In this paper, we present the induced uncertain Euclidean ordered weighted averaging distance (IUEOWAD) operator. It is an extension of the OWA operator that uses the main characteristics of the induced OWA (IOWA), the Euclidean distance and uncertain information represented by interval numbers. The main advantage of this operator is that it is able to consider complex attitudinal characters of the decision-maker by using order-inducing variables in the aggregation of the Euclidean distance. Moreover, it is able to deal with uncertain environments where the information is very imprecise and can be assessed with interval numbers. We study some of its main properties and particular cases such as the uncertain maximum distance, the uncertain minimum distance, the uncertain normalized Euclidean distance (UNED), the uncertain weighted Euclidean distance (UWED) and the uncertain Euclidean ordered weighted averaging distance (UEOWAD) operator. We also apply this aggregation operator to a group decision-making problem regarding the selection new artillery weapons under uncertainty.A wide range of aggregation operators are found in the literature (Beliakov et al. 2007;Calvo et al. 2002;Torra, Narukawa 2007;Yager et al. 2011). One common aggregation method is the ordered weighted averaging (OWA) operator (Yager 1988). It provides a parameterized family of aggregation operators that include as special cases the maximum, the minimum and the average. Since its appearance, the OWA operator has been used in a wide range of applications (Chang, Wen An interesting extension of the OWA operator is the induced OWA (IOWA) operator (Yager, Filev 1999). The difference is that the reordering step is no longer determined only by the values of the arguments, but could be induced by another mechanism, such as the ordered position of the arguments; in other words, the reordering can depend on the values of their associated order-inducing variables. In the last few years, the IOWA operator has received increasing attention, e.g. to use another approach that is able to assess the uncertainty such as the use of interval numbers (Moore 1966; Xu, Da 2002). By using interval numbers we can consider a wide range of possible results between the maximum and the minimum. In order to extend the IOWA operator to accommodate these uncertain situations, Xu (2006) developed the uncertain IOWA (UIOWA) operator. Basically, it is an aggregation operator that deals with uncertain information represented in the form of interval numbers. Since its introduction, several authors have developed further improvements. For example, Merigó and Casanovas (2011d) generalized it by using generalized and quasi-arithmetic means and developed the uncertain induced quasi-arithmetic OWA (Quasi-UIOWA) operator. Based on the heavy OWA (HOWA) operator, Merigó and Casanovas (2011e) developed the uncertain induced heavy OWA (UIHOWA) operator. Merigó et al. (2012) developed the uncertain induced ordered weighted averaging-weighted averaging (UIOWAWA) operator.A further interesting...
