Adding weight restrictions on multiplier DEA models to incorporate value judgments is equivalent to accepting trade-offs between inputs and outputs in envelopment forms. To obtain the corresponding DEA model with the trade-off axiom, the production p

The concept of Returns to scale is an important topic in data envelopment analysis since it identifies whether the expansion or contraction of the unit under assessment is beneficial. The quantity of the beneficial expansion or contraction is determi

One problem that has been discussed frequently in data envelopment analysis (DEA) literature has been lack of discrimination in DEA applications, in particular when there are insufficient DMUs or the number of inputs and outputs is too high relative

Data envelopment analysis (DEA), which is used to determine the efficiency of a decision-making unit (DMU), is able to recognize the amount of input congestion. Moreover, the relative importance of inputs and outputs can be incorporated into DEA mode

The two-level DEA model was introduced to increase the discriminational power of Data Envelopment Analysis (DEA) models. This nonlinear model was presented by Meng et al. (2008) [3] , and then converted into a linear model by Kao (2008) [4] . In this

Data Envelopment Analysis is used to determine the relative efficiency of Decision Making Units as the ratio of weighted sum of outputs by weighted sum of inputs. To accomplish the purpose, a DEA model calculates the weights of inputs and outputs of

Some methods have been presented for ranking efficient decision making units (DMUs) in data envelopment analysis (DEA). This paper addresses the ranking of interval data by using Monte Carlo method. This method is based on a paper [G.R. Jahanshahloo,

Production Possibility Set (PPS) is defined as the set of all inputs and outputs of a system in which inputs can produce outputs. Data Envelopment Analysis models implicitly use PPS to evaluate relative efficiency of Decision Making Units (DMUs). Alt

The paper considers the problem ranking interval data in data envelopment analysis (IDEA), different of the other methods. In this approach, we use the statistical concepts. The end DEA models are modified and for illustration a numerical example is
