選好記録からの多属性効用関数の同定に関する研究

抄録

A new method for the identification of multiattribute utility functions is proposed. By this method, multiattribute utility functions are estimated from the comparisons of alternatives. Through the comparisons, the orders of examined attributes and the preferences of decision-maker are recorded. First, this data are analized using the ranking method. And under a hypothesis that the utility function is additive, the derivation of the utility function is formulated as a linear programming problem.
We applied this method to the priority rating of urban roads. From the result of this casestudy, it is recognized that the proposed method has a practical use.
