Approaches for discrete alternative multiple criteria problems for different types of criteria

In this paper we address two classes of discrete alternative multiple criteria decision making problems: problems in which ordinal and cardinal criteria are simultaneously involved and problems in which only cardinal criteria are involved. We suggest variations of our previously developed ordinal criteria approach [5] and we test the approaches on randomly generated problems. Our evaluation criteria are: the capability of the approach to find a highly preferred alternative and the amount of information required of a decision maker.
