Description

Technical Field

[0001] The present invention relates to the technical field of production scheduling systems, and in particular to a production planning management method and system based on market and resource analysis. Background Art

[0002] ERP (Enterprise Resource Planning) is a management platform based on information technology, which uses systematic management ideas to provide decision-making and operational means for enterprise decision-makers and employees. MPS (Master Production Schedule) is one of the core modules of the ERP system. It is a specific product production plan formulated by manufacturing companies based on MDS (Master Demand Schedule), inventory status, production capacity constraints, etc. It is used to clarify the product models, quantities and time to be produced in each future cycle. It is the core link between the planning end and the execution end. The use of MPS can better achieve the refinement of production goals and the balance between production capacity and demand, thereby guiding material procurement to ensure that delivery commitments are fulfilled on time and in quantity. However, the MPS module of the ERP system is usually based on the assumption of unlimited production capacity and cannot reasonably match order requirements and resource capabilities, resulting in the possibility that the production plan cannot be executed.

[0052] A production planning management method and system based on market and resource analysis according to some embodiments of the present invention will be described below with reference to the accompanying drawings.

[0053] like Figure 1 As shown, the first aspect of the present invention proposes a production planning management method based on market and resource analysis, comprising:

[0054] Obtaining a pre-configured production plan decision cycle, where the production plan decision cycle is a dynamic update cycle of the pre-configured production plan;

[0055] Obtain order data and resource data from the order management system and resource management system respectively;

[0056] Construct a resource consumption model to reflect the resource types and quantities of various resources consumed or used in the production and processing of each product;

[0057] Using the order data, predict the market demand for each product in the next production planning decision cycle;

[0058] evaluating the resource supply capability of the resource management system to meet the market demand for each product based on the resource consumption model;

[0059] The production plan for each product is dynamically updated based on the resource supply capabilities.

[0060] Specifically, the production plan decision cycle is a dynamic update cycle for a pre-configured production plan. Specifically, the present invention dynamically adjusts the production plan for each production plan decision cycle by analyzing market demand and resource capabilities. Changes in market demand can be reflected through changes in order volume. The step of obtaining order data from an order management system specifically includes obtaining historical order data for completed production and order data for uncompleted production from the order management system, and utilizing this order data to perform market demand analysis.

[0061] The resources referred to in the present invention are various types of production resources required for the production or processing of order products, including but not limited to production material resources, production and processing equipment resources, consumables resources of production and processing equipment, and human resources. The production material resources include the raw materials and / or molds required for the production or processing of order products. The products referred to in the present invention are divided according to their types and specifications. That is, in the technical solution of the present invention, when the same type of order products have different specifications, they are also regarded as different products and their resource consumption models are constructed separately. For example, tires with different patterns or different sizes need to have their resource consumption models constructed separately.

[0062] Depending on how resources are used to produce or process products, resource data includes non-renewable resource data and renewable resource data. Non-renewable resource data refers to data on various resources consumed during the production process, such as production material data and consumables used by production and processing equipment. Renewable resource data refers to data on various reusable resources used during the production process, such as the number of various types of production and processing equipment, transportation equipment, and the number of production and processing operators.

[0063] Resource data can be divided into historical resource data, resource inventory data, and resource replenishment data based on when the resource data was generated. Historical resource data includes data on the amount of resources consumed or used to complete historical orders. Resource inventory data includes data on the amount of available resources in current warehouses and factory workshops. Resource replenishment data includes data on the replenishment rate of various non-renewable resources.

[0064] Furthermore, the resource management system includes a material management system for managing product production materials, an equipment management system for managing product production and processing equipment and production and processing equipment consumables, and a personnel management system for managing production personnel. In the step of obtaining resource data from the resource management system, the resource data includes production material inventory data, the number of available production and processing equipment, the number of available consumables, and work schedule data, etc. The resource data also includes replenishment rate data for production materials and production and processing equipment consumables. The replenishment rate data for production materials and production and processing equipment consumables can be entered by operators during each production planning decision cycle, or obtained from the material management system and production and processing equipment management system.

[0065] Furthermore, the step of using the order data to predict the market demand for each product in the next production planning decision cycle specifically includes:

[0066] Obtaining historical order quantities of one or more production planning decision cycles from the order data;

[0067] Constructing the historical order volume into a time data series, wherein the time data series is constructed from a plurality of discrete order volumes in chronological order;

[0068] The time data series is input into a time series prediction model to predict the order quantity of the next production planning decision cycle.

[0069] Specifically, the time series prediction model can be a traditional statistical prediction model such as an autoregressive model or a moving average model, or a machine learning model such as a long short-term memory network model or a gradient boosting decision tree model.

[0070] Furthermore, the step of evaluating the resource supply capability of the resource management system in response to the market demand for each product based on the resource consumption model specifically includes:

[0071] Determine the target output p of each product corresponding to the market demand in the next production planning decision cycle i , where i is 1 to n pd A positive integer between pd is the number of product types;

[0072] Obtain the resource consumption r of the jth resource consumed or used per unit product of the i-th product from the resource consumption model corresponding to the i-th product ij , where j is 1 to n pm，i A positive integer between pm，i The quantity of resource type consumed or used to produce or process product i;

[0073] Calculate the resource consumption R of the jth resource consumed or used by the i-th product in the next production planning decision cycle ij =p i ×r ij ;

[0074] Based on the resource data, calculate the inventory quantity K of the jth resource consumed or used by the i-th product at the beginning of the next production planning decision cycle. ij ;

[0075] Based on the resource quantity R ij With the inventory quantity K ij Evaluate the resource supply capability S of the resource management system for the i-th product in the next production planning decision cycle i .

[0076] In the technical solution of the present invention, the quantity of each product is measured based on the unit product. The unit in the unit product referred to in the present invention is a specific unit configured according to the type of product produced or processed. Depending on the measurement unit of the product, the so-called unit product can be a product, a group of products or a portion of a product. For example, when the product produced and processed is a tire, the unit product can be a tire. When the product produced and processed is in the form of gas, liquid or powder and cannot be measured in units of "pieces", its unit product can be expressed in configured weight units, volume units or other measurable units. Therefore, the target output p i Refers to p i Units of product i, where p i It can be any value greater than or equal to 0, such as 100 tires. i The size of is positively correlated with the size of the production planning decision cycle.

[0077] In the technical solutions of some embodiments of the present invention, for non-renewable resources, the inventory quantity K of the jth resource consumed or used by the i-th product at the beginning of the next production plan decision cycle is calculated based on the resource data. ij The steps specifically include:

[0078] Obtain the first inventory quantity of each non-renewable resource at the beginning of the current production planning decision cycle;

[0079] Determine the consumption and replenishment quantity of each non-renewable resource in the current production planning decision cycle;

[0080] Calculating a second inventory quantity of each non-renewable resource so that the second inventory quantity is equal to the first inventory quantity minus the consumed quantity plus the replenished quantity;

[0081] The second inventory quantity is determined as the inventory quantity of the corresponding non-renewable resources at the beginning of the next production plan decision cycle.

[0082] In the technical solutions of some embodiments of the present invention, for renewable resources, the inventory quantity K of the jth resource consumed or used by the i-th product at the beginning of the next production plan decision cycle is calculated based on the resource data. ij The steps specifically include:

[0083] Get the unit conversion factor of the pre-configured renewable resource quantity;

[0084] The length of the production plan decision cycle is multiplied by the unit conversion coefficient as the inventory quantity of the corresponding renewable resources at the beginning of the next production plan decision cycle.

[0085] Furthermore, based on the resource quantity R ij With the inventory quantity K ij Evaluate the resource supply capability S of the resource management system for the i-th product in the next production planning decision cycle i The steps specifically include:

[0086] With [1, n pd ] represents the number of the corresponding product type, and traverses [1, n pd ];

[0087] The number of the product type currently traversed is represented as i t To do this:

[0088] judge Is there j in the range? t satisfy

[0089] when There is j in the range t satisfy When calculating the resource management system for the i t Resource supply capacity of this product in the next production planning decision cycle:

[0090]

[0091] Specifically, t is 1 to n pd Integer value between . Similarly, j t is 1 to n pm，i Integer value between . t Value and j t Value Satisfaction When, it means that the i t The jth product consumed or used t The inventory quantity of resources at the beginning of the next production planning decision cycle is insufficient to meet the needs of the first t The production demand of a product in the next production planning decision cycle.

[0092] In the technical solution of the above embodiment, when the value of i is in [1, n pd ] range and j value is There is any i in the range t Value and j t Value Satisfaction When , the resource supply capacity of the resource management system for the i-th product in the next production planning decision cycle is represented by the inventory demand ratio corresponding to the resource with the smallest ratio of inventory quantity to the demand quantity of the corresponding resource.

[0093] Furthermore, in judging Is there j in the range? t satisfy After the steps, it also includes:

[0094] when j does not exist in the range t satisfy When calculating the resource management system for the i t Resource supply capacity of this product in the next production planning decision cycle:

[0095]

[0096] Specifically, for [1, n pd Any i in the range t , when the value of j is There is no j in the range t Value Satisfaction When, it means that the i t The inventory quantity of various resources consumed or used by the product can meet the requirements of the first production plan decision cycle at the beginning of the next production plan decision cycle. t The production demand of a product in the next production planning decision cycle.

[0097] In the technical solution of the above embodiment, when j does not exist in the range t satisfy When using the i t The resource supply capacity of the resource management system for the i-th product in the next production planning decision cycle is calculated by the ratio of the inventory quantity of each resource consumed or used by the i-th product to its demand quantity.

[0098] Furthermore, the step of dynamically updating the production plan of each product according to the resource supply capacity specifically includes:

[0099] Determine whether there are resource-conflicting products. The resource-conflicting products are products that consume or use the same one or more resources, and the inventory quantity of the one or more resources consumed or used cannot meet the usage requirements of all resource-conflicting products in the next production planning decision cycle;

[0100] When there are resource-conflicting products, obtain the production priority of each resource-conflicting product;

[0101] The production plan of the resource-conflicting product in the next production plan decision cycle is updated according to the production priority and the resource supply capacity.

[0102] Furthermore, the step of updating the production plan of the resource-conflicting product in the next production plan decision cycle according to the production priority and the resource supply capacity specifically includes:

[0103] Determine whether there are products whose resource supply capacity in the next production planning decision cycle is less than 100% and whose priority is greater than a preset priority threshold;

[0104] When there is a product whose resource supply capacity in the next production planning decision cycle is less than 100% and whose priority is greater than a preset priority threshold, the shortage resources of the corresponding product are determined;

[0105] Generate resource shortage warning information for the corresponding resource, the resource shortage warning information including the name, type and shortage data information of the shortage resource, and the resource shortage warning information also including product information that needs to consume or use the shortage resource.

[0106] Furthermore, after determining whether there is a product whose resource supply capacity in the next production plan decision cycle is less than 100% and whose priority is greater than a preset priority threshold, the method further includes:

[0107] When there is a product whose resource supply capacity in the next production plan decision cycle is less than 100% and whose priority is greater than a preset priority threshold, the production schedule of the corresponding product in the next production plan decision cycle is canceled.

[0108] Furthermore, after determining whether there is a product whose resource supply capacity in the next production plan decision cycle is less than 100% and whose priority is greater than a preset priority threshold, the method further includes:

[0109] For products whose resource supply capacity in the next production planning decision cycle is greater than 100%, their production plans in the next production planning decision cycle are scheduled according to their priority;

[0110] Determine whether there are products with the same production priority and resource supply capacity greater than 100% in the next production planning decision cycle;

[0111] When there are products with the same production priority and resource supply capacity greater than 100% in the next production plan decision cycle, their production plans in the next production plan decision cycle will be scheduled from large to small according to their resource supply capacity in the next production plan decision cycle.

[0112] Furthermore, a resource consumption model is constructed to reflect the resource types and quantities of various resources consumed or used in the production and processing of each product, specifically including:

[0113] Extracting the renewable resource data used in the production and processing of the i-th product from the resource data to generate a renewable resource usage table in the resource consumption model of the i-th product, the renewable resource usage table including the resource name of the renewable resource used in the production and processing of the i-th product and the resource quantity of the renewable resource used in the production and processing process;

[0114] The non-renewable resource data consumed in the production and processing of the i-th product is extracted from the resource data to generate a non-renewable resource usage table in the resource consumption model of the i-th product, wherein the non-renewable resource usage table includes the resource name of the non-renewable resource used in the production and processing of the i-th product and the resource quantity of the non-renewable resource used in the production and processing process.

[0115] Specifically, the resource consumption model consists of a renewable resource usage table that reflects the resource type and resource quantity of renewable resources used in the production and processing of each product, and a non-renewable resource usage table that reflects the resource type and resource quantity of non-renewable resources consumed in the production and processing of each product.

[0116] Furthermore, the step of extracting the non-renewable resource data consumed in producing and processing the i-th product from the resource data to generate a non-renewable resource usage table in the resource consumption model of the i-th product specifically includes:

[0117] Extracting historical resource data for producing and processing the i-th product from the resource data;

[0118] Counting the amount of each non-renewable resource consumed per unit of product produced and processed based on the historical resource data;

[0119] The resource name and resource quantity of each non-renewable resource consumed in producing and processing a unit product of the i-th product are correspondingly written into the non-renewable resource usage table.

[0120] Furthermore, the step of calculating the amount of each non-renewable resource consumed per unit of product produced and processed based on the historical resource data specifically includes:

[0121] Count the number of product i produced or processed in a production batch using a pre-configured unit of measurement;

[0122] Count the resource quantity of each non-renewable resource used in producing or processing the production batch;

[0123] The total amount of resources is divided by the number of products in the production batch to obtain the amount of resources consumed in producing a unit of product.

[0126] Determine the resource quantity of each type of recycled resource used in producing and processing a unit product of the i-th product based on the historical resource data;

[0127] The resource name and resource quantity of each renewable resource used in the production and processing of a unit product of the i-th product are correspondingly written into the renewable resource usage table.

[0128] In some cases, the production of a unit of a product typically requires only one renewable resource, such as a certain type of production equipment or a mold of a certain specification. In other cases, the production of a unit of a product may require the simultaneous use of several renewable resources, such as requiring several operators to perform the production and processing operations.

[0129] Furthermore, the renewable resource usage table also includes the length of time the renewable resources are used to produce and process a unit product of the i-th product. After determining the quantity of each renewable resource used to produce and process a unit product of the i-th product based on the historical resource data, the table further includes:
