چکیده

چکیده
امروزه استفاده از نظریه بازی‌ها در زمینه مدیریت زنجیره تأمین بسیار مرسوم است. از نظریه بازی‌ها نه تنها در قیمت‌گذاری کالاها در زنجیره تأمین، بلکه در مباحث مربوط به تبلیغات و بررسی تعامل اعضای زنجیره تأمین استفاده می‌شود. در این مقاله رقابت بین دو زنجیره تامین که هر زنجیره شامل یک تولید کننده و توزیع کننده است در نظر گرفته می شود. تقاضای اجناس تابعی از قیمت و زمان تدارک است. رقابت تحت سناریو بازی بدون همکاری و با همکاری در نظرگرفته می‌شود. سه نوع سناریو تحت بازی بدون همکاری(نش - استکلبرگ) و با همکاری مختلف برای تجزیه و تحلیل و تصمیم گیری مربوط به قیمت، زمان تدارک و اندازه محموله ساخته شده است. وجود یک تعادل منحصر به فرد در همه بازی ها نشان داده می‌شود و فرمول های دقیقی را برای محاسبه تصمیمات بهینه هر یک از زنجیره ها ارائه شده است. مثال عددی و تحلیل نتایج بینش مدیریتی مفید برای انتخاب بهترین استراتژی ها برای زنجیره ها در محیط های مختلف بازار و عملیاتی را فراهم می‌آورد.

چکیده [English]

Abstract
Today, the use of game theory in supply chain management is very common. Game theory is used not only in pricing goods in the supply chain, but also in advertising discussions and examining the interaction of supply chain members. In this paper, the competition between two supply chains, each of which includes a manufacturer and a distributor, is considered. Demand for goods is a function of price and lead time. Competition under the game scenario is considered nonecooperation and with cooperation. Three types of scenarios have been developed under the game theory none cooperation (Nash-Stackelberg) and with different for analysis and decision-making related to price, lead time and shipping size. A unique equilibrium is shown in all games and detailed formulas are provided to calculate the optimal decisions of each chain. Numerical examples and analysis of the results of useful management insight to select the best strategies for chains in different market and operational environments.
