Decision-making in the fuzzy environment on the basis of various compromise schemes

This paper proposes a method of formalization and solution to a problem of mode parameters selection in CTS on the basis of mathematical modelling. Decision-making problems on a selection of effective operation modes are formalized using the example of technological complex on benzene production. Since the studied object is characterized by multicriteriality and fuzziness, initial problems are formalized as multi-criteria problems of fuzzy mathematical programming and a heuristic algorithm of their solution is developed on the basis of methods of fuzzy mathematics. Formulations of decision-making problems and an algorithm of their solution are obtained by modifying various principles of optimality based on the methods of the fuzzy set theory.
