چکیده
مکانیابی با درنظرگرفتن موضوع رقابت در بازار، یک تصمیم راهبردی و بلندمدت محسوب میشود. چنانچه انتخاب مکان، بررسیهای لازم صورت نگیرد، حیات سازمان تحت تأثیر قرار میگیرد. بهدلیل وجود پیچیدگیهای موجود مسائل مکانیابی، ارائه مدلهای محدودیتهای متنوعی مواجه است. هدف این پژوهش، توسعه مدل رقابتی درنظرگرفتن دو محصول از سوی سه رقیب است؛ برای منظور، مسئله بهصورت بازی مکان ـ قیمت تعریف استفاده ریاضی دوسطحی، مدلسازی شده سطح نخست، بهینه تعیین دوم نتایج تعادل نش، تعادلی بهدست آمد. رفتار مشتری احتمالی نظر گرفته کمک تابع نمایی مدلسازی شد. بهدلیل NP- hard بودن حل الگوریتم فراابتکاری جستوجوی ممنوع، روش انتخابی پژوهش حاضر نشان داد شرایطی که پیش ورود به بیش حضور داشته باشد، مقایسه حالتی بازار انحصاری است، شدت اهمیت بیشتری دارد.

متن کاملa bi-level competitive facility location model considering the reaction of competitors in the market, using the concept of compromise
a facility location is said to be competitive when other facilities are present in the market and new facilities have to compete with these existing facilities for a market share. in other words, in a competitive facility location problem we do not see monopoly that exists in classic location models. in such a situation, existing facilities react to locate new facilities by adjusting their attr...
