Bridge Risk Assessment using Integrated Failure Mode, Effects, and Criticality Analysis and VIKOR Approach

Abstract

The high probability of failure of concrete bridges due to their deterioration over time necessitates the implementation of risk assessment tools. One risk assessment tool that has been applied extensively and proven to be effective is the failure mode, effects, and criticality analysis (FMECA). The purpose of FMECA is to determine and assess all possible failure modes and analyze their causes and effects in order to eliminate them before they can occur. The application of FMECA in construction and infrastructure industries, in general, is limited. Therefore, the aim of this paper is to build a framework for implementing FMECA in bridge risk assessment in combination with the VIKOR (VlseKriterijumska Optimizcija I Kaompromisno Resenje in Serbian) method to avoid the problems associated with the traditional FMECA method. The aim of the proposed model is to serve as a guide for ranking and prioritizing failure modes of concrete bridges under a fuzzy environment.
