1. Efficiency Evaluation in Presence of Undesirable and Negative Factors

Mahnaz Maghboulı; Mahdi Eini; farhad taher

Volume 12, Issue 2 , Autumn 2020

  Data envelopment analysis (DEA) has been proven as an excellent data-oriented efficiency analysis method for comparing decision making units (DMUs) with multiple inputs and multiple outputs. In conventional DEA models, it is assumed that the input or output variables are all non-negative and desirable. ...  Read More

2. Merging DMUs Based on of the idea Inverse DEA

Elaheh Zeinodin; Saeid Ghobadi

Volume 11, Issue 2 , Autumn 2019, , Pages 77-84

  In this paper, we propose a novel method using multiple-objective programming problems to answer the following question: if among a group of decision making units (DMUs), a subset of DMUs are required to merge and form a new DMU with specific input/output levels and a predefined efficiency target, how ...  Read More

3. A Hybrid model based on neural network and Data Envelopment Analysis model for Evaluation of unit Performance

Sadegh Heidary; Ehsan Zanburi; Hhamid Parvin

Volume 10, Issue 2 , Autumn 2018, , Pages 101-112

  Efficiency and evaluation is one of the main and most important demands of organizations, companies and institutions. As these organizations deal with a large amount of data, therefore, it is necessary to evaluate them on the basis of scientific methods to improve their efficiency. Data envelopment analysis ...  Read More

5. Inputs and Outputs Estimation in Inverse DEA

Saeid Ghobadi

Volume 9, Issue 2 , Autumn 2017, , Pages 119-129

  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 ...  Read More

6. An approach to rank efficient DMUs in DEA based on combining Manhattan and infinity norms

Shokrollah Ziari; Manaf Sharifzadeh

Volume 9, Issue 1 , Spring 2017, , Pages 13-19

  In many applications, discrimination among decision making units (DMUs) is a problematic technical task procedure to decision makers in data envelopment analysis (DEA). The DEA models unable to discriminate between extremely efficient DMUs. Hence, there is a growing interest in improving discrimination ...  Read More

7. Alternative ranking method in Dynamic Data Envelopment Analysis (DDEA)

Mahnaz Maghbouli; Omid Yaghbubi agreh; Zahra Mohammadnezhad

Volume 7, Issue 2 , Autumn 2015, , Pages 839-848

  The motivation of this paper is to propose such equitable method for ranking all decision making units (DMUs) in dynamic Data Envelopment Analysis (DDEA) framework. As far as we are aware there is not more studies in dynamic DEA literature. What's more, in such cases the best operating unit is important ...  Read More

8. A statistical test for outlier identification in data envelopment analysis

Morteza Khodabin; Reza Kazemi Matin

Volume 6, Issue 1 , Winter 2014, , Pages 678-690

  In the use of peer group data to assess individual, typical or best practice performance, the effective detection of outliers is critical for achieving useful results. In these ‘‘deterministic’’ frontier models, statistical theory is now mostly available. This paper deals with ...  Read More
