چکیده

سیستم سلامت از نظر ماهیتی سلسله‌مراتبی است که وجود پیوند ارتباطی بین سطوح مختلف آن، حل مسئله‌ی مکان‌یابی را برای هریک از سطوح به طور مجزا غیرممکن می‌سازد. هدف این پژوهش، ایجاد یک شبکه‌ی خدمات سلامت سه‌سطحی است. بدین منظور، هریک از مکان‌های داوطلب به عنوان یک واحد تصمیم‌گیرنده در نظر گرفته شده‌اند و کارایی هر یک از مکان‌های داوطلب محاسبه شده است. همچنین یک مدل خطی عدد صحیح مختلط دوهدفه توسعه داده شده که به دنبال کمینه‌سازی زمان جابه‌جایی و بیشینه‌سازی کارایی از طریق انتخاب مکان‌های با کارایی بالاتر است. از روش حدی اصلاح شده برای حل مدل دوهدفه پیشنهادی استفاده شده است. به منظور ارزیابی مدل پیشنهادی یک مطالعه‌ی واقعی روی منطقه‌ی ۱ شهر تهران انجام گرفت. نتایج حل مدل نشان‌دهنده‌ی وجود ناسازگاری بین اهداف است. همچنین

تأثیر پارامتر ارجاع روی جریان بیماران در سیستم به وضوح مشخص است. مقایسه‌ی شبکه‌ی موجود با شبکه‌ی پیشنهادی حاکی از بهبود در وضعیت موجود از نقطه نظر اهداف ارائه شده است.
