[ 1 ] - Two-stage network DEA-R based on value efficiency
It is essential for most organizations and financial institutes to be able to evaluate their decision-making units (DMUs), when there is only a ratio of inputs to outputs (or vice versa) available. In this paper, we will propose our two-stage DEA-R models, which are a combination of data envelopment analysis and ratio data, based on value efficiency. Integrating value efficiency into data envel...
[ 2 ] - تخصیص منابع مرکزی براساس کارایی ارزش در DEA و DEA-R
In this article, centralized resource allocation (CRA) models based on the value efficiency in DEA and DEA-R are recommended. In general, if the input and output data of decision-making units are available, DEA models provide targets of units on the efficiency frontier in addition to the efficiency of units. However, if only a ratio of the input data to output data, or vice versa, is available,...
[ 3 ] - Finding Common Weights in Two-Stage Network DEA
In data envelopment analysis (DEA), mul-tiplier and envelopment CCR models eval-uate the decision-making units (DMUs) under optimal conditions. Therefore, the best prices are allocated to the inputs and outputs. Thus, if a given DMU was not efficient under optimal conditions, it would not be considered efficient by any other models. In the current study, using common weights in DEA, a number of...
[ 4 ] - Cost efficiency in three stage network DEA-R processes
In many organizations and financial institutions, we don't always have acsses to inputs and outputs to evaluate the decision-making units (DMUs), but rather only a ratio of inputs to outputs ( or reverse) might be available. In DEA, cost efficiency determines input standards based on input costs. In multi-stage network DEA processes, in addition to input standards, cost efficiency would determi...
