Iranian Railway System Performance Analysis Using Computer Simulation and Data Envelopment Analysis Methods
In this paper, a discrete event simulation model of Iranian railway system is used for analyzing performance of the system in freight sector. The model analysis shows more sensitivity of the system on loading and unloading facilities than on number of wagons and locomotives. System optimization through simulation optimization technique, shows that more than 4% of all wagons available in the n...

متن کاملData Envelopment Analysis with LINGO Modeling for Technical Educational Group of an Organization
Data Envelopment Analysis (DEA) was developed to help compare the relative performance of decision-making units. It is a non-parametric method for performing frontier analysis. It uses linear programming to estimate the efficiency of multiple decision-making units and it is commonly used in production, management and economics [3]. DEA generates an efficiency score between 0 and 1 for each unit...
متن کاملData Analysis and Knowledge Extraction in Educational Data Mining (EDM)
While the field of educational data mining (EDM) has generated many innovations for improving educational software and student learning, the mining of student data has recently come under a great deal of scrutiny. Many stakeholder groups, including public officials, media outlets, and parents, have voiced concern over the privacy of student data and their efforts have garnered national attentio...

متن کاملComputer Analysis of X-Band Radar Data
Dual polarized X-Band Synthetic Aperture Radar (SAR) data were obtained for a test site in South Carolina containing a variety of forest and agricultural cover types, as well as water and urban areas. The optically correlated images were digitized with a scanning microdensitometer using a 40 ~m aperture. Digi tal registration of the two polarizations was more difficult than anticipated due to g...
