This article briefly surveys the current state-of-the-art on ship management in maritime transportation. It covers three most important aspects of ship management: crew scheduling, maintenance scheduling, and spare part management.

In this paper, we deal with the crew assignment problem, which is a subproblem of the airline crew scheduling problem. The aim of the crew assignment problem is the optimal allocation of a given set of crew pairings to crew members, in a way that a set of constraints is satis ed. The optimality criterion we employ in this work requires the ight time fair distribution among all crew members. Thi...

The Crew Rostering Problem considers the assignment of the crew staff to a set of pairings covering all the scheduled flights so that operations costs are minimized while its solution must meet hard constraints resulting from the safety regulations of Civil Aviation as well as from the airlines’ internal agreements. Another goal is of the highest interest for airlines: since the overall satisfa...

In this paper, we discuss the dynamic vehicle and crew scheduling problem and we propose a solution approach consisting of solving a sequence of optimization problems. Furthermore, we explain why it is useful to consider such a dynamic approach and compare it with a static one. Moreover, we perform a sensitivity analysis on our main assumption that the travel times of the trips are known exactl...

Railway crew scheduling problem is the process of allocating train services to the crew duties based on the published train timetable while satisfying operational and contractual requirements. The problem is restricted by many constraints and it belongs to the class of NPhard. In this paper, we develop a mathematical model for railway crew scheduling with the aim of minimising the number of cre...

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...
