In the context of climate change, problem water scarcity is becoming increasingly serious, and improving efficiency resources use an important measure to alleviate this problem. The evaluation utilization has become basis resource management. Data envelopment analysis (DEA) analytic hierarchy process (AHP) are widely used in efficiency. However, one these methods mostly for evaluation, which ca...

This paper applies Data Envelopment Analysis (DEA) and Elasticity Analysis to an empirical assessment study on innovation ability and innovation potentiality. According to inputs and outputs data of these innovative enterprises, we build CCR model, BCC model and Elasticity model to measure their innovation ability and innovation potentiality. The results show that innovation ability is varied b...

this paper uses integrated data envelopment analysis (dea) models to rank all extreme and non-extreme efficient decision making units (dmus) and then applies integrated dea ranking method as a criterion to modify genetic algorithm (ga) for finding pareto optimal solutions of a multi objective programming (mop) problem. the researchers have used ranking method as a shortcut way to modify ga to d...

Data Envelopment Analysis models are based on linear programming problems (LPP) to determine the efficiency of Decision-Making Units (DMUs). This process can be computationally intense, as a LPP has to be run for each unit. Besides, a typical DEA LPP has a large number of redundant constraints concerning the inefficient DMUs. That results in degenerate LPPs and in some cases multiple efficient ...

In many data envelopment analysis (DEA) applications, the analyst always confronts the difficulty that the selected data set is not suitable to apply traditional DEA models for their poor discrimination. This paper presents an approach using Shannon’s entropy to improve the discrimination of traditional DEA models. In this approach, DEA efficiencies are first calculated for all possible variabl...

This paper examines how well the public libraries in each state of USA combine their resources to support the largest amount of possible services to the community. It also investigates how to improve the performance of the inefficient libraries at state level. Data envelopment analysis (DEA) technique is employed for this research purpose. BCC model is utilized in order to consider the size eff...

This paper concentrates on methods for comparing activity units found relatively efficient by data envelopment analysis (DEA). The use of the basic DEA models does not provide direct information regarding the performance of such units. The paper provides a systematic framework of alternative ways for ranking DEA-efficient units. The framework contains criteria derived as by-products of the basi...

abstract there are varieties of researches for appraisal of results obtained by countries in olympics, using data envelopment analysis method. this research is aimed to make such appraisal for iranians’ results in olympics games using the dea method. before taking any measures, main issues of dea methods for appraisal of olympics games in the previous research were discussed, afterward optimiza...
