【Abstract】 This paper studies a kind of uncertain multi-attribute decision-making problems,in which the information about the (attribute) weights unknown are completely and the attribute values are in the forms of triangular fuzzy numbers.The deviation degrees between the triangular fuzzy attribute values are measured by applying dispersion coefficient of fuzzy-valued data,a simple formula for obtaining the attribute weights is given,and a priority method based on possibility degree for the uncertain multi-attribute decision-making problem is also proposed.更多还原
