Condorcet voting theory based on analytical hierarchy process (AHP) for project selection problems

Abstract

Project selection is a process of evaluating a set of proposals and hence selecting the most potential project to be completed. This process is a challenging task for decision makers since the process involves many conflicting criteria and due to the limited resources, not all the projects can be implemented. Therefore, Condorcet Voting Theory based on Analytical Hierarchy Process (AHP) method is used to solve the project selection problems. The Condorcet Voting Theory based on AHP is a method to solve the multi-criteria decision making (MCDM) problems where the voters will cast their votes to choose between two candidates. The quantitative ratio of the votes given to the candidates will be further used to construct the pairwise comparison matrix instead of the 9-points Saaty scale in the traditional AHP approach. The objectives of this study are to solve the project selection problems using Condorcet Voting Theory based on AHP method and to do comparison between AHP method and Condorcet Voting Theory based on AHP method. A real-life empirical data on the factors that contribute to road accidents was used to demonstrate the application of Condorcet Voting Theory based on AHP method. Decision makers will be able to make a judgment in a simple way by using voting method as the decision makers or the voters will cast their votes to select or not to select the alternatives.
