Business model based on PERT core ERP (MRPII)

Abstract

The invention discloses a business model based on PERT core ERP (MRPII), and the method comprises the steps: carrying out the main production plan: predicting the order quantity according to the customer order quantity or market, combining with the existing stock and formulated order quantity, and systematically calculating the variety and number of products needing to be produced by an enterprise; generating a plan network according to residual order amount: according to the main production plan and the product BOM table, generating corresponding production orders and purchasing orders in combination with existing periods needed by formulated orders, inventory and customer orders, establishing supply and demand relations between the orders and between the orders and the inventory, and forming a plan network graph; the planning network diagram can be correspondingly evolved along with operations such as batching and completion of orders. The ERP system provided by the scheme of the invention not only can be applied to a mass production mode, but also can be applied to a single-piece small-batch mode or a customized production mode.

Description

technical field [0001] The invention relates to the technical field of processing and manufacturing, in particular to a PERT-based core ERP (MRPII) business model. Background technique [0002] Material Requirement Planning (MRP) means that according to the subordination and quantity relationship of items at each level of the product structure, each item is planned as the planning object, and the completion period is used as the time basis to reverse the plan, and each item is distinguished according to the length of the lead time. The order in which plans are released is a material planning management model in industrial manufacturing enterprises. 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 proce...

Problems solved by technology

[0010] The purpose of the present invention is to provide a kind of business model based on PERT core ERP (MRPII), possess not only can apply mass production mode, also can apply the advantage of single small batch mode or customized production mode, solve the ERP based on MRP core ( The MRPII) system can only solve the production problems of enterprises with few varieties, large batches and relatively stable production status, and cannot cope with single-piece, small-batch and customized enterprises, especially the production mode of large-scale equipment. The production mode has changed from large-scale to large-scale Today, when production is shifting to single piece small batch production and customized production mode, the ERP (MRPII) production management system based on MRP core has become a bottleneck problem restricting the development of enterprises
