A novel decision-making method using fuzzy DEA credibility constrained and RC index

Ranking Decision Making Units in Fuzzy-DEA Using Entropy

Abstract Data Envelopment Analysis (DEA) can be regarded as a useful management tool to the assessment evaluation of decision making units (DMUs) using multiple inputs to produce multiple outputs. In some cases, to evaluate the efficiency having imprecise inputs and outputs such as fuzzy or interval data the efficiency of DMUs won’t be exact as well. Most researches have been conducted were bas...

A Fuzzy Decision Making Method in Developing Environmental Performance Index

Environmental Performance Index (EPI) is used to rank the performance in environment protection for most of the countries in the world. EPI is a score which gives a gauge at a national government scale using the method of proximity-to-target value. The current method fails to consider incomplete and vague environment data in its computations. This paper proposes a new score of EPI using a decis...

Ideal and anti-ideal decision making units: A fuzzy DEA approach

In this paper, by introducing two virtual decision-making units (DMUs) called ideal DMU (IDMU) and anti-ideal DMU (ADMU) with fuzzy inputs-outputs, the efficiency evaluation of DMUs are done by fuzzy data envelopment analysis (FDEA). Therefore, we evaluate DMUs from the perspective of the best and worst possible relative efficiency. For each DMU two efficiencies are calculated while inputs and ...
