Abstract |
The production engineer’s decision regarding buffer size in a flexible production system is one of the most important factors in maximizing production efficiency. In this paper, we propose a model Flexible Production System with Sub-lines (FPSS). By using the model, we can find the buffer size of FPSS by using GA. Also, we propose a new GA expression, referred to as a Matrix Encoding Method (MEM). This paper deals with an FPSS which consists of 5 main component lines, i.e. a main production line, parallel lines, rework path, feed-forward line and feeder line. Numerical examples show that after a number of operations based on the GA with MEM expression, the nearest optimal buffer size of FPSS could be found. The results of this study can be used to improve the production plant, and production engineers can use these results in their decisions on buffer size when they develop FPSS. |
