Using Fuzzy Matter-Element Model and Triangular Fuzzy AHP Method to Select the International Construction Project Material Suppliers

Abstract:

Selection of material supplier is important to international construction project management, and can bring impacts on the project's quality, schedule and cost. Considering the features of international construction projects, we built a selection decision-making evaluation index system. Triangular fuzzy AHP (Analysis of Hierarchy Process) method was used to calculate the weights of evaluation index. Using the medium value of triangular fuzzy number, a simple and convenient method was developed to test the consistency of judgment matrix. Base on calculating the weights of evaluation index, a fuzzy matter-element model was proposed to calculate the comprehensive evaluation values. Taking the selection of cement suppliers of the Congo (Brazzaville) National Road One Second Project as an example, the Euclid closeness of alternative suppliers was calculated to determine the ranking order of alternatives.
