A Constraint-directed Local Search Approach to Nurse Rostering Problems
In this paper, we investigate the hybridization of constraint programming and local search techniques within a large neighbourhood search scheme for solving highly constrained nurse rostering problems. As identified by the research, a crucial part of the large neighbourhood search is the selection of the fragment (neighbourhood, i.e. the set of variables), to be relaxed and re-optimized iterati...
متن کاملA Constraint Programming and Hybrid Approach to Nurse Rostering Problems
This paper describes a decision support methodologies for nurse rostering problem in a modern hospital environment. In particular, it is very important to efficiently utilise time and effort, to evenly balance the workload among people and to attempt to satisfy personnel preference. We presented a complete model to formulate all the complex real-world constraints, solution approach and Hybrid a...
متن کاملA Hybrid Constraint Programming Approach for Nurse Rostering Problems
Due to the complexity of nurse rostering problems (NRPs), Constraint Programming (CP) approaches on their own have shown to be ineffective in solving these highly constrained problems. We investigate a two-stage hybrid CP approach on real world benchmark NRPs. In the first stage, a constraint satisfaction model is used to generate weekly rosters consist of high quality shift sequences satisfyin...
متن کاملVariable Neighbourhood Search for Nurse Rostering Problems
Nurse rostering problems consist of assigning varying tasks, represented as shift types, to hospital personnel with different skills and work regulations. We want to satisfy as many constraints and personal preferences as possible while constructing a schedule which meets the personnel requirements of the hospital over a predefined planning period. Real world situations are often so constrained...
متن کاملA Hyperheuristic Approach to Belgian Nurse Rostering Problems
The nurse rostering problem involves the assignment of shifts to nurses with respect to several constraints like workload, legal restrictions, and contractual agreements [9]. The complexity of the problem attracts many researchers around the world. Since the regulations, requirements, and agreements differ from country to country, the models and solution methods differ as well [9]. The solution...
