Competitive market conditions today are becoming more challenging in every sector. Companies must determine their road maps in terms of short, mid and long-term strategies. The selection of the most suitable strategy by a group of decision makers is a very complicated process. As the same linguistic expression can represent different meanings to different people the fuzzy decision-making process is a good tool to use in group decisions. Various methods and different linguistic terms are used to define fuzzy sets. In recent years, the interval type-2 fuzzy AHP and interval type-2 TOPSIS methods have been introduced in the literature, as well as the type-1 fuzzy AHP and type-1 fuzzy TOPSIS methods. The aim of this study is to present a new model for group decision-making with the Balanced Score Card, fuzzy AHP and fuzzy TOPSIS methods by using interval type-2 fuzzy sets. The proposed model was applied in the strategy selection process of a large-scale public transportation company that operates in Istanbul/Turkey.
