چکیده

مدیرت بحران در هنگام وقوع بلایا جهت کاهش حداکثری خسارات و تلفات از اهمیت بسیار بالایی برخوردار است. از بعد مدیریت بحران، لجستیک امداد جایگاه خاصی دارد، زیرا یکی از نیازهای مهم در مدیریت بحران قابلیت نقل و انتقال سریع نیروهای امدادی و اقلام مورد نیاز به منطقه بحران زده و نیز خروج آسیب­دید­گان و افراد در هنگام و بعد از وقوع بحران است. در این پژوهش به مکانیابی، مسیریابی و توزیع کالاهای امدادی در شرایط وقوع زلزله پرداخته می­شود. بیشینه کردن احتمال عبور موفق از مسیرها، کمینه کردن هزینه­های امدادی و کمینه‌‌سازی مازاد و کمبود پرسنل امدادی انتقالی به مناطق آسیب دیده‌ از جمله اهداف این پژوهش می­باشد. مدل ریاضی پیشنهادی با رویکرد محدودیت اپسیلون توسعه­ یافته و با استفاده از نرم افزار گمز برای مطالعه موردی منطقه 11 تهران حل گردیده است. در ­نظر گرفتن انواع مجروحین شامل مجروحان سرپایی و مجروحان شدید، همچنین بی­خانمان­ها و پرسنل امداد بصورت همزمان و مدل­سازی ریاضی سه هدفه، چندکالایی، چند وسیله­ای با ملاحظات عدم قطعیت بصورت سناریویی از جمله نوآوری­های این پژوهش بشمار می­رود.

چکیده [English]

Crisis management holds significant importance during the occurrence of disasters to ensure  maximum reduction in damages and casualties. From a crisis management perspective, emergency logistics occupy a special position because swift transportation of relief personnel and necessary supplies to the affected area, as well as the evacuation of the injured and others during and after a disaster, are amongst the critical needs. This research addresses the locating, routing, and        distribution of emergency supplies in the context of earthquakes. Objectives of this research include maximizing the probability of successfully navigating routes, minimizing emergency response costs, and reducing discrepancies in the allocation of relief personnel to affected regions. The proposed mathematical model, enhanced with an augmented epsilon constraint approach, has been solved using the GAMS software for a case study of Tehran's 11th district. The consideration of various types of injured individuals, including those with minor injuries and those in critical condition, as well as the homeless and relief workers in a concurrent manner, and the development of a three-objective, multi-commodity, multi-vehicle mathematical model with scenarios incorporating uncertainty, are among the innovations of this study.
