Evaluation of performance and productivity is among the fundamental concepts inmanagement. In order to achieve their goals, organizations must evaluate theirperformance. One of the important stages of performance appraisal is evaluation oforganization’s efficiency. Banks, financial and credit institutions are among the mostimportant organizations of every economic system, because every activity...

data envelopment analysis (dea) has been proven as an efficient technique to evaluate the performance of homogeneous decision making units (dmus) where multiple inputs and outputs exist. in the conventional applications of dea, the data are considered as specific numerical values with explicit designation of being an input or output. however, the observed values of the data are sometimes imprec...

an experiment was performed to investigate the energy efficiency and effect of poultry house size on energy productivity in 3 different capacity management systems. capacities of houses were 10000(3 housings), 20000 (2 housings) and 28000 (1 housing) birds per production period and were assigned as hi, hii and hiii respectively. this experiment was conducted in a completely randomized design ap...

We have developed a formal validation tool that has been used in several projects that are developing software for AT&T's 5ESS TM telephone switching system. The tool validates networks of communicating processes speciied in the Virtual Finite State Machine (VFSM) notation, which is used during the low-level-design phase of software development to specify the control behavior of an implementati...

The present study addresses the following question: if among a group of decision making units, the decision maker is required to increase inputs and outputs to a particular unit in which the DMU, with respect to other DMUs, maintains or improves its current efficiencylevel, how much should the inputs and outputs of the DMU increase? This question is considered as a problem of inverse data envel...

Examining the impacts of data modification is considered as sensitivity analysis. A lot of studies have considered the data modification of inputs and outputs in DEA. The issues which has not heretofore been considered in DEA sensitivity analysis is modification in the number of inputs and (or) outputs and determining the impacts of this modification in the status of efficiency of DMUs. This pa...

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. this paper suggests a new interval based approach to apply missing data, which is the modified version of kousmanen (2009) approach. first, the prop...
