Currently Sambre-Avesnois Hospital doesn't have a system to generate schedule taking into account operating theatre constraints and objectives. This workload is a part of the surgical unit supervisor's responsibilities. It is done manually, which makes it more susceptible to errors and can be extremely timeconsuming. However, the surgical unit supervisor has already other daily responsibilities which are as important as this task. Thus, our work handles the conception and the realization of a computer-aided which schedules surgeries by optimizing the program of the unit. Firstly, we have made an analogy between the functioning of the surgical unit and the flexible job shop problem. And so the idea of conceive a scheduling tool using an evolutionary approach was born. Furthermore we found a codification close to the reality. Then we implemented the various adapted genetic operators and realized a simulation with Java for one day in the surgical unit. We also made a comparative study with the static method currently used in the Sambre-Avesnois Hospital to demonstrate the efficiency of our model.
