Description

Technical Field

[0001] The present invention belongs to the technical field of production management, and relates to a production management system and method based on multi-production line scheduling optimization. Background Art

[0002] Traditional production planning is a production management model centered on planning and static scheduling, aiming to allocate and dispatch materials and equipment through advance planning. Traditional production planning is suitable for large-scale production with stable demand, such as high-volume manufacturing of standard products. However, traditional production planning lacks flexibility and is difficult to adapt to changes that arise during the production process.

[0003] For example, poor inventory management during the production process may lead to a shortage or surplus of accessories, and a poor match between main parts and accessories will lead to increased production costs and waste of resources, affecting production efficiency.

[0004] In addition, traditional production plans lack effective real-time monitoring methods, making it difficult to promptly detect and resolve production problems. Problems accumulated in the production process cannot be effectively resolved, affecting long-term production efficiency. Summary of the Invention

[0005] In order to solve the problems existing in the background technology, the present invention proposes a production management system and method based on multi-production line scheduling optimization.

[0006] In order to achieve the above object, the technical solution adopted by the present invention is as follows:

[0007] In one aspect, the present invention provides a production management method based on multi-production line scheduling optimization, comprising:

[0008] First, ERP determines the main part production plan, and then MES splits the work orders within the main part production plan. MES releases the parts demand in batches to the parts dynamic matching module based on the main part production progress.

[0009] After the dynamic parts matching module matches demand, the WMS verifies inventory. If the parts inventory is sufficient, the parts are delivered to the buffer area. If the parts inventory is insufficient, the JIT parts production line is triggered to replenish the parts. After the parts are delivered to the buffer area, the WMS verifies inventory again until the parts inventory is replenished.

[0010] Checking whether the ratio of the main part to the accessory is a first preset ratio through the accessory dynamic matching module, and if it is matched, entering the next main part production schedule; the first preset ratio is set according to the change of the main part production schedule;

[0011] The production information feedback module monitors the production progress of main parts and accessories in real time;

[0012] After the main parts production plan is completed, actual consumption statistics are taken, and post-production matching verification is performed through the verification module. MES modifies the demand release rules based on the post-production matching verification results.

[0013] Furthermore, the MES splits the work orders in the master production plan by:

[0014] The main part production schedule is divided into multiple main part production nodes. The main part production schedule includes the assembly process of the main part and accessories, and the matching relationship between the main part and accessories is set.

[0015] Furthermore, the specific method of checking the ratio of the main component to the accessories through the accessories dynamic matching module is as follows:

[0016] Calculate the ratio between the planned stocking quantity of main parts and the actual stocking quantity of accessories. Suppose that N main parts are required in the planned stocking quantity of main parts, and N' accessories are actually used to assemble one main part in actual production. Then the ratio is ;

[0017] like , that is, insufficient spare parts inventory, increase demand release, according to the preset ratio To increase the demand release of subsequent accessories, that is, the new demand release ;

[0018] like , that is, the spare parts are overstocked, reducing the demand release, according to the preset ratio Reduce the demand for subsequent accessories and release new demand ;

[0019] If \Delta N\in \left [ {A,B} \right ] , that is, the accessories inventory is reasonable.

[0020] Furthermore, if , advance the release time node and reduce the release batches;

[0021] like , postpone the release time node and increase the release batch.

[0022] Furthermore, the dynamic matching module for accessories checks whether the ratio of the main part to the accessory is a first preset ratio. If not, the dynamic matching module for accessories dynamically adjusts the production capacity of the JIT accessory production line and the production efficiency of the main part.

[0023] If the ratio is less than the second threshold, the next main part production schedule is entered.

[0024] If the ratio is greater than the first threshold, the production capacity of the JIT accessories production line and the main part production efficiency will be dynamically adjusted, and the ratio of the main part to the accessory will be checked again through the accessories dynamic matching module until the ratio of the main part to the accessory meets the first preset ratio and enters the next main part production schedule.

[0025] Furthermore, MES modifies the work order splitting rules based on the post-production matching verification results.

[0026] In another aspect, the present invention provides a production management system based on multi-production line scheduling optimization, which executes the above-mentioned production management method based on multi-production line scheduling optimization during operation, including:

[0027] ERP, determine the master parts production plan;

[0028] MES splits the work orders within the main part production plan, releases the parts demand in batches to the parts dynamic matching module based on the main part production progress, obtains the post-production matching verification results, and modifies the work order splitting rules;

[0039] Figure 2 It is a system structure diagram of the present invention. DETAILED DESCRIPTION

[0040] The following will clearly and completely describe the technical solutions in the embodiments of the present invention in conjunction with the accompanying drawings. Obviously, the described embodiments are only 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 ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0041] like Figure 1-Figure 2 As shown, the technical solution adopted by the present invention is as follows.

[0042] In one aspect, the present invention provides a production management method based on multi-production line scheduling optimization, comprising:

[0043] First, ERP determines the main part production plan, and then MES splits the work orders within the main part production plan; MES releases the accessories demand to the accessories dynamic matching module in batches based on the main part production progress.

[0044] After the dynamic matching module for accessories matches the demand, the WMS verifies the inventory. If the accessories inventory is sufficient, the accessories will be delivered to the buffer area. If the accessories inventory is insufficient, the JIT accessories production line will be triggered for replenishment. After the accessories are delivered to the buffer area, the WMS will verify the inventory again until the accessories inventory is replenished.

[0045] The dynamic matching module of accessories is used to check whether the ratio of the main part to the accessory is a first preset ratio. If it matches, the next main part production schedule is entered; the first preset ratio is set according to the change of the main part production schedule.

[0046] If there is no match, the dynamic matching module of accessories will dynamically adjust the production capacity of the JIT accessories production line and the main parts production efficiency.

[0047] If the ratio is less than the second threshold, the production process proceeds to the next main part.

[0048] If the ratio is greater than the first threshold, the production capacity of the JIT accessories production line and the main parts production efficiency are dynamically adjusted, and the ratio of the main parts to the accessories is checked again through the accessories dynamic matching module until the ratio of the main parts to the accessories meets the first preset ratio, and then the next main parts production schedule is entered.

[0049] The production information feedback module monitors the main parts production progress and accessories production progress in real time.

[0050] After the main parts production plan is completed, actual consumption statistics are taken, and post-production matching verification is performed through the verification module. MES modifies the demand release rules based on the post-production matching verification results.

[0051] First, the ERP determines the master part production plan, which is then distributed to the MES. The MES then splits the work orders within the master part production plan. The ERP master part production plan provides macro-level guidance and planning for the entire production process, clarifying production goals and direction. The MES splits the work orders, dividing the master part production schedule into multiple master part production nodes and defining matching relationships between master parts and accessories. This makes production tasks more detailed and specific, facilitating subsequent production organization and management, and improving the operability of the production plan.

[0052] The main part production schedule is divided into multiple main part production nodes. The main part production schedule includes the assembly process of the main part and accessories, and sets the matching relationship between the main part and accessories. By dividing the production nodes and setting the matching relationship, the connection between each link and element in the production process is clearly defined, which helps to rationally arrange production resources, improve production efficiency, ensure the coordinated production of main parts and accessories, and avoid production disconnection.

[0053] MES releases component demand in batches to the dynamic component matching module based on the main component production schedule. This allows component supply to match the main component production schedule, preventing premature or late component delivery, reducing inventory backlogs and stockout risks, optimizing supply chain operations, and improving production continuity and stability.

[0054] After the dynamic matching module for accessories matches the demand, the WMS verifies the inventory. If the accessories inventory is sufficient, the accessories are delivered to the buffer area. If the accessories inventory is insufficient, the JIT accessories production line is triggered to replenish the parts. After the parts are delivered to the buffer area, the WMS verifies the inventory again until the accessories inventory is replenished. The WMS verifies the inventory to ensure the accuracy of the accessories inventory quantity and provide reliable material support for production. When the inventory is insufficient, the JIT accessories production line is triggered to replenish the parts, which realizes the timely supply of accessories, avoids production stagnation due to accessories shortages, and improves production efficiency. The inventory is verified multiple times until the replenishment is completed, which ensures the adequacy of the inventory and lays the foundation for the smooth progress of subsequent production.

[0055] The dynamic accessory matching module checks whether the ratio of the main part to the accessory matches a first preset ratio. If so, the production process proceeds to the next main part. This first preset ratio is set based on the main part production schedule. Checking the main part to accessory ratio allows for timely identification of accessory usage during production, ensuring a balanced production ratio between main parts and accessories, avoiding wasted or insufficient accessories, and improving the efficiency of production resources. Setting the first preset ratio based on the main part production schedule allows for adaptability to different production stages.

[0056] Calculate the ratio between the planned stocking quantity of main parts and the actual stocking quantity of accessories. Suppose that N main parts are required in the planned stocking quantity of main parts, and N' accessories are actually used to assemble one main part in actual production. Then the ratio is .

[0057] like Insufficient inventory, increase demand release, according to the preset ratio To increase the demand release of subsequent accessories, that is, the new demand release .like , release the time node in advance and reduce the released batches.

[0058] like , that is, the spare parts are overstocked, reducing the demand release, according to the preset ratio Reduce the demand for subsequent accessories and release new demand .like , postpone the release time node and increase the release batch.

[0059] If \Delta N\in \left [ {A,B} \right ] ], that is, the inventory of accessories is reasonable.

[0060] Rationally adjusting the release volume based on excess or surplus parts consumption can promptly correct resource allocation deviations during production, avoid resource waste or shortages, optimize the allocation of production resources, and improve the economic benefits of production. Adjusting release schedules and batches based on part inventory deviations further optimizes the supply rhythm of parts, making their supply more closely aligned with actual production needs and increasing production flexibility and adaptability.

[0061] The dynamic parts matching module checks whether the ratio of main parts to accessories meets a first preset ratio. If not, it dynamically adjusts the JIT parts production line's production capacity and main part production efficiency. When the ratio of main parts to accessories is mismatched, dynamically adjusting the JIT parts production line's production capacity and main part production efficiency can rebalance each link in the production process and ensure smooth production.

[0062] If the ratio is less than the second threshold, the production process proceeds to the next main part. If the ratio is greater than the first threshold, the production capacity of the JIT parts production line and the main part production efficiency are dynamically adjusted. The dynamic parts matching module then checks the main part to accessory ratio again until it meets the first preset ratio. This ensures that the production ratio of main parts to accessories always meets the requirements, improving production stability and quality.

[0063] The production information feedback module monitors the progress of main and accessory production in real time. This real-time monitoring of production progress allows for the timely identification of problems and anomalies that arise during the production process, providing real-time data support for production management. This allows managers to take timely measures to adjust and address issues, ensuring the smooth execution of production plans.

[0064] After the master part production plan is completed, actual consumption statistics are collected, and post-production matching verification is performed through the verification module. The MES then adjusts the demand release rules based on the results of the post-production matching verification. This process of actual consumption statistics and post-production matching verification allows for the analysis of lessons learned during the production process and the identification of deficiencies in production scheduling management. The MES adjusts the demand release rules based on the verification results, making production management more scientific and rational, continuously optimizing the production process, improving production efficiency and quality, and reducing production costs.

[0065] MES modifies work order splitting rules based on post-production matching verification results. Modifying work order splitting rules can make work order splitting more consistent with actual production conditions, improve the accuracy and feasibility of production plans, further optimize production processes, and improve production efficiency and resource utilization efficiency.

[0066] In another aspect, the present invention provides a production management system based on multi-production line scheduling optimization, which executes the above-mentioned production management method based on multi-production line scheduling optimization during operation, including:

[0067] ERP, determine the master parts production plan;

[0068] MES splits the work orders within the main part production plan, releases the parts demand in batches to the parts dynamic matching module based on the main part production progress, obtains the post-production matching verification results, and modifies the work order splitting rules;

[0073] Verification module, post-production matching verification.

[0074] This invention can be applied to the assembly of large-scale equipment, where a single main component is combined with a variety of accessories. For example, in engine assembly, the main component is the engine block, and accessories include various transmission components, spark plugs, studs, and other parts. With the engine block as the main component, flexible production lines can be used to coordinate various components to meet actual production needs.

[0075] This invention can also be applied to the production of small industrial products by assembling a batch of main components with a variety of accessory parts. For example, in the assembly of a charger, the main components are the housing and circuit board, and the accessories include various types of circuit components such as resistors, capacitors, and diodes. With the housing and circuit board as the main components, flexible production lines can be used to produce various components to meet actual production needs.
