A DYNAMIC APPROACH FOR PLANNING PREVENTIVE RAILWAY MAINTENANCE ACTIVITIES

Abstract

This paper provides some useful methods for finding optimal track possession intervals for carrying out preventive maintenance works. The objective is to minimize the inconvenience fro the train operators and the infrastructure possession time. In these models the train free periods are mostly used for this purpose, name the hours between two consecutive train operations. This approach can be useful for some European railway companies for carrying out preventive maintenance works.
