Using the DEA-R model in the hospital industry to study the pseudo-inefficiency problem
TL;DR: This study puts forward the DEA-R-I as a capable substitutive model for CCR-I in order to avoid pseudo-inefficiency and proved that it is a valid model.

Exploration of efficiency underestimation of CCR model: Based on medical sectors with DEA-R model
TL;DR: When analyzing the medical sectors of Taiwan with the developed models and CCR, it is found that efficiency underestimation by efficient DMUs is more serious than that of inefficient DMUs.

A study of developing an input-oriented ratio-based comparative efficiency model
TL;DR: It is proved that the efficiency score of DEA-R-I is greater than that of CCR-I, which is the first and most popular model of DEA, in input-oriented situations without weight restrictions to claim the DEA- R-I can replace the CCR model in these situations.

Trends in Research about COVID-19 Vaccine Documented through Bibliometric and Visualization Analysis
TL;DR: In this paper , the authors used bibliometric analysis and visualization to document research trends regarding COVID-19 vaccines, and offer some directions and suggestions for future research, which showed that the overall research trend was upward.
A study of optimal weights of Data Envelopment Analysis - Development of a context-dependent DEA-R model
TL;DR: This study proposes a context-dependent DEA-R model to address shortcomings resulting from redundant restraints on the weights of an efficient decision making unit (DMU), and converts the optimal weight to analyze the influences of redundant restraint on weights.
