SIMULATION AND INTEGER PROGRAMMING APPROACH FOR EFFICIENT SHIFT DESIGN

摘要

Operation research approaches and heuristics are often used in the staff organization literature. The main hypothesis considered by shift scheduling approaches is that the workload variability is negligible. Faced to a real organization problem of cleaning staff in a multidisciplinary surgical suite, the lack of exploratory approaches adapted to a context of variable activity has been observed. The purpose of this paper is to implement a hybrid approach combining integer linear programming and a simulation model for assessing performance. Finally, the hybrid approach can save 30% of the cost compared to the solution given by operation research approach alone.
