چکیده

با تغییرات اکولوژیکی، تقاضا برای خدمات اضطراری و اقلام امدادی در شرایط بحران، افزایش یافته است. در این مقاله، مدل یک‌پارچه‌یی از مکان‌یابی و تخصیص تسهیلات پشتیبان در دو بخش اسکان و تأمین و در دو فاز آمادگی و پاسخ به منظور افزایش قابلیت اطمینان زنجیره‌ی بحران ارائه شده است. مدل ریاضی ارائه شده، مدلی چندهدفه و سناریومحور است که پس از مقایسه‌ی نتایج روش‌های حل چندهدفه، به روش نرمال‌سازی و تجمیع توابع هدف، حل می‌شود. نتایج تحقیق نشان می‌دهد استفاده‌ی ترکیبی از راهبردهای حمایتی اعم از تسهیلات پشتیبان در بحران سیل امری حیاتی است. همچنین با معرفی بحران سیل در شهر قم به عنوان مطالعه‌ی موردی، راهکارهایی پیشنهاد شده است که ضمن حل مشکل کمبود فضای احداث در مناطق متراکم مرکزی، با صرف کم‌ترین هزینه، میزان خسارات در بلندمدت را تا سطح قابل توجهی کاهش می‌دهد.
