Material information modifying method and material information modifying device in material demand plan system

Abstract

The invention is applicable to the field of resource management, which provides a material information modifying method, a material information modifying device and resource management equipment in amaterial demand plan system. The material modifying method comprises the following steps: sequentially detecting the net demand of all materials; when detecting that the net demand of any material isnot zero, searching a substitute material corresponding to a substituted material, the net demand of which is not zero, according to substitute relationship information and the usable material storagerate; and modifying the net demand of the substituted material and a relevant interior material and the searched usable storage rate of the substitute material according to a bill of material information of the substituted material, substitution ratio information and the searched usable storage rate of the substitute material. In the embodiment of the invention, the provided material informationmodifying method has the advantages of short processing time, high efficiency, high accuracy and thorough substitution.

Description

technical field [0001] The invention belongs to the field of resource management, and in particular relates to a method and device for modifying material information in a material demand planning system, a material demand planning system and resource management equipment. Background technique [0002] A product can list all the constituent materials constituting the product and their affiliation and demand quantity through the product structure. The structure of a product can be represented by files with standardized data formats such as structure trees and structure tables. In the files, the materials constituting the product, their required quantities, and their structural relationship must be stated. Such files are called materials. Bill of Material (BOM). [0003] Material Requirement Planning (MRP) refers to the subordination and quantity relationship of materials at each level of the product structure, with each product as the planning object, and the completion perio...

AI Technical Summary

Problems solved by technology

The existing material information modification method does not use an automated material requirement planning system to modify material information, which takes a long time to process, is inefficient, and is prone to errors. In addition, when the material affiliation of the product is complex, the replacement may not be complete.
