Conventional data envelopment analysis (DEA) models are used to measure efficiency score of production systems when they are considered as black boxes and their internal relationship is ignored. This paper deals with a common special case of network

Traditional data envelopment analysis (DEA) models deal with measurement of relative efficiency of decision making units (DMUs) in which multiple-inputs consumed to produce multiple-outputs. One of the drawbacks of these models is neglecting internal

In the classical data envelopment analysis (DEA) models, inputs and outputs are assumed as known variables, and these models cannot deal with unknown amounts of variables directly. In recent years, there are few researches on handling missing data. T

Data envelopment analysis (DEA) is a non-parametric approach for performance analysis of decision making units (DMUs) which uses a set of inputs to produce a set of outputs without the need to consider internal operations of each unit. In recent year

Recently in the insurance sector, efficiency measurement of insurance firms has attracted great interest from investors, financial market analysts, insurance regulators, and researchers alike. Among several performance assessment approaches, Data Env

The objective of this paper is to develop new models to compare cost efficiency of decision making units (DMUs) in all feasible input/output weights. Our focus is to determine cost ranking intervals and cost dominance relations in which the former sh

Traditional DEA methods treat a production unit as a black box without any consideration to the internal relations of its sub-processes. In recent DEA literature, there are many researches about production systems with network structure, in which out

Conventional DEA models have been introduced to deal with non-negative data. In the real world, in some occasions, we have outputs and/or inputs, which can take negative data. In DEA literature some approaches have been presented for evaluating perfo

In this paper, we propose a new approach to rank two-stage production systems in data envelopment analysis based on performance of the stages. To do this, a method is devised to compare the stages performance of a special two-stage unit with the corr

Evaluating profit efficiency measure needs input costs and output prices as well as input–output quantities. It is important to rank production units based on relative or absolute values of their production when costs and prices are available. Rank
