基于物理规划的模糊稳健优化设计

Fuzzy robust design optimization based on physical programming

为了改进提高产品性能稳健性的工程设计方法,将稳健设计中的容差和所要达到的优质品率作为两个目标函数,建立了模糊稳健双目标优化设计模型,并应用物理规划方法进行求解。通过对齿轮传动装置装配尺寸链的稳健优化设计,给出了具体的分析求解过程。实例表明,该文所提出的方法是可行的。

A design method was developed for high quality, high performance products using a fuzzy robust design and bi-objective optimization model. The bi-objective functions are the tolerance of performance and the probability of high system quality. The model was solved using physical programming. A numerical example to optimize the dimensions of a gear assembly chain illustrates the solution progress and the model performance.
