Train crew management involves the development of a duty timetable for each of the drivers (crew) to cover a given train timetable in a rail transport organization. This duty timetable is spread over a certain period, known as the roster planning horizon. Train crew management may arise either from the planning stage, when the total number of crew and crew distributions are to be determined, or...

In 2003, Hamilton Health Sciences embarked on an initiative to improve and standardize nursing schedules and scheduling practices. The scheduling project was one of several initiatives undertaken by a corporate-wide Nursing Resource Group established to enhance the work environment and patient care and to ensure appropriate utilization of nursing resources across the organization's five hospita...

The real-life scheduling problems are often over-constrained, and there is often one intractable case where unexpected events are added and a sudden change is required. In this paper, we describe such problems as the Dynamic Valued Constraint Satisfaction Problem (DyVCSP). In DyVCSP, although the previous schedule would be modified when there is some change, the new schedule should be similar t...

The main challenge of Nurse Scheduling Problem (NSP)is designing a nurse schedule that satisfies nurses preferences at minimal cost violating the soft constraints. This makes NSP an NP-hard problem with no perfect solution yet. In this study, two meta-heuristics procedures: Genetic Algorithm (GA) and Tabu Search (TS) memory was applied for development automatic hospital scheduling system (GATS_...
