A Bi-Objective Paediatric Operating Theater Scheduling

In this paper, a bi- objective Operating Theater scheduling is proposed. The problem subject to order and assignment constraints. first the minimization of operating theater opening total time also called makespan in manufacturing systems while second maximize constraints satisfaction. considered as two-stage hybrid flow shop with blocking. Several metaheuristics are compared: firefly algorithm, bats particles swarm optimization local search. addition care specific qualitative quantitative parameters, average deviation from lower bound used confirm effectiveness methods. implementation done on paediatric hospital Oran when it properly improperly sized.
