[[alternative]]Robust Feasible .alpha.-cut Method for Optimum Engineering Design

[[abstract]]一般所認知的合理穩健模糊最佳化題目的設計解，經由本文的研究，得知為趨向保守的唯一解。當模糊限制函數含有模糊允許值及模糊參數時，本文根據標準α切模式發展了重建限制歸屬函數及α切穩健模糊演算法。由結構設計例顯示，本文之α切穩健最佳化方法比一般認知的解法更為合理，也得到更佳的設計目標。[[abstract]]The general recognized feasible robust fuzzy optimization is conservative unique design, as studied in this paper. When a problem contains fuzzy allowable value and fuzzy parameters in the constrained functions, this paper rebuilt the membership functions on the basis of typical .alpha.-cut strategy to develop a new .alpha.-cut feasible robust optimization approach. A structural engineering .alpha .-cut design problem is given herein for illustrating the presenting method with the feasible robustness. The final result of the presenting robust feasible .alpha.-cut method is better than that of the general robust method.[[sponsorship]]交通大學; 中國模糊學會; 國科會工程處工程科技推展中心[[notice]]補正完畢[[conferencetype]]國內[[conferencedate]]20021205~20021206[[booktype]]紙本[[iscallforpapers]]Y[[conferencelocation]]新北市, 臺
