Abstract:Railway maintenance works are performed to reduce the probability of the occurrence of a failure on the components of the railway infrastructure. The scheduling of maintenance work is quite important in supporting the normal daily operation of the railway. By proper maintenance scheduling, operational hindrance can be minimized and contractors are given space to execute maintenance activities exible. This thesis aims to optimize the maintenance schedules for both train operators and maintenance contractors, by considering hindrance and exibility for both stakeholders respectively. This thesis achieved this by modelling important factors contributing to both objectives and all relevant constraints in a multi-objective optimization problem. The important factors contributing to the objectives were obtained by interviewing experts in the field and stakeholders. The most important factors found contributing to hindrance were detouring, rescheduling trains, and relocating parked stock. In order to model detouring of trains, two path finding algorithms were modified to consider physical train travel limitations. The most important factors found contributing to exibility were the number of maintenance slots and the spread of these slots.
