Adaptive material requirement plan (MRP) calculation method

Abstract

The invention discloses an adaptive material requirement plan (MRP) calculation method. The method comprises steps: a material list is acquired; lowlevel codes of all materials in the material list are calculated; sales orders in need of calculation are selected; according to conditions that the lowlevel codes and the material codes are ranked from low to high and the MRP type is equal to a requirement type, traverse calculation is carried out on MRP table records, and a production or procurement plan on the materials is generated; and automatic delivery date adjustment is carried out on all orders which participate in MRP calculation and need to automatically adjust the delivery dates. Delivery date adjustment can be automatically carried out on orders, whose delivery dates can not be met, and the generated plans, the process comprises steps in which the delivery dates of the sales orders are properly adjusted automatically, and the plan starting dates and the plan ending dates for a production order and a procurement order related to the sales order can be automatically adjusted, system flexibility is improved, and management by a manager is facilitated.

Description

technical field [0001] The invention relates to the technical field of production and manufacturing management, in particular to an adaptive material demand planning calculation method. Background technique [0002] For manufacturing enterprises, production is the lifeline of the enterprise. However, such problems often occur in the production line: when the sales department signs the sales order, the production department cannot arrange production; and once the production is arranged, the supply department has no time to purchase Materials; at the same time, there is often a shortage of materials used in production in the warehouse, while there is a long-term backlog of useless materials. [0003] The main reason for this problem is that there is no reasonable production plan, and the production, supply and marketing are seriously out of touch. If the three problems of what materials should be produced, when to produce, and how much to produce can be solved, the goal of "n...

Problems solved by technology

[0002] For manufacturing enterprises, production is the lifeline of the enterprise. However, such problems often occur in the production line: when the sales department signs the sales order, the production department cannot arrange production; and once the production is arranged, the supply department has no time to purchase At the same time, there is often a shortage of materials used in production in the warehouse, while there is a large backlog of useless materials for a long time

Although ERP systems at home and abroad have made some achievements in the research of customizing MRP, the existing MRP systems have a large amount of calculation, low efficiency, and cannot track the calculation process of MRP, often only see the calculation results, but it is not easy for users understand how this result was obtained
