Abstract

The invention relates to the field of engineering manufacture, in particular to an optimal design method for production line layout. The technical problem that the influence of production fluctuation on production efficiency cannot be reduced by the conventional method so as to reduce enterprise benefits is solved. According to the scheme, the optimal design method for new production line layout mainly comprises the following steps of: acquiring the labor house data of original sub-procedures; generating functional segments and a station number by adopting a line balancing planning method, so that the cycle time of a single line in each functional segment is shortest; when total investment C is determined, finding all N and S combinations consistent with a constraint condition by using an enumeration method; calculating the cycle time of each functional segment; calculating the overall cycle time of each [N, S] scheme; and performing calculation according to the steps, and when the total investment C is determined, determining a scheme with the shortest cycle time in all the [N, S] schemes as a target scheme. The method can be used for the design of the new production line layout and the modification of the conventional production line layout.

Description

technical field [0001] The invention relates to the field of engineering manufacturing, in particular to a production line layout optimization design method. Background technique [0002] In order to improve production efficiency or reduce staff and increase efficiency, in the field of manufacturing and processing, the layout of the workshop production line is often redesigned according to the economic resources invested and the order volume to be completed, and the production line is modified and optimized. The layout of the production line mainly includes the relationship between each functional section, the relationship between sub-lines in each section, and the arrangement of stations inside each sub-line. In the field of manufacturing and processing, there are several common layout methods for production lines, stations, and processes in the production system. For example, in the layout of large-scale manufacturing assembly lines, each station corresponds to a relativel...
