Problems solved by technology

The material substitution method in the traditional material requirements planning system is that when material substitution is required, all BOM subitems that use the substituted material will be substituted, and it is impossible to specify a subitem to be substituted
In addition, when the available inventory of a substitute material cannot satisfy the substitution demand of all sub-item items, the sub-item that cannot satisfy the most substitutable needs to be substituted occurs
Therefore, the availability of material substitution methods in traditional MRP systems is not high

Embodiment Construction

[0044] figure 1 The flow of the material substitution method in the material requirements planning system in an embodiment is shown, and the flow of the method includes the following steps:

[0045] Step S102, read parent item material information, child item material information and substitution relationship information.

[0046] Step S104, obtaining the net requirement of the child item material according to the parent item material information and the child item material information.

[0047] Step S106, judge whether the available inventory of the sub-item material is zero according to the net demand of the sub-item material, if yes, go to step S108, otherwise end.

[0048] Step S108 , according to the substitution relationship information, search for substitute materials of the sub-item materials, and sequentially replace the sub-item materials with substitute materials whose available inventory is not zero according to the substitution relationship information.

Abstract

The invention provides a material substitution method in a material requirement planning system. The method comprises the following steps of: reading the parent item material information, the child item material information and the substitution relation information; obtaining the net requirements of the child item material according to the parent item material information and child item material information; judging whether the available inventory of the child item material is zero according to the net requirements of the child item material; and if the available inventory of the child item material is zero, searching for a substitution material of the child item material according to the substitution relation information, and substituting the substitution material of which the available inventory is not zero for the child item material according to the substitution relation information. Through the method, the material substitution for the designated child item can be realized, and the availability of the system is improved. Moreover, the invention also provides a material substitution device in a material requirement planning system.

Description

【Technical field】 [0001] The invention relates to data processing technology, in particular to a material replacement method and device in a material demand planning system, and a material demand planning system. 【Background technique】 [0002] In product manufacturing enterprises, in order to supply the products required by customers or market demand on time without causing inventory backlog, Material Requirement Planning (MRP) is required. MRP is a material planning management mode in a product manufacturing enterprise. It 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 date as the time basis to reverse the plan, according to the length of the lead time Distinguish the sequence of the release plan time of each material. [0003] A basic data source of MRP is the bill of material (Bill of Material, referred to as "BOM"). The BOM lists all the constituent ...
