AB Data envelopment analysis (DEA) models play a significant role in evaluating the efficiencyof decision-making units (DMUs) among multiple input and output variables in many fields,such as industry or economy. This method establishes a production possibility set (PPS) thatdefines the efficient ones, the efficiency boundary or frontier, and provides the projectioninto the latter, or targets, for the inefficient ones. This paper introduces an enhanced hybridinterval slacks-based DEA when information on inputs and outputs can be discrete (integer)or continuous (real) and presents uncertainty, which can be modeled using intervals (integeror continuous). To this matter, we propose a novel approach that calculates crisp inefficiencyscores, interval slacks, and interval targets using interval arithmetic and LU-partial orderson intervals. Mainly, the novelty is based on a reduction and simplicity of the model withrespect to others existing, as well as the inclusion of integer interval-valued information withthe corresponding mathematical tools and previous results. A super-efficiency slacks-basedmodel is also provided to distinguish among the efficient DMUs and provide a full rank forthe set of DMUs. We finally present the practical application of our method in tourism, anessential economic sector in Spain, focusing on different coastal areas.
