1. Merging DMUs Based on of the idea Inverse DEA

Elaheh Zeinodin; Saeid Ghobadi

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

Abstract
  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

2. An input-oriented radial measure for returns to scale aggregation.

Reza Kazemi Matin; Roza Aziz; Mahdi Mirjaberi

Volume 10, Issue 1 , Spring 2018, , Pages 19-29

Abstract
  In production theory, it is necessary to be capable of predicting the production func- tion’s long-run behaviors. Hereof, returns to scale is a helpful concept. Returns to scale describes the reaction of a production function to the proportionally scaling all its input variables. In this regard, ...  Read More

3. Inputs and Outputs Estimation in Inverse DEA

Saeid Ghobadi

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

Abstract
  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

4. 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

Abstract
  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

5. Ranking of bank branches with undesirable and fuzzy data: A DEA-based approach

Sohrab Kordrostami; Alireza Amirteimoori; Monireh Jahani Sayyad Noveiri

Volume 8, Issue 2 , Autumn 2016, , Pages 71-77

Abstract
  Banks are one of the most important financial sectors in order to the economic development of each country. Certainly, efficiency scores and ranks of banks are significant and effective aspects towards future planning. Sometimes the performance of banks must be measured in the presence of undesirable ...  Read More

6. Ranking efficient DMUs using the infinity norm and virtual inefficient DMU in DEA

Shokrollah Ziari; Manaf Sharifzadeh

Volume 8, Issue 2 , Autumn 2016, , Pages 79-86

Abstract
  In many applications, ranking of decision making units (DMUs) is a problematic technical task procedure to decision makers in data envelopment analysis (DEA), especially when there are extremely efficient DMUs. In such cases, many DEA models may usually get the same efficiency score for different DMUs. ...  Read More

7. Ranking efficient DMUs using the variation coefficient of weights in DEA

Mojtaba Ziari; Shokrollah Ziari

Volume 8, Issue 1 , Spring 2016, , Pages 9-16

Abstract
  One of the difficulties of Data Envelopment Analysis(DEA) is the problem of de_ciency discrimination among efficient Decision Making Units(DMUs) and hence, yielding large number of DMUs as efficient ones. The main purpose of this paper is to overcome this inability. One of the methods for ranking efficient ...  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

Abstract
  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

9. Performance Evaluation of Banks Using DEA (Case study: Guilan Saderat Bank Branches)

K. Shahroudi; Sh. Assimi

Volume 4, Issue 2 , Summer 2012, , Pages 324-335

Abstract
  Performance evaluation has been developed in the form of management schools along by managerial thought development. Banks and financial institutes are one of the most important economic sections to each country which by receipts and payments directing and organizing facilitate business ...  Read More
