Abstract
BACKGROUND
This research studies a medical staff scheduling problem, which includes government regulations and hospital regulations (hard constraints) and the medical staff's preferences (soft constraints).
OBJECTIVE
The objective function is to minimize the violations (or dissatisfaction) of medical staff's preferences.
METHODS
This study develops three variants of the three-phase modified bat algorithms (BAs), named BA1, BA2, and BA3, in order to satisfy the hard constraints, minimize the dissatisfaction of the medical staff and balance the workload of the medical staff. To ensure workload balance, this study balances the workload among medical staff without increasing the objective function values.
RESULTS
Based on the numerical results, the BA3 outperforms the BA1, BA2, and particle swarm optimization (PSO). The robustness of the BA1, BA2, and BA3 is verified. Finally, conclusions are drawn, and directions for future research are highlighted.
CONCLUSIONS
The framework of this research can be used as a reference for other hospitals seeking to determine their future medical staff schedule.
