Prequalification of Construction Contractor using a FAHP

Abstract

Analytical hierarchy process (AHP) as multiple criteria decision making tools can be used in the problems with spatial nature like selection of construction contractor. In this study the application of AHP and its weakness and strength and ultimately the fuzzy modified analytical hierarchy process (FAHP) is proposed after the concept of fuzziness, uncertainty and vagueness. A triangular fuzzy umber is considered to form a fuzzy comparison matrix for criteria and alternatives (contractors). Consequently a fuzzy score matrix is prepared to obtained crisp score (defuzzified value), which ultimately gives overall ratting of the alternatives (contractors). The construction industry is an integral part of infrastructural development of country. The selection of appropriate construction contractor is the multi criteria decision making process. In the large project it is very difficult for the decision makers to analyze the capabilities of contractors against vagueness, imprecision, inexact and qualitative criteria. These criteria can be best expressed in the linguistic terms, which cab be translated into mathematical measures by using multi criteria decision making techniques (AHP and FSM). In this paper, we present an effort to provide application of fuzzy analytical hierarchy process in the selection of contractor. To develop a fuzzy analytical hierarchy approach to rank the suitable contractor for the housing project.
