基于分位数型设计准则的模糊健壮设计新方法

在模糊目标和模糊设计约束的条件下，同时考虑了质量特性的健壮性和设计约束的可行健壮性，提出望目特性、望大特性和望小特性模糊健壮设计的分位数型设计准则。在该设计准则的基础上，建立不同类型质量特性的模糊健壮设计优化模型，并将常规优化算法和基于最大可能点的分位数求解算法相结合构成该模型的求解框架。最后通过实例验证了该方法的有效性。

NEW METHOD FOR FUZZY ROBUST DESIGN BASED ON PERCENTILE FORMULATION DESIGN RULES

Under the conditions of fuzzy objective and fuzzy design constraints, the percentile formulation design rules for fuzzy robust design, which brings both the robustness of quality characteristic and the feasibility robustness of design constraints into account, are proposed when the product quality possesses nominal-the-best or larger-the-better or smaller-the-better characteristic. The optimal model of fuzzy robust designed with different types of quality characteristic is presented based on the proposed rules. A framework for solving the presented model, which combines the general optimal algorithm with the most probable point based percentile search algorithm, is also proposed. A case study is described to show the effectiveness of the proposed approach.
