The position and role of the MRP system (material requirements planning) in the production and operation system, the top leaders of the enterprise determine the business strategy and objectives of the enterprise, and determine the business plan for the comprehensive arrangement of the production and operation activities of the enterprise. The annual and quarterly production plans are then determined based on the forecasts and current plant resource conditions. In the process of determining the production plan, a balance of tasks and capabilities is required. This balance is rough and is calculated on the assumption that the product or representative product is the planned unit. The production plan is refined to specific products, and the production quantity and production of each product are clarified, and the product production pre-plan is obtained. When determining the product production pre-planning, it is necessary to balance the rough capacity and then become the production plan. The product production plan in the MRP system (material requirements planning) is different from the usual product production plan of Chinese enterprises. The latter is usually a time unit of the month. The product production schedule in MRP is generally referred to as the main production operation plan in foreign countries. It is the primary input to the MRP system (Material Requirements Planning). The MRP system (material requirements planning) referred to here refers to the basic MRP system (material requirements planning) that only involves material requirements, which is the core part of MRP. In addition to the product production plan, the other two inputs to the MRP system (Material Requirements Planning) are the product structure file and the inventory status file.

After the MRP program is processed, the product production plan is transformed into a self-made production plan and a purchased parts demand plan. The self-contained production plan is a production operation plan that stipulates the time and quantity of input and production of each part constituting the product, so that the production stages can be connected to each other on time. The demand plan for purchased parts specifies the time and quantity required for each purchased component and raw material. A self-contained production plan can calculate the capacity needs for each job site to arrive at a capacity demand plan. If the production capacity is not fully utilized or the load exceeds the capacity, adjustment measures can be taken, such as overtime work, adjustment of manpower and equipment, and transfer of foreign companies. If the adjustment does not work, the information is fed back to the production product planning module to make adjustments to the plan. When the tasks and abilities are basically balanced, each workshop can prepare the workshop production operation plan according to the self-made parts. The implementation of the workshop production operation plan shall pass the statistics of the workshop operation. From the statistics, the actual deviation from the plan is found, and the deviation is corrected by modifying the plan or scheduling method to implement production control. Feedback from actual production can be used to adjust the shop's production schedule and capacity requirements plan to make the plan more responsive.

Orders are submitted to the supplier on time according to the purchased parts demand plan. After the order is made, the information is continuously obtained from the supplier, and together with the completion information of the parts in the production process, it is sent to the inventory status file.
