The scheduling problem in surgery is difficult because,in addition of the planning of the operating rooms which are the most expensive resources in hospitals,each surgery requires a combination of human and material resources.In this paper,the authors address a surgery scheduling problem which arises in operated health care facility.Moreover,the authors consider simultaneously materiel and human resources.This problem is a three-stages flow shop scheduling environment.The first stage(ward)contains a limited number of resources of the same type(beds);The second stage contains different resources with limited capacity(operating rooms,surgeons,nurses,anesthesiologists)and the third stage contains a limited number of recovery beds.There is also a limited number of transporters(porters)between the ward and the other stages.The objective of the problem is to minimize the completion time of the last patient(makespan).The authors formulate this NP-Hard problem in a mixed integer programming model and conduct computational experiments to evaluate the performance of the proposed model.
