There is an interest in search algorithms capable of learning and adapting their behaviour while solving a given problem. A hyper-heuristic operates on a set of predefined heuristics and applies a machine learning technique to predict which heuristic is the most effective to apply at a given point in time. Thompson Sampling is a machine learning mechanism interacting with the search environment to...
Hyper-heuristic (HH) is a higher level heuristic to choose from a set of heuristics applicable for the problem on hand. In this paper, a Harmony Search-based Hyper-heuristic (HSHH) approach is tested in solving nurse rostering problems (NRP). NRP is a complex scheduling problem of assigning given shifts to a given nurses. We test the proposed method by using the First International Nurse Rostering...
Nurse scheduling is the process of allocating shifts for nurses by specifying the sequence of shifts for each nurse in the scheduling period. Generating good schedules for nurses is a very difficult and tedious problem due to the operational of hospital that runs 24 hours a day and 7 days a week. Schedule that has work shifts is a big influence on the level of stress and fatigue for nurses, as well...
Decision-support tools are essential to assist planners when scheduling operations in complex systems. It is critical that real-world operational and workforce details be taken into account when constructing models of the system, so as to ensure the feasibility and implementability of the final solution. However, the level of detail can greatly impact the tractability of the model - for example, increased...
The employee timetabling problem (ETP) is concerned with assigning a number of employees into a given set of shifts over a fixed period of time, e.g. a week, while meeting the employee's preferences and organizational work regulations. The problem also attempts to optimize the performance criteria and distribute the shifts equally among the employees. The problem is considered a classical NP-complete...
Although of particular importance for many real-life applications, restrictions to drivers' working hours have only received very little attention in the vehicle routing literature. Regulations regarding drivers' working hours often have a big impact on total travel times, i.e. the time required for driving, breaks, and rest periods. In this paper we describe the regulations for drivers' working hours...
