iranian railway system performance analysis using computer simulation and data envelopment analysis methods

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...

Productivity Management in Iranian Railway by Data Envelopment Analysis

Study of various transportation indicators could be an appropriate criterion in evaluating the performance of the existing railways throughout the globe. This study was carried out to investigate the performance of rolling stock of Iranian railway using productivity analysis. In order to solve the problems, some solutions were provided by productivity management cycle steps. At the first step, ...

Failure Mode and Effects Analysis Using Data Envelopment Analysis

Data envelopment analysis of reservoir system performance

In long-term performance analyses of water systems with surface reservoirs for different operating scenarios, the analyst (or decision maker) is faced with two connected problems: (1) how to handle the extensive output of the simulation model and derive information on the scenarios scores for a prescribed set of performance criteria, and (2) how to compare scenarios in a multi-criterial sense w...

Description and Analysis of Performance, Potential and Efficiency of Iranian football pro- league by Data Envelopment Analysis

In the case of football it could be argued that the purpose of teams is to win the competitions in which they participated. However, the assessment of  football teams from the efficiency aspect would be relevant in judging whether the results have been obtained without waste. The purpose of this research is to compare  and  analysis of league ranking with  Potential and efficiency ranking. The ...

Efficient location by using data envelopment analysis

So far, many types of location models have been developed to find optimal spatial patterns according to different spatial metrics such as cost, coverage and availability.  The initial focus of these models is on the location availability of service providers and demand estimates, and some of these models are within the framework of multi-objective programming models.  After the advent of scienc...
