This paper is talking about the optimization of production lines by Flexsim, based on Chinese national condition, development needs of industry. Recombine the technical advantages home and abroad for achieve the best purpose. This paper focuses on the use of industrial engineering method、 mathematical analysis method and heuristic method in production line optimization and also introduced a genetic algorithm method . At last with the compatibility of Flexsim , we can seek more ways of simulation result. If it is not very satisfactory then return to various algorithms to get the data improve. With such cycle of continuous improvement we can achieve the objective of improving.
KEYWORDS: Flexsim、 genetic algorithms、 heuristic method、production line
