Background and aims: Assessment of performance indicator is one of the most important issues in the managerial systems that should be done in a correct way. The accuracy of the assessment is influenced by the assessors' judgment. This study was done in order to determine pattern of assessing of HSE unit performance in the steel industries. Methods: In this study, 7 experts were defined indic...
Data Envelopment Analysis (DEA) as a non-parametric method for efficiency measurement allows decision making units (DMUs) to select the most advantageous weight factors in order to maximize their efficiency scores. In most practical applications of DEA presented in the literature, the presented models assume that all inputs are fully desirable. However, in many real situations undesirable inpu...
A parallel distributed processing model of visual word recognition and pronunciation is described. The model consists of sets of orthographic and phonological units and an interlevel of hidden units. Weights on connections between units were modified during a training phase using the back-propagation learning algorithm. The model simulates many aspects of human performance, including (a) differ...
The major difficulty in evaluating individual player performance in basketball is adjusting for interaction effects by teammates. With the advent of play-by-play data, the plus-minus statistic was created to address this issue [5]. While variations on this statistic (ex: adjusted plusminus [11]) do correct for some existing confounders, they struggle to gauge two aspects: the importance of a pl...
a linear goal programming model for calculating common weights in data envelopment analysis problems
data envelopment analysis (dea) is a wide range of mathematical models that used for measuring the relative efficiency of a set of harmonic units whit similar inputs and outputs. this model calculates some different weight for input and output variables in each decision making model. this variation in similar weights caused some critiques to this method. from 1991 some linear and nonlinear mode...
This paper addresses talking head synthesis based on the concatenation of units comprising of both acoustic and visual information. Selection of appropriate diphone units to synthesize a given text string is based on the minimization of a weighted linear combination of four costs that reflect linguistic, acoustic, and visual considerations. We present initial work toward a method to determine a...
Multi attribute decision making (MADM) is a dynamic idea that has been established in line with creating techniques and methods to enable a decision maker to solve complicated problems which are composed of several contradictory, different factors. One of the most attractive techniques in practice is additive rank order method to com-pare ordinal evaluations of actions on criterion which is cal...
Performance analysis and ranking of provincial gas companies in the presence of undesirable products
Data envelopment analisys is a most frequently applied technique in the field of operations research that has attracted considerable attention among researchers. In this paper a performance evaluation model is proposed to analyse the relative efficiency of a set of decision making units when there are both, desirable and undesirable outputs. Managerial disposability assumption is used to handle...
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 extreme efficient DMUs, cross efficiency can rank all DMUs, even non-extreme ones. However, sinc...
