during the last years, the concept of input congestion and technical ineff- ciency in data envelopment analysis (dea), have been investigated by manyresearchers. the motivation of this paper is to present models which obtain thedecreased output value due to input congestion and technical ineciency. more-over, we extend the models to estimate input congestion, technical ineciencyand output red...

Due to rapid technological innovation and global competitiveness, the component cost, the selling price and the demand rate of Hi-tech industries (such as computers and communication consumer’s products) usually decline significantly with time. From a practical viewpoint, there is a need to develop a replenishing policy with finite horizon when the component cost, the selling price and the dema...

Technical analysis is the forecasting of future price movement based on an examination of past prices. Some scientist found that the study of historical prices cannot predict future prices. In this research we intend to study which technical analysis tool is better for prediction of future price movement, for this purpose we are studying two the most strongest technical analysis tools is called...
