    摘要: 本研究承接上年度之研究計畫,繼續發展回應表面近似法的工程最佳化設計研究,特別適用於需有限元素分析之大型結構設計。本研究的重點方向在於用最少的實驗點數目建構隱函數式的對應回應表面顯函數,以達到解含允許模糊值問題的目的。另一類型主題是用回應表面技術發展求解另含模糊參數及模糊變數的結構最佳設計問題。在處理第二類型問題上,基本上採用了處理顯性函數問題的觀念及技術,將數學形式轉換為第一類型後再發展回應表面法處理方法技術。由於第二類型題目複雜度相對提高,在此僅以中型之結構設計為例,作為研究發展的模型,加以解說與討論。其設計程序及技術可直接應用於大型規格之結構最佳設計分析及其他工程設計題目。
    This research extends the last year's project and continuous to develop the fuzzy optimization process and technique using the response surface methodology. The first significant target is the use of least number of experimental points to construct the approximate response surface in optimization process for the problem contains allowable fuzzy number. The second primary research topic is to develop the solution method for dealing with both fuzzy variables and fuzzy parameters simultaneously exists in objective or/and constrained functions. For attacking the second type of problem by response surface method is particularly complicated because it requires transform the original fuzzy functions to the ordinary allowable fuzzy number problem. In the further work, one needs to pay a lot of attention to how to solve the problem to meet the required feasibility, robustness and optimum result. Since the problem itself and the solution method are relative difficult, as compare a general allowable fuzzy number problem, therefore, an example with middle degree of complication is adopted here for the illustration to the presented integrated design process.
