皇室英语摘要：Summary: In an important class of multiobjective linear programming methods the determination of a satisfactory solution is realized by the maximization of the decision maker's utility function. Several methods have been propod for the asssment of utility functions. The methods require different types of information (cardinal or ordinal) and rely on different assumptions for the utility function, such as linearity, additivity and concavity. The latter property, although restrictive for the decision maker's preferences, provides a sufficient condition for a global optimum. In this paper an extension of the algor
ithm UTASTAR to the asssment of concave utility functions is prented. The new algorithm is illustrated by a numerical example. Finally, the degree to which the concavity restriction influences the results
