Method for rolling computation of material requirement in production management process

Abstract

The invention provides a rolling calculation method of material requirement in a production management process. According to the material requirement schedule of a product, a predicated type is set, the rolling calculation is carried out gradually on the basis that the ordering date is from far to near so as to lead the predicted value to be gradually close to the actual demand value, therefore, the method is used for guiding the purchase and production of enterprises. The detailed steps are as follows: A. a predicated strategy model formed by a predicated strategy number, a strategy name, a starting data, an ending data and attributes of sealing up or not is established; B. a material catalog model formed by a predicated strategy number and other attributes of the material is established; C. a production schedule model formed by a predicated strategy number, schedule states and other attributes of the production schedule is established; and D. an algorithm which is carried out by the material requirement schedule according to the predicated strategy is realized. The invention has the beneficial effects that the result is accurately calculated according to the material requirement schedule; the purchase and production requirements with accurate step-by-step prediction and reasonable product of the enterprise plan are met; and the inventory is reduced, and the turnover rate of funds is improved.

Description

technical field [0001] The invention relates to the technical field of production control, in particular to a method for rolling calculation of product material demand in the production management process. Background technique [0002] When traditional erp management software performs material requirements planning for the products produced, the calculation requires that the planning calculation cycle is longer than the cumulative product lead time. After the planning calculation is completed, the material requirements planning is often changed through net changes or full reassignments. Because The source of products produced by the enterprise and the forecast or sales order, if the material demand planning is carried out entirely on the forecast, the product may not match the actual sales quantity, resulting in a backlog of products. If the production is arranged according to the sales order, the delivery period may be short However, MRP cannot be run to generate purchase r...

[0002] When traditional erp management software performs material requirements planning for the products produced, the calculation requires that the planning calculation cycle is longer than the cumulative product lead time. After the planning calculation is completed, the material requirements planning is often changed through net changes or full reassignments. Because The source of products produced by the enterprise and the forecast or sales order, if the material demand planning is carried out entirely on the forecast, the product may not match the actual sales quantity, resulting in a backlog of products. If the production is arranged according to the sales order, the delivery period may be short However, it is impossible to run material requirements planning to generate purchase requirements and production requirements
