چکیده
the non-differentiability and implicit definition of boundary of production possibility set (pps) in data envelopment analysis (dea) are two important difficulties for obtaining directional characteristics, including different elasticity measures and marginal rates of substitution. also, imposing weight restrictions in dea models have some shortcomings and misunderstandings. in this paper we utilize the core concept of directional derivative theorem to calculate different elasticity measures in dea models with weight restrictions. some theorems have been proved in order to overcome the problem.

متن کاملComputation of efficient targets in DEA models with production trade-offs and weight restrictions
Some data envelopment analysis models have been introduced in the literature that incorporate production trade-offs between inputs and outputs or, equivalently, weight restrictions imposed on their dual models. Podinovski has given a procedure, consisting of three stages, for practical application of such models (Podinovski, 2007). In this paper, we present a counterexample to the first stage o...
متن کاملCongestion analysis in DEA inputs under weight restrictions
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 models by weight restrictions. These restrictions or a priori weights are introduced by the decision maker and lead to changes in models and efficiency...
متن کاملComputation of Congestion in DEA Models with Productions Trade-offs and Weight Restrictions
Our aim in this work is to determine congestion with productions trade-offs or, equivalently, under weights restrictions in data envelopment analysis (DEA). For this purpose, we review a two-model approach to evaluate congestion (Cooper et al, 1996), and after that we have brief view in relation with computation of efficient targets with production trade-off in Podinovski’s procedure (Podinovsk...
متن کاملParametric Dea Models with Weights Restrictions
In this article, we discuss a method for distributing a new input or output to a set of decision making units so that by the end of the distribution all units are considered efficient in the DEA-CCR concept. The formulation follows the pattern referred in the literature as parametric DEA. This paper’s contribution is introducing the possibility of modeling with the inclusion of constraints on t...
متن کاملScale Efficiency in DEA and DEA-R with Weight Restriction
In data envelopment analyze (DEA) the scale efficiency in the input-oriented CCR model is less than or equal to the scale efficiency in DEA based on the fractional analysis (DEA-R). Also, the scale efficiency in case of multiple inputs and one output and vice versa the scale efficiencies are equal in DEA and DEA-R. In this paper, first, DEA-R model with weight restrictions when there is relativ...
