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, which aims to achieve the allocation and scheduling of materials and equipment through advance planning. Traditional production planning is suitable for large-scale production with stable demand, such as mass production of standard products. Traditional production planning lacks flexibility and is difficult to cope with changes in 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 may 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 discover and solve problems in production. 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: On the one hand, the present invention provides a production management method based on multi-production line scheduling optimization, comprising: First, ERP determines the main part production plan, and then MES splits the work orders in the main part production plan; MES releases the parts demand to the parts dynamic matching module in batches according to the main part production progress; After the dynamic matching module of the parts matches the demand, the WMS verifies the 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 the inventory again until the parts inventory is replenished. 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; The production information feedback module monitors the production progress of main parts and accessories in real time; After the main parts production plan is completed, actual consumption statistics are taken, and post-production matching verification is carried out through the verification module. MES modifies the demand release rules according to the post-production matching verification results.

[0007] Furthermore, the MES splits the work orders in the main part production plan by: 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.

[0008] Furthermore, the specific method of checking the ratio of the main component to the accessory through the accessory dynamic matching module is as follows: Calculate the ratio between the planned stocking quantity of main parts and the actual stocking quantity of accessories. Suppose that the planned stocking quantity of main parts requires N main parts, and in actual production, N' accessories are actually used to assemble one main part. Then the ratio ; 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 ; 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 ; If \Delta N\in \left [ {A,B} \right ] , that is, the accessories are reasonably stocked.

[0009] Furthermore, if , advance the release time node and reduce the released batches;

[0010] like , postpone the release time node and increase the release batch.

[0011] Further, the dynamic matching module for accessories checks whether the ratio of the main component 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 component. If the ratio is less than the second threshold, the next main part production schedule is entered. If the ratio is greater than the first threshold, the production capacity and main part production efficiency of the JIT parts production line 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.

[0012] Furthermore, MES modifies the work order splitting rules based on the post-production matching verification results.

[0013] On the other hand, 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: ERP, determine the master parts production plan; MES, splits the work orders in the main parts production plan, releases the parts demand to the parts dynamic matching module in batches according to the main parts production progress, obtains the post-production matching verification results and modifies the work order splitting rules; Production information feedback module, real-time monitoring of main parts production progress and accessories production progress and feedback to MES; WMS, to verify the inventory of accessories; The dynamic matching module for accessories can trigger the JIT accessory production line to start production or enter the next main part production schedule based on the matching status of the main part and the accessory.

[0017] Figure 1 is a flow chart of the method of the present invention; Figure 2 It is a system structure diagram of the present invention. DETAILED DESCRIPTION

[0018] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. 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 creative work are within the scope of protection of the present invention.

[0019] like Figure 1-Figure 2As shown, the technical solution adopted by the present invention is as follows.

[0020] On the one hand, the present invention provides a production management method based on multi-production line scheduling optimization, comprising: 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 according to the main part production progress.

[0021] After the dynamic matching module for accessories matches the demand, WMS verifies the inventory. If the accessories inventory is sufficient, the accessories will be delivered to the cache area. If the accessories inventory is insufficient, the JIT accessories production line will be triggered for replenishment. After the accessories are delivered to the cache area, WMS will verify the inventory again until the accessories inventory is replenished.

[0022] 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.

[0023] 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.

[0024] If the ratio is less than the second threshold, the next main part production schedule is entered.

[0025] If the ratio is greater than the first threshold, the production capacity of the JIT parts 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 enters the next main parts production schedule.

[0026] The production information feedback module monitors the main parts production progress and accessories production progress in real time.

[0027] After the main parts production plan is completed, actual consumption statistics are taken, and post-production matching verification is carried out through the verification module. MES modifies the demand release rules according to the post-production matching verification results.

[0028] First, the main part production plan is determined by ERP, and ERP sends the main part production plan to MES. Then MES splits the work orders in the main part production plan. ERP determines the main part production plan, provides macro guidance and planning for the entire production process, and clarifies the production goals and directions. MES splits the work orders, divides the main part production schedule into multiple main part production nodes, sets the matching relationship between the main part and the accessories, makes the production tasks more detailed and specific, facilitates the subsequent production organization and management, and improves the operability of the production plan.

[0029] 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 the various links and elements in the production process is clearly defined, which helps to reasonably arrange production resources, improve production efficiency, ensure that the production of main parts and accessories can be carried out in coordination, and avoid production disconnection.

[0030] MES releases the demand for accessories to the dynamic matching module of accessories in batches according to the production schedule of the main parts. Releasing the demand for accessories in batches according to the production schedule of the main parts can match the supply of accessories with the production schedule of the main parts, avoid the supply of accessories too early or too late, reduce inventory backlog and out-of-stock risks, optimize the operation of the supply chain, and improve the continuity and stability of production.

[0031] After the dynamic matching module for accessories matches the demand, WMS verifies the inventory. If the inventory of accessories is sufficient, the accessories will be delivered to the cache area. If the inventory of accessories is insufficient, the JIT accessories production line will be triggered for replenishment. After the accessories are delivered to the cache area, WMS will verify the inventory again until the accessories inventory is replenished. WMS verifies the inventory to ensure the accuracy of the accessories inventory quantity and provide reliable material guarantee for production. When the inventory is insufficient, the JIT accessories production line is triggered to replenish, which realizes the timely supply of accessories, avoids production stagnation due to accessories shortage, 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.

[0032] The dynamic matching module of accessories is used to check whether the ratio of the main part to the accessories is the first preset ratio. If it matches, the next main part production schedule is entered. The first preset ratio is set according to the changes in the main part production schedule. Checking the ratio of the main part to the accessories can timely discover the rationality of the use of accessories in the production process, ensure the coordination of the production ratio of the main part and the accessories, avoid the waste or shortage of accessories, and improve the utilization efficiency of production resources. Setting the first preset ratio according to the changes in the main part production schedule can meet the needs of different production stages.

[0033] Calculate the ratio between the planned stocking quantity of main parts and the actual stocking quantity of accessories. Suppose that the planned stocking quantity of main parts requires N main parts, and in actual production, N' accessories are actually used to assemble one main part. Then the ratio .

[0034] 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 earlier and reduce the released batches.

[0035] 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.

[0036] If \Delta N\in \left [ {A,B} \right ] ], that is, the inventory of accessories is reasonable.

[0037] According to the overconsumption or surplus of accessories, the demand release quantity can be reasonably adjusted to timely correct the resource allocation deviation in the production process, avoid resource waste or shortage, optimize the allocation of production resources, and improve the economic benefits of production. According to the deviation of accessories inventory, the release time nodes and batches are adjusted to further optimize the supply rhythm of accessories, so that the supply of accessories is more in line with the actual production needs, and the flexibility and adaptability of production are improved.

[0038] The dynamic matching module for accessories checks whether the ratio of the main part to the accessory is the first preset ratio. If it does not match, the dynamic matching module for accessories dynamically adjusts the capacity of the JIT accessory production line and the production efficiency of the main part. When the ratio of the main part to the accessory does not match, dynamically adjusting the capacity of the JIT accessory production line and the production efficiency of the main part can rebalance each link in the production process and ensure smooth production.

[0039] If the ratio is less than the second threshold, the next main part production schedule is entered. 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, and the ratio of the main part to the accessory is checked again through the accessory dynamic matching module until the ratio of the main part to the accessory meets the first preset ratio, and the next main part production schedule is entered. Through multiple inspections and adjustments, the production ratio of the main part and the accessory is always guaranteed to meet the requirements, which improves the stability and quality of production.

[0040] The production information feedback module monitors the production progress of main parts and accessories in real time. Real-time monitoring of production progress can promptly discover problems and abnormal situations in the production process, provide real-time data support for production management, and facilitate managers to take timely measures to adjust and deal with them, ensuring the smooth implementation of production plans.

[0041] After the main part production plan is completed, actual consumption statistics are conducted, and post-production matching verification is conducted through the verification module. MES modifies the demand release rules based on the post-production matching verification results. Actual consumption statistics and post-production matching verification can summarize the lessons learned in the production process and discover deficiencies in production scheduling management. MES modifies the demand release rules based on the verification results, making production management more scientific and reasonable, continuously optimizing the production process, improving production efficiency and quality, and reducing production costs.

[0042] MES modifies the work order splitting rules based on the post-production matching verification results. Modifying the work order splitting rules can make the work order splitting more in line with the actual production situation, improve the accuracy and feasibility of the production plan, further optimize the production process, and improve production efficiency and resource utilization efficiency.

[0043] On the other hand, 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: ERP, determine the master parts production plan; MES, splits the work orders in the main parts production plan, releases the parts demand to the parts dynamic matching module in batches according to the main parts production progress, obtains the post-production matching verification results and modifies the work order splitting rules; Production information feedback module, real-time monitoring of main parts production progress and accessories production progress and feedback to MES; WMS, to verify the inventory of accessories; The dynamic matching module for accessories can trigger the JIT accessory production line to start production or enter the next main part production schedule based on the matching status of the main part and the accessory. The JIT parts production line replenishes the stock according to the actual matching of the main parts and accessories. Verification module, post-production matching verification.

[0044] The present invention can be applied to the assembly production of large-scale equipment with a main part and multiple types of accessories. For example, in the assembly of an engine, the main part is the engine cylinder block, and the accessories include various transmission parts, spark plugs, studs and other parts. The engine cylinder block is the main part, and the production line of various parts is flexible to meet the actual production needs.

[0045] The present invention can also be applied to the production of small industrial products by assembling a batch of main parts and various types of accessories. For example, in the assembly of a charger, the main parts are the housing and circuit board, and the accessories include various types of resistors, capacitors, diodes and other circuit components. With the housing and circuit board as the main parts, the production line of various components can be flexibly produced to meet the actual production needs.
