Material demand distribution method, device and system and storage medium

Abstract

The invention relates to a material demand distribution method, device and system and a storage medium. The method comprises the steps: executing a single material demand supply balance algorithm for materials of a non-alternative material group, and obtaining the demand distribution amount of each material in the non-alternative material group; for the materials in the substitute material group, calculating the demand distribution priority of each material in the substitute material group, and determining the material demand distribution amount of each material in the substitute material group according to the demand distribution priority; using a standard MRP algorithm to perform demand distribution on the materials of the substitute material group by adopting a material demand distribution amount and a material demand distribution sequence obtained by MRP pre-calculation; and carrying out material distribution on the materials of the non-alternative material group according to single material demand supply balance, realizing supply and demand balance adjustment of all the materials in the bill of materials, and obtaining material demand plan information of the production task product.

Description

technical field [0001] The invention relates to a material demand distribution method, device, system and storage medium, and belongs to the technical field of computers. Background technique [0002] Material Requirement Planning (MRP) refers to the network support plan and time schedule plan for all manufactured parts and all purchased parts required for each project of the master production plan (MPS). MRP is to formulate a product production plan based on market demand forecasts and customer orders, and then generate a schedule based on the product to form a material structure table and inventory status of the product, and calculate the demand and demand time of the required materials through the computer to determine the processing of the material A practical technique for scheduling and ordering schedules. The key information involved in the MRP operation includes: [0003] Master Production Schedule (MPS), Material Requirements Planning is driven by MPS. It indicat...

Problems solved by technology

[0007] After the generation of alternative materials, the BOM of the product becomes more complex, which increases the complexity of material demand calculation. The standard MRP algorithm uses LLC (Low Level Code, material low-level code) to expand the BOM layer by layer from top to bottom. In the process, if a substitute material group is encountered, the standard MRP only considers the current supply quantity of each material in the substitute material group of the current layer, and does not consider the supply status of the next layer of the current material (manufactured part or semi-finished product). Therefore, The standard MRP calculation method is difficult to accurately deal with the material procurement requirements in the scenario where alternative materials exist, and it is difficult to achieve the balance between supply and demand of materials
