A Camel Research Station was established in 1990 at the central desert land of Iran named Kavir-e-loot, to evaluate productivity performance of one humped camel. The data consisted of birth weights (BW), three (W3), six (W6), nine (W9) months and yearling (W12) body weight of animals and the pedigree was registered during a period of 14 years since 1991 to 2004. The body weight traits of birth,...

The conventional paradigm in data envelopment analysis (DEA) is to develop an efficiency measurement model that assumes the input and output data are precise and equal to some nominal values. However, this paradigm does not take into consideration the inherent uncertainties in real-life performance measurement problems. As a result of these uncertainties, the input and output data may take non-...

In this paper a ranking method using common weights methodology is presented. The goal of the enhancing decision maker (DM)’s influence in procedure. Although DM’s preference information an important element our method, approach can also be modified to used absence it. Since we aim implement on empirical instance, model deal with properties sample, so it developed presence interval data and fle...

Data envelopment analysis (DEA) has been recently employed for performance and efficiency evaluation of decision-making units (DMUs) with multiple inputs outputs. Complex internal relations within a DMU required more accurate DEA models than existing classic DEA. In real world applications, shared resources, among stages supply chain, is great interest managers decision makers. Unfair allotment...

A separation method to be used for locating a set of weights, also known as a common set of weights (CSW), in the Data Envelopment Analysis (DEA) is proposed in this work. To analyze the methods of finding the CSW, it is necessary to solve a particular form of a multiple objectives fractional linear programming problem (MOFP). One of the characteristics of this particular MOFP is that the decis...

DEA Classic models cannot be used for inaccurate and indeterminate data, and it is supposed that the data for all inputs and outputs are accurate and determinate. However, in real life situations uncertainty is more common. This article attempts to get the common weights for Decision-Making Units by developing DEA multi-objective models in the grey environment. First, we compute the privilege o...

This paper deals with the selection of the profiles of weights to be used in cross-efficiency evaluations. In an attempt to prevent unrealistic weighting schemes, one of the issues of main interest that we address here is that of the zero weights, since their use implies that some of the variables considered are excluded from the assessments to be made. In the calculation of cross-efficiency sc...

This paper considers single-machine position-dependent weights scheduling problem with past-sequence-dependent delivery times and truncated sum-of-processing-times-based learning effect. The objective is to minimize the weighted sum of due date, number early jobs tardy jobs, where are weights. Under common slack date different assignments, optimal properties given, corresponding solution algori...

Certain problems in coding theory translate naturally into problems concerning point sets in projective or affine space with special intersection properties with respect to certain subspaces. As an example, consider a set of p points in AG(3, p) which intersects every plane in 0 mod p points. Must this set necessarily be the union of p parallel lines? In the talk a very much related problem wil...
