TL;DR: Wang et al. as mentioned in this paper presented an equitable model for efficiency evaluation of decision-making units with undesirable outputs and introduced a technique for cross-efficiency evaluation considering undesirable outputs, and a ranking priority model was proposed considering the decision making units' intentions of pursuing the best ranking positions.

TL;DR: A new DEA model is proposed to evaluate the environmental efficiency of a two-stage system with undesired outputs and three theorems are established to show the relationships between the interest preference parameter and the change of efficiency scores.

TL;DR: A DEA-based bi-objective model is put forward to evaluate the hotel performance from the perspective that the two internal stages cooperate with each other, and offers a comprehensive benchmarking tool to improve hotel decision-making.

TL;DR: In this paper, a new DEA cross-efficiency evaluation approach, which contains a maxmin model and two algorithms, is proposed based on the satisfaction degrees of the decision-making units (DMUs).

TL;DR: Improved data envelopment analysis (DEA) models are utilized to evaluate the regional total-factor energy and environmental efficiency of China during the 11th 5-year plan period (2006–2010), showing that most of mainland China’s provincial-level regions have low energy andEnvironmental efficiency.
