【Abstract】 This paper studies a kind of uncertain multi attribute decision making problems,in which the information about the attribute weights is unknown completely and the attribute values are in the forms of interval numbers.Some formulas for normalizing the decision matrix with interval numbers are given.Furthermore,a simple formula of maximizing deviations,based on deviation degree,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.Finally,a numerical example is given to show the feasibility and effectiveness of the method.更多还原
