Abstract

The purpose of this study is to enable consistency control along with expert consistency prioritization for direct fuzzy inputs as basic events (BEs) assigned to the fault tree analysis (FTA) method. In the recent literature, fuzzy fault tree analysis (FFTA) applications have no consistency check for the expert judgments. In this study, as a multi criteria decision making method, fuzzy analytic hierarchy process (FAHP) is applied for checking the consistency by centric consistency index (CCI). Expert consistency prioritization is also implemented for FFTA by using extent analysis method of trapezoidal FAHP. An analytic comparison between with and without consistency control is obtained. The numerical results for collapse of an offshore platform are presented to illustrate the applicability of the approach. (C) 2017 Elsevier B.V. All rights reserved.
