Fuzzy multiple criteria decision system for contractor selection

Abstract

Though the construction industry is one of the most dynamic, challenging and rewarding industries, it is also one that is full of uncertainties and associated risks. The proliferation of contracting firms due to low entry barriers to the industry, cutthroat competition as a result of shrinking construction markets in developed and developing countries and the unique nature of construction have led many construction clients to a crucial dilemma and that is which contractor to select for their jobs. As contractors play a pivotal role in any construction project, the crucial task of the selection by the client of ‘the right contractor for the right project’, therefore, constitutes the critical fulcrum upon which the overall success or otherwise of a construction project is precariously balanced.
