چکیده

با افزایش بلایای طبیعی، نیاز جامعه به خدمات سلامت‌محور افزایش چشمگیری داشته است. در هنگام وقوع حادثه ارائه خدمات در زمان مناسب و به موقع یکی از ضروری‌ترین اقدامات ممکن می‌باشد. به همین منظور در ابتدا باید وضعیت مصدومان مشخص شده و درمان آغاز شود و در صورت افزایش وخامت حال مصدومان، این افراد در کمترین زمان به مراکز درمانی انتقال یابند. به همین منظور مراکز درمانی باید در مکان‌هایی با دسترسی مناسب قرار گیرند. از طرفی یکی دیگر از اقدامات مهم در زمان وقوع حادثه، ارسال دارو و اقلام پزشکی در زمان مناسب جهت درمان مصدومان می‌باشد. بنابراین یک مدل ریاضی مکان‌یابی و موجودی به منظور ارائه خدمات بهتر با هدف کمینه‌سازی هزینه-ها‌ی مربوط به مکان‌یابی و موجودی سیستم‌های سلامت‌محور ارایه گردیده و سپس جهت تحلیل مسأله موردنظر، از روش‌های حل دقیق و روش فراابتکاری الگوریتم ژنتیک برای 20 مسأله پیشنهادی بهره جستیم. نتایج بیانگر آن است که در ابعاد بزرگ، الگوریتم ژنتیک می‌تواند الگوریتم کارایی برای حل مسئله این تحقیق باشد.

چکیده [English]

Given the increase of natural disasters, the community's need for health services has increased dramatically. Firstly, the condition of the injured people should be determined and then the treatment should be start, and in the event of increasing in the severity of the injured, these people should be transfer to the hospitals in the shortest possible time. On the other hand, another essential measure at the time of the accident is to send medicines and medical items at the appropriate time for treatment of injured. In this regard, we follow to design an emergency relief supply chain network including suppliers of medical items, treatment center, warehouses, and disaster points. Therefore, a location and inventory mathematical modeling is proposed to provide better services with the goal of minimizing the costs associated with locating and inventory of health systems. Thenو, to analyze and optimize the problem, proposed some numerical example and genetic algorithm.
