Industrial Multiple Criteria Decision Making Problems Handled by Means of Fuzzy Inference-Based Decision Support Systems

Multiple Criteria Decision Making (MCDM) was introduced in the early 70s to solve decisions and planning problems involving multiple independent criteria. In many real applications the decision making problems are vague and uncertain, also a fuzzy multi-criteria decision making (FMCDM) approach for selecting the best strategies is preferable. This paper proposes two different fuzzy multi-criteria decision making approaches for selecting the best strategies to put into practice in two real world problems coming from a steel making industry.
