The extent to which the structural reform of Peruvian electricity market in 1990s has improved technical efficiency levels distribution companies and whether some firm specific explanatory variables had influenced upon was analysed for first time using a second stage Tobit model study influence on efficiency. Some authors have argued that use regression is inappropriate DEA suggested other rece...

Network data envelopment analysis (NDEA) is an extension of standard DEA that models the efficiency assessment decision-making units (DMUs) by considering their internal structure. While in DEA, DMU regarded as a single process, NDEA, viewed network interconnected sub-processes (stages, divisions), where flow intermediate products (measures) essential assessment. In prevalent conventional metho...

the ahp/dea methodology is an integration of analytical hierarchical process (ahp) and data envelopment analysis. this method uses the capabilities of both ahp and dea. however, it has some problems: it illogically compares two decision-making units in a data envelopment analysis (dea) model, it is not compatible with dea ranking in the case of multiple inputs/multiple outputs, and it leads to ...

data envelopment analysis (dea) is a method for measuring the efficiency of peer decision making units (dmus) which uses a set of inputs to produce a set of outputs. in some cases, dmus have a two-stage structure, in which the first stage utilizes inputs to produce outputs used as the inputs of the second stage to produce final outputs. one important issue in two-stage dea is the sensitivity of...

this study uses the data envelopment analysis (dea) to assess the progress/regression of decision-making units (dmus) having a two-stage structure‎. ‎the progress/regression of these dmu can be assessed in the first stage‎, ‎the second stage‎, ‎and the whole system‎. ‎in the first stage‎, ‎the progress/regression of bank branches in collecting resources and in the second stage their progress/re...

Data envelopment analysis (DEA) is a method used for measuring the efficiency of decision-making units‎. Unlike the standard models‎, ‎which assume decision-making units to be a black box‎, ‎network data envelopment analysis focuses on the internal structure of these units‎. ‎Some researchers have developed a two-stage method where all the inputs are entirely used in the first stage‎, ‎producin...
