Description of the invention (2) —: The enterprise resource planning (ERP) system is used for material requirement planning and manufacturing resource planning. However, the material planning and production planning described above assume materials. The supply and production line capacity ^ is unlimited, and the relevant schedule planning of the order is performed. Because unlimited = material supply and production line capacity are deviated from the actual situation, planning by mistake ^ = will definitely cause delay in the order. Please refer to the schematic diagram of the production schedule planning. The horizontal axis represents the maximum production capacity of the factory with sufficient material supply. When A ^ orders A, B, and C, for the order a and old, i six Γ / industry connection Zhang booked. a, ° The parent period (duedate) is ί ^-夂 pay / door early feed tearing time is Tl, so order A can arrange its delivery time to be T2 and take ^ for ordering, if order B can Scheduled at TH2, the time between them is T3. If order c is obtained, for order C, its C can be scheduled to be produced between T3 and T3, 4 because the time is T3, the order The order B2 of the soap B is delivered, and the parent B of the order B is earlier than the delivery time T3 of the order B. Therefore, the order of the order is A, and the order g is earlier than the order C. The maximum capacity of the actual production line is B / order C. However, due to the use of *, the conventional technology does not consider ^ grade Dingbu n, which accounts for a reasonable schedule, so when the order β is intended to be carried out through capacity allocation, it will be carried out because there is no available capacity. When the product is manufactured, the order ... Production will also be affected by (3) 573270. Knowing companies will manually plan the system and influence the production order between production orders, because the supply of materials that may not be easy to make is directly applied through the knowledge Each is prone to errors, knowing the enterprise resources and unfinished answers to the enterprise's mistakes. 5. Inventive explanation questions. At this time, I have multiple adjustments to the schedule of the enterprise resource line based on experience, but it is time consuming and has limited additions. Therefore, planning can not be laborious and time-consuming, and it will cause learning list materials. It is expected that the invention will outline the resource planning to adjust the occurrence of the problem. The mutual influence cannot show that this is only based on the best conditions. The technology must be calculated in addition to, Wrong planning system Material purchase judgment The operator of the current system has a problem with the ordering of the operator. This operator will still cause problems. After an order is adjusted, the operator plans the manual production schedule, which will make the materials drawn in the foregoing schedule. The material planning and manual adjustment of manual material planning and § have recorded a large amount of uncompleted order data, etc., errors in the shipping status must be based on this process. If the revision is performed at the same time, however, it is known that the entire production mode is not adjusted. In addition, if The readjustment is more reorganized and the production is more regular, and not only the customers who have spent more time on production planning have formulated incorrect incorrect decisions. Therefore, the main purpose of ★ & its research is to provide a constraining system for planning and scheduling. The main purpose of the invention is to solve the above problems ^. Multiple restrictions on materials, production capacity, etc. The planning schedule of the invention ^ It is clear that the patent patent provides a computer system planning-manufacturing device 1 and scheduling method.

Description of the invention (12) The main cause of the delay in delivery is the material or capacity. If it is the delay caused by the material, you can use alternative materials or suppliers to improve the quantity and time of the material supply. If the delay is caused by capacity, you can use an alternative process (such as another production line) or increase production hours to improve the problem of insufficient capacity. If the delay caused by the order is caused by materials and capacity, use all of the above possibilities. The combination until the delay time is shortened and settled ^ is A. Please note that the above-mentioned method of reducing order delays ^ corresponds to-the predefined priority order, for example, to solve the delay in delivery due to materials and production month b The method has a total of M, A2, A3, A4, A5, A6 according to the priority order. Therefore, the order optimization process will first use "and f from steps 104 to 108 to determine whether the order delay time is coincident; the single delay time is not less than this. A predetermined threshold, the ^ early optimization process will additionally use A2 and go through steps 104 to 108 to determine whether the second delay time is less than the predetermined threshold , #At this time, the j is less than the predetermined threshold when the order is delayed, indicating that the order optimization process has been completed, because ~ " I was widely used by the order optimization process, and then use the step to accept the order optimization process The result is to update the schedule plan by one and two, and then when the order is delayed, ^ 12 to adjust the multi-level bill of materials.

This must be required material planning can be applied to capacity planning, to determine the relevant factory If you can, you can decide the same limit to plan the material limit first, and start the production method after all the materials are available. You can also consider the capacity limit to the industry that focuses on capacity planning. The utilization rate is a priority, so the use of factory machinery is improved. Determine the required materials, and pass a material time limit. For example, for the capacity planning of each order, you can get the required quantity of the material and when the material needs to be fed. Regarding the order in which the conditions are considered, it is planned first. However, 'then the test, for example, the semiconductor must first make the target, and then the material is limited.' First, according to the production, so for each, then you can do this, different production plans to meet the consideration of the material industry, and the capacity limit can be limited based on the availability. Demand is based on property.
