چکیده مقاله :
در این مقاله، از مقادير فازي در روش فرا-ابتکاري براي مکانيابي محل تاسيسات ترمینال استفاده مي¬شود. این مقاله بر اساس یک روش مدرن الهام گرفته از طبیعت به نام الگوریتم نهنگ (Whale Algorithm) نوشته شده است وبا مسائل بهینه سازی علمی و مسائل مدل سازی آزمایش شده است. برای ارزیابی عملکرد روش پیشنهادی، ضرايب فازی برای حل مسئله تخصيص مکان، اعمال شده است، به نحوي که فرضیه‌های مسئله، متغیرهای تصادفی فازی و ظرفیت هر مرکز نامحدود درنظرگرفته شده است. طبق نتایج این پژوهش، مسئله مکانیابی جایگاههای ترمینال بطور عملی حل میشود و در دنیای واقعی مکان بهینه این تاسیسات پیشنهاد میگردد همچنین نتایج بهینه سازی عددی نشان می دهد که روش پیشنهادی عملکرد بهتری نسبت به روش های مشابه دارد
In this article, fuzzy values are used in the meta-heuristic method to locate the location of the terminal facility. This article is written based on a modern method inspired by nature called Whale Algorithm and it is tested on scientific optimization problems and modeling problems. To evaluate the performance of the proposed method, fuzzy coefficients have been applied to solve the location allocation problem, in such a way that the hypotheses of the problem, fuzzy random variables and the capacity of each center are considered unlimited. According to the results of this research, the problem of locating the terminal locations is practically solved and the optimal location of these facilities is proposed in the real world. Also, the numerical optimization results show that the proposed method has a better performance than similar methods
