Efficiency and Effectiveness with interval indices in stochastic environments

چکیده مقاله:
Non-parametric DEA is a technique on the basic of mathematical programming to determine the efficiency of homological decision making units. DEA models changes in demand cause changes in variations in output levels and also will cause changes in a firm’s inefficiency. Often a firm can adjust input influencing on the output level. Models designed with technique on DEA that considers changes in demand and with a short-run capacity planning method quantifies the effectiveness of a firm’s production system under demand uncertainty. The DEA is assumed that accurate data input, output and demand. In some cases data observed with a difference or mistake, so the uncertainties involved in achieving predetermined goals. To measure the effectiveness of the techniques DEA data is important in the evaluation of uncertainty. Data input, output and demand can be interval and probable and order, ect. This paper focuse uncertain data that it is interval and models will be propone for calculation effectiveness and the effect of uncertain demand with interval data.

Efficiency Evaluation and Ranking DMUs in the Presence of Interval Data with Stochastic Bounds
On account of the existence of uncertainty, DEA occasionally faces the situation of imprecise data, especially when a set of DMUs include missing data, ordinal data, interval data, stochastic data, or fuzzy data. Therefore, how to evaluate the efficiency of a set of DMUs in interval environments is a problem worth studying. In this paper, we discussed the new method for evaluation and ranking i...
متن کاملNonparametric Efficiency EstimationIn Stochastic Environments
This paper develops a new nonparametric model for efficiency estimation. In contrast to Data Envelopment Analysis (DEA), it does not impose debatable production assumptions like free disposability and convexity, and it does not assume that the data are measured without error. The estimators are asymptotically unbiased and have an asymptotic variance that is comparable to that of stochastic fron...

Decision making plays an important role in economics, psychology, philosophy, mathematics, statistics and many other fields. In each field, decision making consists of identifying the values, uncertainties and other issues that define the decision. In any field, the nature of the decisions is affected by environmental characteristics. In this paper, we are considered the production planning pro...

EFFICIENCY MEASUREMENT OF NDEA WITH INTERVAL DATA
Data envelopment analysis (DEA) is a non-parametric technique for evaluation of relative efficiency of decision making units described by multiple inputs and outputs. It is based on solving linear programming problems. Since 1978 when basic DEA model was introduced many its modifications were formulated. Among them are two or multi-stage models with serial or parallel structure often called net...
