Decision making under fuzzy constraints and fuzzy criteria – mathematical programming vs. rule-based system approach. (English) Zbl 0826.90125
Delgado, Miguel (ed.) et al., Fuzzy optimization. Recent advances. Heidelberg: Physica-Verlag. Stud. Fuzziness. 2, 21-32 (1994).
Summary: This short paper tries to clarify some basic issues on optimization in a fuzzy environment. After a general discussion of what fuzzy optimization means, this note analyzes and compares three approaches to the selection of a good candidate according to a multiple criteria evaluation, namely i) mathematical optimizaton of a function aggregating criteria and constraints; ii) use of a fuzzy rule-based description of the choice procedure; iii) choice made on the basis of exemplifications of what is a good decision and a less good one.
