基于Flexsim与遗传算法的混流生产线仿真与优化研究

摘要

以某企业汽车后桥生产线为研究对象，运用Flexsim仿真软件建立了混流生产线的仿真模型，对瓶颈问题、生产线平衡等问题进行了优化。同时结合遗传算法以最小化闲置与超载时间为目标，优化了混流生产线的投产序列。使得混流生产线的各项性能指标均得到了提升，同时有效地降低了企业生产成本。证明了运用Flexsim软件与遗传算法相结合，是一种成本较低却效果显著的分析方式。为企业生产线的实际运行提供了理论依据，为优化改进生产线提供了新的方法。%Focusing on a company′s car rear axle production line, simulation model of the mixed-model pro-duction line is built with Flexsim software, the problems such as bottleneck and line balancing are opti-mized. Then, to achieve the target that minimizing idle time and overload time, we use the genetic algo-rithm getting a better production sequence of the mixed-model production line. So that the performance indi-cators of the production line are improved, and the company′s production costs are effectively reduced. Proved that combining Flexsim software and genetic algorithm is a kind of analytical method that are low cost and efficient, it provide a theoretical basis to the actual operation of the production line, and provide a new method to optimize and improve the production line.
