Pluralism in Management Multiple Criteria Decision Making Methods

Decision-making is one of the main manager’s functions. Since different decision making approaches were emerged. Each of Philosophers, managers, sociologist and psychologists has different view to decision making. This research aim to have a new look at multiple criteria decision-making techniques by Pluralism theory. To achieve this goal we try to operationalize and redefine pluralism concept in the field of multiple criteria decision making. In this regard, Triangulation, Stability (sensitivity) analysis, Validity and Reliability as a quad dimension of pluralism is discussed. So the main innovation of present paper is extension of data pluralism beside of another three pillars of pluralism. Results of data pluralism reveal that there are significant relationship among Fuzzy, Crisp and grey approaches. Since the result of research is based of analyzing limited case, in Generalization of result, we must be cautious. Generalizability describes the extent to which research findings can be applied to settings other than that in which they were originally tested.Keywords: Quantative Decision Making, Pluralism, Triangulation, Reliability, Validity, Data Pluralism, Stability (Sensitivity).
