Simulation Optimization of Equipment Manufacturing System Including Assemble Unit and MHS

定制型装备制造企业采用单元制造系统,单元间物料通过MHS传递。传统数学方法较难获得这类制造系统优化问题的精确解。利用计算机仿真软件构建兼具装配单元及MHS的仿真模型,针对系统中优化变量多、相互间具有耦合作用的特点,采用正交实验的灵敏度分析方法,确定参数优化方向及参数间影响规律,基于优化目标及实际约束条件,提出了一种启发式优化方法。分析表明,提出的优化方法可以有效合理配置企业资源。

Customized equipment manufacturing enterprises use cellular manufacturing system,material handling system transfer material between the units.It is difficult to obtain this type of manufacturing system accurate solution of optimization problem by traditional mathematics methods.The simulation model about process-assemble and material handling system was established based on computer simulation.Because the model has much variable and coupling influence,the sensitivity analysis method was used based on orthogonal experiments,the parameters optimization direction and the influence discipline between parameters were determined,and a heuristic optimization method was proposed based on the optimization goal and practical constraints.The analysis shows that the proposed optimization method can effectively and reasonably allocate enterprise resources.
