MAXIMISING COST-EFFECTIVENESS OF EUROPEAN RAIL TRAFFIC MANAGEMENT SYSTEM (ERTMS) BY OPTIMISING MAINTENANCE POLICY

摘要

European Rail Traffic Management System (ERTMS) is a major venture by European Union in order to create interoperable railway network within Europe. Manufacturers of ERTMS strive to attain a competitive edge by demonstrating the efficiency of their systems. Costeffectiveness is one of the significant ways to address efficiency of the system which deals in maximising availability and minimising life cycle cost of the system over the system life cycle. Maximum cost-effectiveness of a system can be achieved through various techniques with maintenance policy optimisation being one of the important means. This paper demonstrates the optimisation of maintenance policy of a sub-system of ERTMS so as to achieve maximum cost-effectiveness
