چکیده

در زمان وقوع بلایای طبیعی و انسان‌ساز، تامین برخی اقلام که ارتباط مستقیم بازندگی انسان‌ها دارند، از اهمیت بالایی برخوردارند. در جهان واقعی سیستم‌های عرضه با اختلالات بسیاری در تسهیلات خود روبه‌رو هستند و از کار افتادن تسهیلات منجر به عدم تامین به‌موقع می‌شود و اهمیت این موضوع در سیستم تامین خون بیشتر آشکار می‌شود. در این مقاله، مدلی چندهدفه برای مکان‌یابی تسهیلات موقت جهت جمع‌آوری خون و تخصیص اهداکنندگان خون به این مکان‌ها ارائه‌شده است. اهداف مدل شامل کمینه کردن بیشترین مقدار کمبود در مراکز خون در بدترین حالت وقوع اختلالات در تسهیلات و نیز کمینه کردن مجموع هزینه‌ها در بدترین حالت وقوع اختلالات در تسهیلات می‌باشد. جهت نشان دادن کاربردپذیری مدل پیشنهادی، مساله با روش محدودیت اپسیلون بر روی مثال عددی حل و تجزیه‌وتحلیل شده است

چکیده [English]

In time of natural and man-made disasters, the supply of some commodities which are directly related to human life are very critical. In the real-world, supply systems are exposed to various disruptions in their facilities and these disruptions can essentially affect systems performance and can lead to shortage in the supply and importance of this subject is much more expressed in the blood supply case. In this paper, a multi–objective mathematical model is proposed for the collection of temporary blood facilities and allocation of blood donators to these places. The goals of the model are to minimize the maximum blood shortage in the blood bank and also to minimize the total cost in the worst case scenario in disruptions. In order to demonstrate the applicability of the proposed model, the epsilon constraint method is solved and analyzed on numerical examples.
