选择最佳加工条件的问题，其中配方涉及使用的经验关系，被认为是。由于随机性和模糊性都与经验关系有关，因此提出了一个耦合不确定性模型来操纵这些不确定性。方程推导出建立两种类型的不确定性之间的相互关系存在于目标函数和约束的优化过程。这允许系统地处理通常与实验相关的随机性方面的模糊性。该方法的计算方面说明了两个数值例子处理加工过程的优化。
The problem of selecting optimal machining conditions, where the formulation involves the use of empirical relations, is considered. Since both randomness and fuzziness are associated with empirical relations, a coupled uncertainty model is proposed for manipulating these uncertainties. Equations are derived to establish the interrelation between the two types of uncertainties present in the objective functions and constraints of the optimization process. This permits a systematic handling of fuzziness in terms of randomness that is usually associated with experiments. The computational aspects of the approach are illustrated by two numerical examples dealing with the optimization of machining processes.
