocation: Use WBS to structure the construction process to ensure that resource requirements at each stage are reasonably met.

[0139] 3) Reduce waste and improve efficiency: Through refined material management, reduce unnecessary advance purchase of materials and unnecessary storage costs, while improving the construction efficiency of the entire project.

[0140] 4) Real-time monitoring and adjustment: The integrated monitoring system allows the management team to track the use of materials in real time and adjust resource allocation and construction plans in a timely manner to cope with changes in project progress.
