In this research, we are interested in the daily scheduling problem with a strategy named "open scheduling strategy". Considering this strategy all operating rooms are available for all possible surgical cases and their time blocks are not reserved for specific surgeons, i.e., once a set of surgical cases are assigned to one day one or several weeks in advance, we schedule these surgical cases into a set of multifunctional operating rooms so as to fulfill the restrictions of the recovery room and surgeons and aim at minimizing the daily operating cost of the operating theatre. Consequently, the objective is to minimize the weighted sum of occupation time of the recovery room and that of operating rooms. In addition, if there exist several daily operating programs with the same objective value, an auxiliary criterion, the weighed sum of occupation time of the recovery room and the average occupation time of operating rooms, is applied in order to find the final solution In this research

Un bloc opératoire se compose de deux parties importantes : les salles d'opération et la salle de réveil (SSPI). Il constitue non seulement le secteur le plus important et le plus coûteux dans la majorité des hôpitaux, mais il est également le service le plus complexe à gérer et à planifier, étant donné les nombreux aléas, le nombre élevé d'acteurs, la difficulté de standardisation et de coordination des interventions chirurgicales. Dans cette recherche, nous visons à construire un programme opératoire journalier pour un bloc opératoire constitué de plusieurs salles d'opération identiques et de lits communs en SSPI en prenant en compte le cas où les lits en SSPI ne sont pas toujours disponibles. Nous nous plaçons dans le contexte d'une stratégie de programmation opératoire d'"open-scheduling". Ce problème est résolu au moyen d'une méthode tabou.

This paper deals with the application of statistical tests to Multi-Criteria Decision Making problems in the context of scheduling nonpreemptable jobs. This study synthesizes the results of the application of our framework to a real-life, highly constrained, discrete-continuous problem. The purpose of this paper is to compare the solutions of five scheduling strategies so as to select the most adequate scheduling strategy when considering the decision-maker's preferences and the economic context. The solutions are ranked via a lexicographical sort or a multicriteria analysis and validated by parametric and non-parametric statistical tests.

Considering that the health sector stands out specifically because of the critical nature of the service levels associated with logistical activities: the lack of an item or a drug in the operating room could, for example, greatly influence the work performed by health care workers and threaten the health of a patient. The quality of support services must be maintained. What should be noticed when some practical ideas of industrial logistic systems are applied to the hospital one? In order to answer those questions, in this paper, we explored not only the analogs but also the difference between the industrial logistic system and the patient support system in the operating theatre. The objective is to introduce the practical ideas of logistic management into hospitals so as to enable the evaluation of the current process, which aims to decrease delays and increase logistic service effectiveness and productivity.
