Development of Iranian Railway Track Maintenance Management System

Development of an optimized strategy for the maintenance of Iranian railway track maintenance in a form of management system was made in this research. Through reviewing the current maintenance management system in the USA, Europe and Asia as well as investigating the characteristics of railway structure and current maintenance approaches in Iran, a new algorithm was made in order to improve efficiency of maintenance decision system and maintenance planning in Iranian railway industry. The practicability and reliability of the new maintenance algorithm (model) were evaluated by applying the new proposed algorithm in a railway line in Tehran province. It was shown that the new proposed maintenance management system (algorithm) is effective in providing an optimized maintenance strategies and plans. It was also shown that track operation can be evaluated by sensitivity analyses of the proposed model.
