复杂产品设计决策中耦合因素处理的简便方法
The simple method to deal with the coupling factors in complex product design

对复杂产品设计决策中耦合因素进行分析，并利用已有的响应面法对耦合因素进行处理. 鉴于理想响应面的建立需要大量计算与迭代，而且精度受拟合函数影响，给出一种基于鲁棒思想的耦合因素处理方法. 其既可有效降低学科间的相互影响和耦合程度，又可保证满意的设计决策结果，计算简便. 最后以汽车盘式制动器的设计决策为例进行分析，并将两种方法的结果进行对比，表明了本文方法的可行性和有效性.
Analyzes the coupling factors in the complex product design decisions，using the existing response surface method to deal with coupling factors. In view of the establishing of ideal response surface needs a large number of calculation and iteration，and the accuracy are influenced by fitting function，a simple and effective method to process coupling factors based on robust ideas is given，which not only can effectively reduce the mutual influence and the coupling degree between disciplines，but also can ensure the satisfying results of design decisions. Finally，a car disc brake design decisions is given as an example，which shows the feasibility and effectiveness of the method presented in this paper by comparing the results of two methods
