Development of risk index for mass rapid transit system project in Western India through application of fuzzy analytical hierarchy process (FAHP)

Mass rapid transit system projects like elevated corridor metro rail construction involves activities like segment casting, segment transportation and segment erection that are extremely risky in nature and need to be implemented very carefully. This article is an attempt to develop risk index for the elevated corridor metro rail construction project in Western India. The risk index is created by application of fuzzy analytical hierarchy process to the quality parameters associated with the segment casting, piling work, pier construction, segment transportation, segment erection with launching girder, jointing of segments and pre-stressing operations. This risk index would help the project authorities associated with ongoing and upcoming metro rail projects to identify and categorize the most risky activities and plan suitable risk mitigation measures accordingly. This would help the metro rail project to be completed successfully within stipulated time and cost frame.
