Abstract

The invention provides a multi-product mass production planning method and system. The method comprises the steps that multi-product mass production planning is converted into multiple pieces of single product mass production planning with a lagrangean relaxation algorithm; the multiple pieces of single product mass production planning is calculated with a dynamic planning algorithm, and whether target multi-product mass production planning obtained by combining calculated multiple pieces of single product mass production planning meets preset constraint conditions or not is judged; if not, the target multi-product mass production planning is adjusted with a greedy heuristic algorithm to make the target multi-product mass production planning meet the preset constraint conditions. The total production cost is minimized on the premise that multi-product mass production is completed.

Description

technical field [0001] The invention relates to the technical field of product production planning, in particular to a multi-product batch production planning method and system. Background technique [0002] The economic batch problem generally describes such a type of problem. It is known that the demand for a certain product or a certain type of product in a given cycle in the planning period can be obtained through a combination of current cycle production, previous cycle inventory, delayed delivery, or outsourcing. Satisfy. In each cycle, the cost functions of production, inventory, outsourcing, and backorders are known, and the quantities of production, inventory, outsourcing, and backorders may be limited. The goal is to meet the dynamic demand during the planning period with the minimum cost, and the production plan obtained at this time is the optimal production plan. [0003] According to different actual situations, the economic batch model to be studied is diffe...
