Method for reducing switching times of mixed-model assembly line products of automobile

Abstract

The invention belongs to the technical fields of advanced manufacture and information, in particular to a method for reducing switching times of mixed-model assembly line products of an automobile. The method centers the problem that a multi-workshop (or an assembly line) is related and optimized in the production process of complicated products and can be used for reducing the switching times of the mixed-model assembly line products by using an annular buffer area and combining a mixed progressive multi-object genetic algorithm. In the invention, by using the mixed progressive multi-object genetic algorithm, the model production of the mixed-model assembly line of the automobile can be optimally sorted, the material balance of the production line, and the production load balance and the relevant stand of the just-in-time production environment can be considered, so that the model sequence put into production can ensure the smoothness of material consumption, the adjusting time of the model can be shortest and the aim of reducing the switching times of the production line products can be achieved.

Description

technical field [0001] The invention belongs to the field of advanced manufacturing and information technology, and in particular relates to a method for reducing product switching times of an automobile mixed flow assembly line by using a circular buffer zone. technical background [0002] The mixed-flow assembly line is used to assemble multiple products of the same type. Because such an assembly line assembles a large number of products of the same type, the production line needs to switch products according to different product models during assembly. When switching products, corresponding parts and some equipment need to be replaced, which affects At the same time, it is easy to cause mixed assembly of similar parts during the switching process, which affects product quality. Therefore, when assembling the product, the number of product switching should be reduced as much as possible. At present, the production scheduling plan obtained by the production scheduling softw...

[0002] The mixed-flow assembly line is used to assemble multiple products of the same type. Because such an assembly line assembles a large number of products of the same type, the production line needs to switch products according to different product models during assembly. When switching products, corresponding parts and some equipment need to be replaced, which affects Production efficiency, at the same time, it is easy to cause mixed assembly of similar parts during the switching process, which affects product quality. Therefore, during product assembly, the number of product switching times should be reduced as much as possible

At present, the production scheduling plan obtained by the production scheduling software in the mixed-flow assembly line often has problems such as frequent product switching
