AB This paper introduces an axiomatic approach to integer fuzzy DEA for efficiency assessment.To this end, we model the information by means of a new class of trapezoidal integer fuzzynumbers, also considering a hybrid scenario.Using integer fuzzy arithmetic and partial orders,we propose a non-oriented slacks-based integer fuzzy DEA approach that allows computinginefficiency scores as well as efficient fuzzy targets. The proposed approach involves twophases, with the phase II model required to distinguish between efficient, weakly efficient,and inefficient units. Several numerical examples are provided to illustrate and explain thenew concepts and the proposed approach.
