| Summary: | 碩士 === 南開科技大學 === 車輛與機電產業研究所 === 107 === The reliability allocation method is used for the sub-level systems of product which should be allocated down the reliability objective during the initial development phase. After selecting and comparing the necessary estimated parameters of the sub-level systems, the weighing values will be determined from the experts. To reduce the cost of reliability works for the new product development program, selecting applicable reliability allocation method has become important work.
This study adopts the fuzzy Delphi method (FDM) and Fuzzy Analytical Hierarchy Process (FAHP) to establish two reliability allocated models for the vehicle system. The first proposed FDM model is more objective than the Feasibility-of-objectives method. Instead of giving the points directly with the Linguistic variables. The second proposed Fuzzy AHP model is more simple and easy than the Thurstone-Mosteller allocation method. Instead of mass computations with the Fuzzy computation. Besides, the proposed two models adopt the consistency analytic procedure to confirm the accuracy of weighting values estimated by the experts.
We build up the analytic procedure of proposed FDM and FAHP two models successfully. The Experimental results suggests the estimated parameters of weighting values for the reliability allocation in vehicle system and they can be useful in other field product applications.
