برنامه‌ريزي پيشنگرانه-واكنشي هفتگي جراحي بيماران در شبكه‌اي از بيمارستان‌ها

The entry of patients into the planning or not paying attention to the plans made causes the planning of the operating room to face challenges, if these challenges may make the planning of the operating room far from reality. According to the analysis of various issues in the field of planning and operation timing, it is evident that predicting disorders is very valuable for hospitals. Also, organizations seek to share resources instead of owning them. Hospitals also share patients and resources in a network. Patients should be assigned to hospitals and functional rooms based on the plans and schedules taken. To properly assign patients to hospitals and operating rooms, several factors must be considered, which complicate the planning and scheduling process. Including various cases of people, surgeons, etc., also to address the issue of patient scheduling, in receiving resources such as qualified rooms, rare and expensive equipment, human resources (nurses and surgeons) need to perform any operation, in treatment to treat patients It should be considered in the relevant section of each hospital, and it is necessary to assign patients to hospitals for treatment according to these limitations. One of the important factors that should be taken into consideration is the correct and timely management of disruptions caused by the arrival of emergency patients and planned cancellations. Considering a part of the operating room for emergency patients (keeping a part of the operating room time empty) and predicting the cancellation rate of patients seems to improve the use of the operating room. As a result, it is very important to provide a suitable planning model by considering the practical choice of prioritization, capacity in nurses, downstream resources and unplanned forecasting and at the same time providing a solution to deal with preventing forecasting. The subject of weekly surgical planning of patients considering the cancellation disorders and the arrival of patients in a network of hospitals is discussed with a block strategy and two predictive-reactive mathematical models are presented. In such a way that a schedule is planned proactively, taking into account the possibility of emergency disease and cancellation of surgery, and in cases where more emergency patients are admitted than expected or surgery is canceled. Reactive timing unselected surgery is performed. The goal in pre-planning has been to digitize the set time and minimize the beds divided between the departments of a hospital, and the goal in reactive scheduling has been to minimize the amount of changes from the initial plan and the current plan in addition to proactive scheduling. Is To solve the model, the data is randomly generated and eva‎luated. Finally, an analysis was performed on the influential parameters, which showed the importance of determining the appropriate value for predicting the arrival of emergency patients and the cancellation rate of patientsʹ surgery, and also showed the importance of the available capacity for nurses and inpatient beds. which shows that he understands the advantage of sharing hospitals well.
