| After natural disasters and unexpected events, one of the most vital actions of disaster response phase is to transport evacuees from disaster areas to safe places. In this paper, decisions of the location of shelters and routing and scheduling of relief vehicles at the same time are modeled for a two-level network including depots of vehicles, affected areas, and shelters. In the evacuation operation, the possibility of servicing to evacuees in each affected area by several vehicles, existence of multiple depots of heterogeneous vehicles and time window constraints are considered. To solve the proposed model and demonstrate its efficiency, a numerical example was solved by exact method, and it was done the sensitivity analysis on the problem main parameters. Results show that the number of shelters to locate evacuees and capacity of relief vehicles effects on total times for vehicles to get to affected areas and shelters. | ||

| چکیده [English] | ||
| پس از وقوع بلایای طبیعی و حوادث غیرمترقبه، یکی از مهم‌ترین عملیات امدادی، تخلیۀ افراد سالم از مناطق حادثه‌دیده به مکان‌های امن است. در این پژوهش، شبکهای دوسطحی متشکل از انبارهای وسایل، مناطق حادثه‌دیده و پناهگاه‌ها درنظر گرفته شده و با ارائۀ یک مدل جدید، به مکان‌یابی پناهگاه‌ها و مسیریابی و زمان‌بندی حرکت وسایل امدادی پرداخته شده است. در فرایند تخلیۀ افراد سالم، امکان برآورد تقاضا در هر منطقۀ حادثه‌دیده با چندین وسیله، انبارهای چندگانه و محدودیت پنجره‌های زمانی درنظر گرفته میشود. برای حل مدل پیشنهادی و نشاندادن کارایی آن، یک مثال عددی با روش دقیق حل شد و تحلیل حساسیت‌های مختلف بر پارامترهای تأثیرگذار مسئله انجام گرفت. نتایج نشان می‌دهد تعداد مکان‌ها برای اسکان بازماندگان و ظرفیت وسایل امدادی، بر کل زمان رسیدن وسایل به مناطق آسیب‌دیده و پناهگاه‌ها تأثیرگذار است. | ||
