Method for steel production contract plan and multi-level inventory matching optimization under MTO-MTS management mode

Abstract

The invention belongs to the field of management science and engineering and particularly relates to a steel production contract plan compilation method based on multi-level inventory matching under an MTO-MTS mixed production mode. A logical frame of the method is composed of five modules which are a contract pool establishing module, a multi-level inventory matching module, a multi-process production plan module, an inventory and production collaboration module and a human-computer interaction and evaluation module, wherein the inventory and production collaboration module is a system core, a multi-level inventory and production plan joint optimization algorithm based on a rematch collaboration strategy is adopted for the inventory and production collaboration module, and the contract plan compilation problem under a mixed mode is solved by being combined with parameters coming from the human-computer interaction and evaluation module and coordinating the multi-level inventory matching module and the multi-process production plan module according to the output of the contract pool establishing module. The method is based on an operational research model and an intelligent algorithm, is the contract plan compilation method based on multi-level inventory matching and has important theoretical significance and wide application values for improving flexibility of a steel enterprise production management system.

Description

technical field [0001] The invention belongs to the field of management science and engineering, relates to the application of operations research modeling and intelligent optimization algorithms, and in particular relates to a contract planning method for iron and steel enterprises based on multi-level inventory matching in a mixed process production mode. Background technique [0002] With the development of information technology, the production management level of most domestic iron and steel enterprises has been greatly improved, but the drafting of contract plans is still at a relatively backward level. During the planned economy, most enterprises adopt MTS (Make to Stock), an inventory-oriented preparation method. According to the distribution of remaining inventory and on the basis of inventory matching, they arrange production for unmatched contracts. In order to meet order demand factors such as contract delivery date, customer importance, contract steel grade, and...

Problems solved by technology

[0004] 1. Failure to reasonably coordinate the contradiction between product customization and rapid production response from a global perspective;

[0005] 2. Failure to give full play to the remaining inventory, especially the impact of semi-finished product inventory on the production plan in the current planning outlook period, greatly restricting the flexibility of contract planning;

[0006] 3. When arranging the production plan according to the production capacity of the unit, there is a lack of consideration for the balance of production capacity

However, the above research is only based on the joint optimization of production and inventory based on finished product inventory matching, without considering the coordination effect of semi-finished product inventory on pro
