Managerial decisions should be made by taking into account the priorities and objectives of different stakeholders' groups. Their preferences are usually expressed in words and are fuzzy concepts. This article analyses the peculiarities of companies' work and decision-making within a fuzzy market situation. It also presents a developed fuzzy multi-criteria group decision-making model for practical problem solving by taking into account cost-effective management. This case study presents a selection of rational criteria set to use in the weighted cost-effectiveness analysis for facilities management strategies, in which integrated fuzzy multi-criteria decision-making methods are applied. The main findings are: the model is adopted to real-life; the main criteria groups are identified by a three-step Delphi technique; a rational strategy is determined and integrated in one model by the concept of Minkowski distance and fuzzy TOPSIS method, ARAS-F and fuzzy weighted product method. The proposed model is versatile and therefore can be applied for various problems were the experts' knowledge needed for decision-making. (C) 2017 Elsevier Ltd. All rights reserved.
