Description

In this study, we will improve production by reviewing the production line. In order to realize improvement, we will develop a system to decide the layout of assembly production line, with several workers involved. In this study, we define this system as System of Production-line-layout Decision by Chameleon-code and Genetic Algorithm (PDCG). PDCG decides a layout of production line using GA and work-flow-line acquired from Chameleon code and machine failure data. Specifically, PDCG calculates and evaluates the worker's walking time for repair of the machine failure generated in production line from the line layout operated by one worker per line. Then PDCG decides the good layout which operates multiple production lines with one worker. We compared the layout obtained by PDCG with parallel layout. As a result, PDCG layout reduced walking time by about 63 minutes from parallel layout. Therefore, PDCG is effective for layout arrangement in which one worker manages multiple production lines.
