چکیده

طراحی تسهیلات سلامت از دیرباز یکی از مهم­ترین موضوع­های مورد توجه برنامه­ریزان حوزه سلامت بوده است. در هنگام بحران به‌منظور امدادرسانی به مصدومان، شبکه سلامت شامل مجموعه­ای از درمانگاه­ها و بیمارستان­ها فعالیت می­کند. هدف این تحقیق تشکیل ساختاری سلسله مراتبی در راستای ارائه خدمت­ به مصدومان با افزودن مراکز اضطرار موقت درمان به شبکه مزبور، برای جلوگیری از هجوم و ازدحام مصدومان در دو سطح درمانگاه­ها و بیمارستان­ها است. در این مقاله از روش برنامه­ریزی چند هدفِ خطی آمیخته با اعداد صحیح استفاده شده است. برای حل مدل، نرم­افزار بهینه­ساز GAMS، به‌کاررفته است. نتایج پژوهش نشان می­دهد که مدل سلسله مراتبی نسبت به مدل ساده، سبب کاهش ازدحام جمعیت در بیمارستان­ها و درمانگاه­ها در هنگام بحران می­شود. در این مدل ضمن بهینه شدن هزینه ایجاد مراکز درمان اضطرار موقت، زمان و مسافت طی شده برای انتقال مصدومان کمینه شده است. با استفاده از مدل پیشنهادی بهترین مکان‌ها جهت تأسیس مراکز اضطرار درمان از بین نقاط منتخب و سپس نحوه تخصیص بهینه مصدومان به‌طور سلسله مراتبی از نواحی شهری به مراکز درمان اضطرار و ازآنجا به درمانگاه­ها و درنهایت به بیمارستان‌ها مشخص می‌شود.

چکیده [English]

Designing health facilities has long been one of the most important issues for health planners. During the disaster, the health network, which includes a set of clinics and hospitals, are activated to help the injured people. The purpose of this study is to add temporary emergency treatment centers to the network, in order to prevent the influx and overcrowding at the two levels of clinics and hospitals during the disaster and to create a hierarchical structure to serve the casualties. In this paper, a mixed linear integer programming with integers is used. Gams optimization software was used to solve the model. The results showed that the hierarchical model reduced the crowding in hospitals and clinics during disaster compared to the simple model. In this model, while optimizing the cost of setting up emergency treatment centers, the time and distance traveled for casualties are minimized. Using the proposed model of the best places to establish emergency treatment centers among the selected candidate points and then the optimal allocation of injuries is determined hierarchically from city areas to temporary emergency treatment centers, and from there to clinics and ultimately to hospitals.
