Data Envelopment Analysis
1. 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

2. Obtaining a Unique Solution for the Cross Efficiency by Using the Lexicographic method

G. R. Jahanshahloo; R. Fallahnejad

Volume 6, Issue 1 , Winter 2014, Pages 691-701

Abstract
  Cross efficiency is a method with the idea of peer evaluation instead of self-evaluation, and is used for evaluation and ranking Decision Making Units (DMUs) in Data Envelopment Analysis (DEA). Unlike most existing DEA ranking models which can only rank a subset of DMUs, for example non-efficient or ...  Read More

3. Linear Programming, the Simplex Algorithm and Simple Polytopes

Das Sashi Bhusan; Biswal Bagaban; J.P Tripathy

Volume 6, Issue 1 , Winter 2014, Pages 702-719

Abstract
  In the first part of the paper we survey some far reaching applications of the basis facts of linear programming to the combinatorial theory of simple polytopes. In the second part we discuss some recent developments concurring the simplex algorithm. We describe sub-exponential randomized pivot roles ...  Read More

4. A new method for ordering triangular fuzzy numbers

S.H. Nasseri; S. Mizuno

Volume 6, Issue 1 , Winter 2014, Pages 720-729

Abstract
  Ranking fuzzy numbers plays a very important role in linguistic decision making and other fuzzy application systems. In spite of many ranking methods, no one can rank fuzzy numbers with human intuition consistently in all cases. Shortcoming are found in some of the convenient methods for ranking triangular ...  Read More
