This article presents a new DEA (data envelopment analysis) approach, referred to as 'DCR (DEA cross-reference) efficiency measure'. This DCR approach is extended into a new sensitivity analysis technique referred to as 'DCS (DEA cross-sensitivity)', that examines the stability of DEA efficiency...

A new use of the nonparametric statistic, referred to as the "Kruskal and Wallis rank test", is proposed in this study. The nonparametric statistic examines whether or not any frontier shift occurs among observed periods. To document its practicality, the proposed statistic is incorporated into...

DEA (Data Envelopment Analysis) is a management science method that has been widely applied for performance analysis in various sectors. A shortcoming of previous DEA applications is that it has been used to mainly evaluate ex ante performance. Believing that future planning is more important...

This article describes a new DEA (data envelopment analysis) ranking approach that combines efficiency analysis (by DEA) with index measurement (by DEA sensitivity analysis). The sensitivity analysis, incorporated into the index measurement, omits an efficient DMU (decision making unit) to...
