Multicriteria decision making using fuzzy logic

A new method for solving multicriteria decision problems is represented. In a manner similar to the analytic hierarchy process or the utility value analysis the goals and subgoals are ordered in a hierarchical structure. The goals on the lowest level are valuated by means of linguistic variables based on cardinal or ordinal scales which are proposed by experts. The evaluations of the subgoals are aggregated by using expert rules and fuzzy inference.
