evaluation of corporate performance has been one of the main issues in managing decision making. nowadays, evaluation of the suppliers is a completely strategic process because organizations rarely change their suppliers. thesuppliers also do their best to remain stable in the loop of supply chain. hence, it is important to evaluate the suppliers and not something to be done once at a time. it ...

Skin cancers are the most frequent human malignancies among Caucasians and the incidence is rising alarmingly due likely at least in part to increased exposure to ultraviolet-light (UV) as a consequence of decreasing ozone levels and increase in outdoor recreational activities. Skin tumors include malignant melanomas and non-melanoma skin cancers (NMSC) that are neoplasms of epithelial origin s...

This paper presents the results of an efficiency study of Colombian public universities in 2012, conducted using the methodology of Data Envelopment Analysis (DEA) and the models CCR, BCC and SBM under output orientation. The main objective is to determine technical, pure technical, scale and mix efficiencies using data acquired from the Ministry of National Education. An analysis of the result...

The data envelopment analysis (DEA) model is extensively used to estimate efficiency, but no study has determined the DEA that delivers most precise estimates. To address this issue, we advance Monte Carlo simulation-based generation process proposed by Kohl and Brunner (2020). developed generates an artificial dataset using Translog production function (instead of commonly Cobb Douglas) constr...

ABSTRACT: Based on the goal of income increasing, this research uses DEA-BCC model under input and output orientation to estimate differences changes in technical efficiency wheat production by farmers different scales based survey data 1669 farmers’ from China’s main wheat-producing regions. Results showed that there are significant farmer’s optimal scale orientation. The relationship between ...

one of the most popular approaches to measuring productivity changes is based on using malmquist productivity indexes. in this paper we propose a method for obtaining interval malmquist productivity index (impi). the classical dea models have been before used for measuring the malmquist productivity index. the current article extends dea models for measuring the interval malmquist productivity ...

Recently, a mixed integer data envelopment analysis (DEA) model has been proposed to find the most BCC-efficient (or the best) decision making unit (DMU) by Toloo (2012). This paper shows that the model may be infeasible in some cases, and when the model is feasible, it may fail to identify the most efficient DMU, correctly. We develop an improved model to find the most BCC-efficient DMU that r...
