APPLICATION OF MULTI-CRITERIA DECISION MAKING TECHNIQUES FOR BRIDGE CONSTRUCTION

Abstract

In various stages of project lifecycle, decision making has vital and strategic importance. These decisions are related to different problems and one of the issues is related to selection of alternatives. Decisions made must be independent of any preference or influence. Improper or incorrect selections often increase duration and expenditure of project. The conventional methods for decision making are inadequate for dealing with the imprecise or vague nature of today‟s complex decision problems. To overcome this difficulty, in this paper use of fuzzy Multi-Criteria Decision Making (MCDM) methods is discussed. The aim of this study is to use fuzzy Analytic Hierarchy Process (AHP) and the fuzzy Technique for Order Preference by Similarity to Ideal Solution (TOPSIS) methods for the selection of type of bridge. The proposed methods have been applied to selection of bridge type problem in Pune city. After determining the criteria that affect the selection of type of bridge decisions, fuzzy AHP and fuzzy TOPSIS methods are applied to the problem and results are presented. The similarities and differences of two methods are also discussed.
