Risk Evaluation of a Construction Building Using a Hybrid Approach

Abstract

This chapter aims basically to ensure two benefits, which focus on method and application. Firstly, this chapter proposes a new approach, which is TOPSIS (technique for order preference by similarity to ideal solution) based on interval type-2 trapezoidal fuzzy (IT2TrF) numbers. Secondly, the proposed method is applied to failure mode and effects analysis (FMEA) problem to overcome the drawbacks of traditional FMEA, which determines possible failure modes. In traditional FMEA, the risk priority number method, which is obtained as the product of occurrence, severity, and detection risk factors, has been debated to have several drawbacks. The implementation of risk assessment is realized to indicate the validity of the suggested approach in a construction building. The results of the proposed approach and some other methods are compared. The aim and resources are optimized by using linear programming.
