Selection of Prefabricated Concrete Factories' Location Based on Triangular Fuzzy Numbers and Fuzzy Group Decision-Making

Abstract

In China, owing to some promotion policies of prefabricated buildings, the enterprises of precast concrete components grow by leaps and bounds. However, there are lots of influence factors of selecting PC factories' locations. It's a complex and multi-criteria decision-making problems. How to make a right decision is very important because the location will affect the operation cost and core competence. The paper puts forward four primary criterion: the geographical factors, economic factors, social and environmental factors on the basis of summarizing the related research results, combining with the experience of the experts and the characteristics of the precast concrete components techniques. There are total 19 secondary criteria under the primary ones. Then the paper presents a fuzzy group decision-making model based on the triangular fuzzy numbers. Finally an example is given to prove the model's validity and scientificity. The research result will provide a new method and idea to select the precast concrete factories' locations.
