基于响应面方法的航空发动机装配系统的多目标性能优化

Multi-objective Performance Optimization of Aircraft Engine Assembly System Based on Response Surface Methodology

将响应面方法应用于复杂的航空发动机装配生产系统的性能优化中,获取系统的最大平均生产率和最小在制品水平,并解决以平均生产率和在制品水平为目标函数,以系统单机加工速度和缓冲区总大小为决策变量进行多目标性能优化问题。解决多目标优化问题的方法是利用线性加权法将多目标转换为单目标,然后应用响应面方法进行优化。实验结果表明:响应面方法能够很好地解决复杂的航空发动机装配生产线的性能优化问题,并为决策者提供多种情况下的最优解。

Response surface methodology （RSM） is applied to the performance optimization design of a complicated aircraft en- gine assembly system to maximize the average throughput and minimize the work-in-process （WlP） level,and then it is used to solve the multi-objective performance optimization problem which takes the average throughput and WlP level as objectives,and takes the product rate of a single machine and the total buffer size as the decision variables.This paper em- ploy the weighted sum method to convert the multiple objectives to a single objective and then apply the RSM to solve the single objective optimization problem.
