Railway Crew Rescheduling with Retiming
Railway operations are disrupted frequently, e.g. the Dutch railway network experiences about three large disruptions per day on average. In such a disrupted situation railway operators need to quickly adjust their resource schedules. Nowadays, the timetable, the rolling stock and the crew schedule are recovered in a sequential way. In this paper, we model and solve the crew rescheduling proble...
متن کاملColumn Generation with Dynamic Duty Selection for Railway Crew Rescheduling
The Dutch railway network experiences about three large disruptions per day on average. In this paper, we present an algorithm to reschedule the crews when such a disruption occurs. The algorithm is based on column generation techniques combined with Lagrangian heuristics. Since the number of duties is very large in practical instances, we first define a core problem of tractable size. If some ...
متن کاملAlgorithms for railway crew management
Crew management is concerned with building the work schedules of crews needed to cover a planned timetable. This is a well-known problem in Operations Research and has been historically associated with airlines and mass-transit companies. More recently, railway applications have also come on the scene, especially in Europe. In practice, the overall crew management problem is decomposed into two...
متن کاملMathematical Rescheduling Models for Railway Services
This paper presents the review of past studies concerning mathematical models for rescheduling passenger railway services, as part of delay management in the occurrence of railway disruption. Many past mathematical models highlighted were aimed at minimizing the service delays experienced by passengers during service disruptions. Integer programming (IP) and mixed-integer programming (MIP) mode...
متن کاملConstraints Based Effective railway Rescheduling System
Delays of trains occur owing to accidents, bad weather conditions, vehicle troubles, etc. Trains run according to the departure order of trains at each station (called "SOT") in the scheduled plan. Therefore, a delay of a train delays its succeeding train, which may result in a chain reaction of delays and confusion arises to the whole network finally. The rescheduling needs to adjust SOT and t...
