Description

Technical Field

[0001] The present invention relates to the technical field of product decomposition method and system module, and in particular to a product decomposition method, a system module and a readable storage medium. Background Art

[0002] In the hardware jewelry industry, product decomposition lacks industry-specific standards and cannot accurately reflect the characteristics of materials and processing technology. The bill of materials (BOM) is disconnected from the processing procedures, and the two fail to establish a close correspondence. The BOM only lists the required materials, while the processing procedures describe the production steps, which makes it difficult for production personnel to quickly associate the materials required for specific processes during execution, increasing the difficulty of finding and reducing efficiency. There are also challenges in the progress management of the production process. The lack of systematic production scheduling and process time estimation leads to unstable production progress and unreasonable resource scheduling. Due to the lack of real-time progress tracking and feedback mechanism, managers cannot adjust production plans in time, which in turn affects the connection and production efficiency of the entire production chain. Therefore, a product decomposition method, system module and readable storage medium are proposed to solve the above problems. Summary of the invention

[0054] A readable storage medium suitable for a system module.

[0055] Specifically, the working principle of the product decomposition method, system module and readable storage medium is as follows: the present invention is based on the characteristics of the hardware accessories industry and the characteristics of its industry products, and according to the shape, function, wearing position, etc. of its products, constructs and sets industry-standard and standardized related data models in the data model library. Considering that at present, product decomposition, cost accounting and production planning mainly rely on personnel experience and subjective judgment, lack of unified standards, and it is difficult to meet professional requirements. The scheduling is unclear and the production progress depends on on-site scheduling, resulting in disconnected processes and delayed progress, and the lack of a real-time feedback mechanism increases management difficulty. To this end, the present application provides a set of industry standard, standardized and unified data models to improve the standardization, standardization and uniformity of product decomposition.

[0056] Combined with the characteristics of the hardware jewelry industry and the characteristics of its products, according to the shape, function, wearing position, etc. of its products, its products are divided into different types, and its product types are pre-set. These models are applicable to the current industry and products, and can be continuously expanded and updated with the development of the industry and the research and development of new products to ensure continuous applicability. According to the characteristics of the hardware jewelry industry and the shape, function, wearing position, etc. of its products, industry professionals build standardized data models in the data model library. Professionals configure and build industry standard data models in the M-1 module. First, industry professionals classify products according to the shape, function, wearing position, etc. of industry products, such as rings, earrings, necklaces, etc., and configure and build product type models. According to which materials the product type consists of, including the name, material, brand, size and other attributes of the material, the material model of the current product type is configured and built. According to the current product type and material model, the processing procedure of the current material is set, including the name, processing requirements, color, surface effects, etc. of the procedure, and the process model under the current material model is configured and built. In this way, the combined process model under the current product type is configured and built.

[0057] The user then performs product decomposition, determines the type of the current product, injects the value of the current product type into the M-2 model acquisition module, and obtains the material model under the current product type. The user selects the corresponding material model based on the actual requirements of the current product, such as a material model, process model, or combined process model.

[0058] According to the actual requirements of the product, the corresponding materials and material attributes, processing procedures and processing requirements, combined procedures and combined requirements, the corresponding values ​​are injected into the M-3 construction module to obtain the decomposition structure of the current product, and according to the decomposition structure of the current product, fill in the product quantity, single piece usage and processing unit price of the corresponding processing procedures, and inject the corresponding values ​​into the M-4 calculation module to obtain the processing quantity of the processing procedures of the current product and the production cost of the product. Processing procedure quantity = product quantity * single piece usage, product cost = the sum of processing procedure costs (single piece usage * process processing unit price).

[0059] The present invention realizes accurate tracking and transparent management of material consumption and production costs by detailed decomposition of material and process costs. The system integrates material and process costs, realizes automatic accounting of the total cost of a single product, generates detailed cost composition reports, provides multi-product cost comparison function, identifies high-cost materials or processes and makes optimization suggestions, thereby effectively reducing overall production costs.

[0060] According to the decomposition structure of the current product and the processing quantity of the decomposition process of the current product, the decomposed processing process is scheduled, and the corresponding values ​​are injected into the M-5 planning and scheduling module to obtain the planned delivery date of the processing process of the current product and the planned delivery date of the product. Each decomposed process is scheduled according to the actual production capacity of the corresponding "producer". The corresponding values ​​are injected into the M-5 planning and scheduling module to obtain the planned delivery date of the processing process of the current product and the planned delivery date of the product. In this way, the estimated completion time is set for each process, and the start and end time of each process and the order of connection are clarified. Through this method, the continuity and flexibility of the production process are guaranteed, which significantly improves the overall production efficiency and makes the product delivery time more accurate.

[0061] According to the decomposition structure of the current product, the processing quantity of the decomposition process and the planned delivery period of the process. Inject the corresponding values ​​into the M-6 production plan module to obtain the production plan and production process of the current product, and actually monitor the production progress of the current product to see whether it is executed according to the production plan. In this way, the present invention realizes real-time monitoring of production progress and optimization of resource allocation. By real-time tracking of the production status of each process, the system can automatically remind when the process is delayed or completed ahead of schedule, ensuring synchronization of the plan with the actual progress, facilitating optimization of the production process and improving production efficiency.

[0062] The present invention also provides a system module;

[0063] When the user enters the product decomposition page, the system acquisition module injects the corresponding data into the "acquisition model unit" and initiates a request to the data model library. The "verification and judgment unit" of the data model library receives the request from the "acquisition model unit" and verifies whether the corresponding data exists in the data model library. If so, the data model library returns the corresponding data model. If not, it returns the corresponding reminder. Users can [Customize] to add settings for product decomposition. The product decomposition structure construction module M-3 injects the corresponding data values ​​into the "construction module" based on the relevant decomposition data such as materials, processing procedures, and combination procedures of the current product decomposition to obtain the decomposition structure of the current product.

[0064] According to the materials and processing procedures, the "second judgment unit" judges that the current processing procedure is greater than or equal to 1. If the current product processing procedure is greater than or equal to 1, the "combination process model" of the current product is obtained from the data model library according to the "acquisition model unit". In combination with the characteristics and requirements of the current product, the corresponding "combination process model" is selected. The "third verification judgment unit" will also verify whether the data of the decomposed materials, processing procedures, etc. of the current product are complete. When the "second judgment unit" fails to pass the verification, the system will give a corresponding error reminder. When the "second judgment unit" passes the verification, the corresponding data will be injected into the "construction module" to obtain the decomposition structure of the current product. The product decomposition structure includes the materials (BOM list of materials), processing procedures, and combination procedures required for the current product; intuitive material and processing procedure association mapping, each material corresponds to a clear processing procedure, and each procedure also corresponds to a specific processing material.

[0065] According to the product breakdown structure and the production process of the processing procedure, the planned delivery date of the processing procedure is verified. The start date of the subsequent processing procedure cannot be earlier than the start date of its previous procedure. The planned delivery date of the processing procedure = planned end date - planned start date. The planned delivery date of the product = the latest end date of the procedure in the breakdown structure - the earliest start date of the procedure in the breakdown structure.

[0066] The present invention sets up devices used by the system module, which include a memory and a processor. The processor is used to execute a computer program stored in the memory to implement a product decomposition method, and the readable storage medium is a computer-readable storage medium. The computer-readable storage medium may include: a U disk, a mobile hard disk, a read-only memory (ROM), a random access memory (RAM), a magnetic disk or an optical disk, and other media that can store program codes.
