In this paper, we propose a new Most of the real-world decision problems occur in a method for risk assessment of a tunnel project where there complex environment where conflicting systems of logic, are three main parameters called taskmaster, adviser, and uncertain, and imprecise knowledge need to be considered. contractor. The proposed model of this paper is built based To face such complexity, preference modeling needs the use on interactive framework of a game theory where, in of specific tools, techniques, and concepts to reveal the making decision, each player considers other possible risks available information with the appropriate granularity [ 1, choices. We implement three-person cooperative game 2]. There are many cases such as choice of alignment or theory combined with an interactive decision structural selection of construction methods where the risk manage- model of fuzzy analytical hierarchy process to perform a ment becomes vital in the early stages of a project [3].
