Identify and prioritize factors affecting the efficient use of fleet capacity rail

Development of transportation infrastructures is one of the basic requirements of each country. The criteria such as speed, comfort, safety, reliability and ready to work transportation system are the most important indexes for the assessment of the systems by passengers and the goods owners for selecting the suitable transportation. Considering the high cost of investment for purchasing fleet and building the new tracks and ever- increasing demands, the best using of rail capacities is very important.
In this paper first the components affected on productivity in different section have been identified by reviewing the literature, field studies and interview with the experts in the different rail sections. These components have been determined in the areas of infrastructure, fleet, mobility, commercial and human resources. A questionnaire based on the effective criteria and components is prepared and distributed between the experts in this field. After collecting the questionnaires, the statistics test, the Cronbach's alpha, distribution normality, data statistical description have been made and by using the one- sample t test the correctness of the proposed hypothesis has been proved. Finally the prioritization of the factors effected on the best utilization of the rail fleet capacity have been submitted by using the linear assignment of multi- criteria decision making methods.
