【Abstract】 This paper studies a kind of uncertain multi-attribute decision-making problems,in which the partial information about the attribute weights is known and the attribute values are in the forms of triangular fuzzy numbers.In this paper,we give the concrete formula of Hausdauff distance of the triangular fuzzy numbers.The deviation degrees bwtween triangular fuzzy attribute values are measured by applying Hausdauff distance,a linear programming model is established for obtaining the attribute weights,and the priority based on possibility degree for the uncertain multi-attribute decision-making problem is proposed.Finally,an illustration is given to show the feasibility and effectiveness of the method.更多还原
