چکیده

این مطالعه مدل بهینه‌سازی دوهدفه­ای جهت مکان‌یابی مراکز خدمات پزشکی اضطراری ارائه می­دهد که بین توابع هدف پوشش و دسترس­پذیری تعادل برقرار می­نماید. مدل پیشنهادی تصمیمات استراتژیک مکان‌یابی و تصمیمات تاکتیکال تخصیص را درنظر می­گیرد. به‌علاوه این مقاله برخلاف اکثر مدل­ها که ظرفیت ثابتی را برای نقاط بالقوه تسهیلات در نظر می­گیرند که موجب اعمال محدودیت­هایی در کاربرد این مدل­ها می­شود، یک مسئله برنامه‌ریزی پودمانی که قادر به در نظر گرفتن چندین ظرفیت ممکن برای تسهیلات است ارائه می‌دهد. جهت مکان‌یابی بهینه آمبولانس­ها، مدل جدید تخصیص تقاضاهای خارج از محدوده پوشش را نیز در نظر می‌گیرد. کاربرد این مدل بر روی مطالعه موردی که داده­های آن برگرفته از مرکز اورژانس شهر کرمان می­باشد مورد بررسی قرار گرفته شد. درنهایت نتایج عددی به‌دست‌آمده از استقرار مدل و آزمایش­های تحلیل حساسیت به همراه نکات مدیریتی ارائه شده است.

چکیده [English]

The present study introduces a bi-objective optimization model for emergency medical service location to make balance between accessibility and coverage target functions. The recommended model considers location strategic decisions and allocation tactical decisions. Moreover, in contrary to most models which consider fixed capacity for potential points of facilities that cause some limitations in using such models; this article introduces a modular planning problem that is capable of considering several possible capacities for facilities. The new model considers the allocation of demands out of coverage zone for optimal location of ambulances. Applying of this model to the case study that its data obtained from emergency center of Kerman City was studied. Finally, the numerical results obtained from model deployment and sensitivity analysis tests were presented in addition to managerial points.
