Selection of Appropriate Construction for Mass Rapid Transit Project by AHP and Ranking Method

Abstract

Nowadays, there is no appropriate criteria considering various important factors for selection of the proper construction technology or methods on Mass rapid transit project in restricted area with obstructions in Thailand. This research aims to study those criteria that affect decision making of construction technology and their importance in terms of criteria weight for various types of Mass rapid transit project by interview and questionnaire. Three main criteria including Economic, Engineering and Social & Environment were analyzed by using the analytic hierarchy process (AHP), while the sub-criteria were identified by using Rank order centroid method (ROC), for various categories of structure. It is found that, for the Monorail project, Engineering is the most important criteria of 54% weight, Social & Environment and Economic are 2nd and 3rd criteria of 26% and 20%, respectively. The obtained relative weights of all main and sub-criteria were applied to the case study of the monorail Brown line project on Prasert-Manukitch road section which the alignment is overlapped with the new expressway project. The results show that the analyzed construction methods consistent with the project feasibility report. This can be implied that the relative criteria weights obtained from this study are reliable and applicable.
