Abstract: 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.
