Method of Group Decision Making for Production Planning of the Oil Refinery Plant

Abstract

This article is devoted to the problem of decision making under uncertainty. An aggregated approach is used that combines optimization and choice of a solution, which makes it possible to obtain a more realistic solution. The criteria in the vector optimization problem are: profit, product quality, employee satisfaction. To solve the optimization problem, 3 methods were used: “Goal programming”, “Interactive”, “FMOLP”. The task of group decision making is implemented on the basis of the package FGDSS-CD (Fuzzy group Decision Support System).
