Fuzzy measures, also known as capacities, nonadditive measures, and monotonic games, are increasingly usedin all kind of applications. Fuzzy measures are set functions. So, for a given set X, we need to define 2|X| − 2 parameters (excluding the measure on the empty set and on X itself). Becauseof that they are difficult to visualize, and indices and metrics havebeen defined. The Shapley value is an example. It permits us todetermine weights of importance of each element in X. In this paper we introduce an alternative index. We call it Υ-values. We provide an axiomatic characterization. These valuesare inspired on the Shapley values, and they are associated to setsize, or position (order statistics) in a chain. Thus, also positionwhen the measure is used in combination with a fuzzy integral. Andness and orness are measures that permit to evaluatethe degree of simultaneity (conjunction) and substitutability (disjunction) of an aggregation function. We show the connectionbetween our value and these concepts. In a way, Υ-values definea power index à la orness.
