Abstract

The invention belongs to the technical field of production scheduling, and relates to a method and device for scheduling production. The method comprises the steps that: the order information of various types of products, the information of materials needed by the production of the various types of products, and the capacity information of each production line are obtained; based on the order information of the various products, the material information and the capacity information of the production lines, a production scheduling mathematical model is constructed, wherein the production scheduling mathematical model comprises decision variables, constraint conditions and an objective function; based on the decision variables, the constraint conditions and the objective function, the valueof each decision variable is obtained when the objective function value is minimum; and based on the value of each decision variable, a production scheduling plan table is obtained, so that a production scheduling scheme can be quickly obtained, and the production line efficiency is improved.

Description

technical field [0001] The invention relates to the technical field of production scheduling, in particular to a method and device for scheduling production. Background technique [0002] At present, my country's economy is developing rapidly, and the demand for diversified commodities is also increasing. The manufacturing industry is facing huge challenges. With the increase in orders and product types, how to arrange the production of factories has become particularly important. In the production schedule At present, it is necessary to reduce the delay of orders as much as possible without frequent switching of product types, and the result directly affects the production efficiency of the factory and customer satisfaction. [0003] The existing production scheduling plan is often formulated through manual experience, which is inefficient and may cause a waste of a large amount of production capacity of the factory. [0004] Therefore, how to quickly obtain a better produc...
