Two Mathematical Models for Railway Crew Scheduling Problem
Railway crew scheduling problem is a substantial part of the railway transportation planning, which aims to find the optimal combination of the trip sequences (pairings), and assign them to the crew complements. In this problem, each trip must be covered by at least one pairing. The multiple-covered trips lead to impose useless transfers called “transitions”. In this study, a new ma...
متن کاملA Comprehensive Approach for Railway Crew Scheduling Problem (Case Study: Iranian Railway Network)
The aim of this study is to propose a comprehensive approach for handling the crew scheduling problem in the railway systems. In this approach, the information of different railway trips are considered as input and the problem is divided to three separated phases. In phase I, we generate all feasible sequences of the trips, which are named as the pairings. A depth-first search algorithm is deve...
متن کاملImprovement of Column Generation Method for Railway Crew Scheduling Problems
The railway crew scheduling problem is to determine an optimal crew assignment to minimize the number of crews required to cover all of railway assignment satisfying several crew working constraints. The problem can be formulated as a huge set covering problem. Column generation method is commonly used to solve the railway crew scheduling problem. Conventional column generation method has a sho...
متن کاملCase studies of successful train crew scheduling optimisation
UK has a large and complex passenger rail network divided into a number of franchises. Crew scheduling, one of the last stages of operations planning before services go live, is mission critical to the train operating companies, which would feel the pain of manual scheduling. As far as the author is aware, attempts by these companies to adopt an automatic optimizing train crew scheduling system...
متن کاملRailway 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...
