Multiple Criteria Decision Making methods have become very popular in recent years and are frequently applied in many real-life situations. The increasing complexity of the decision problems analysed makes it less feasible to consider all the relevant aspects of the problems by a single decision maker. As a result, many real-life problems are discussed by a group of decision makers. The aim of the paper is to present a new approach for ranking of alternatives with fuzzy data for group decision making using the TOPSIS method. In the proposed approach, all individual decision information of decision makers is taken into account in determining the ranking of alternatives and selecting the best one. The key stage of this method is the transformation of the decision matrices provided by the decision makers into matrices of alternatives. A matrix corresponding to an alternative is composed of its assessments with respect to all criteria, performed by all the decision makers. A numerical example illustrates the proposed approach.
