AB This study proposes a non-radial slacks-based Inverse Data Envelopment Analysis (Inverse DEA)framework for decision-making units under interval data. To address uncertainty in both inputsand outputs, the methodology integrates interval arithmetic with partial ordering, enabling robustefficiency evaluation. The research investigates how output levels should be adjusted when inputsincrease, and the inefficiency score of a unit decreases by a specified proportion. An enhancedinverse DEA model is developed, and necessary and sufficient conditions for output estimationare derived through the Pareto optimal solutions of a multi-objective nonlinear program. Twoillustrative examples are provided to illustrate the applicability of the proposed approach underinterval data scenarios.
