چکیده

اثرات ویرانگر بلایای طبیعی، اهمیت لجستیک و برنامه‌ریزی منابع انسانی را در مراحل قبل و بعد از بحران نشان می‌دهد. هنگام بروز بحران به ‌منظور امدادرسانی سریع، شبکه سلسله ‌مراتبی سلامت که شامل درمانگاه‌ها و بیمارستان‌ها است، فعال می‌شود. در این پژوهش با استفاده از مدل ریاضی مختلط عدد صحیح و با درنظرگرفتن موقعیت فعلی بیمارستان‌ها و درمانگاه‌ها، مکان‌های بهینه‌ای با عنوان «مراکز درمان موقت» تعیین و نحوه تخصیص بهینه مصدومان از ناحیه‌های شهری به این مراکز پیشنهاد می‌شود. انتخاب مکان‌های بهینه، تخصیص بهینه سلسله‌مراتبی مصدومان، تعیین ظرفیت بهینه مراکز پذیرش، تعیین نقاط پشتیبان برای مراکز درمان موقت در قالب یک مدل تلفیقی ریاضی و شبیه‌سازی به‌صورت هم‌زمان از نوآوری‌های این پژوهش است. به کمک مدل شبیه‌سازی لحظه بروز بحران و فرایند امداد و نجات شبیه‌سازی‌شده و با رویکرد بهینه‌سازی مبتنی بر شبیه‌سازی، ظرفیت بهینه مراکز موقت و اصلاح ظرفیت درمانگاه‌ها و بیمارستان‌های فعلی انجام شده است. نتایج پژوهش نشان می‌دهد مدل سلسله‌ مراتبی مکان‌یابی–تخصیص، بهینه‌سازی ظرفیت سبب کاهش ازدحام مصدومان و کاهش هزینه و زمان درمان می‌شود.

چکیده [English]

The destructive impact of natural disasters emphasizes the importance of logistics and human resource planning in the pre- and post- disaster periods. In the event of a disaster, in order to provide immediate relief, the Health Hierarchical Network, which includes clinics and hospitals, will be activated. In this paper, using a mixed integer mathematical model and assuming the current location of hospitals and clinics, optimal locations are determined as temporary treatment emergency centers and the optimal allocation of casualties from urban areas to these centers and then clinics and hospitals are recommended in disaster. Using the simulation model, the moment of disaster and the rescue process were simulated and then the optimization approach was adopted based on simulating the optimal capacity of temporary centers and improving the capacity of current centers and hospitals. The results of the study show that the hierarchical model of location allocation of capacity optimization reduces the density of casualties, costs and treatment time in disaster.
