طراحی مدل رهبری در زنجیره های تامین سه سطحی نامحدود: نظریه بازی های غیرهمکارانه پویا

هدف از مدیریت زنجیره تامین، بهبود فعالیت های مختلف اجزا و سطوح یک زنجیره تامین به منظور بهبود وضع کلی است . در این هنگام ممکن است بین اهداف اجزا و سطوح مختلف در جهت رسیدن به اهداف کلی، تضاد و تناقضات بسیاری مشاهده شود، که این اختلالات و تناقضات به مرور زمان به کاهش قدرت و رقابت پذیری منجر خواهد شد . از جمله تعارضات، هزینه های بازاریابی، قیمت گذاری و موجودی هستند. در تحقیق حاضر و با فرض عدم همکاری بین سطوح گوناگون و در حالت بازی های پویا با اطلاعات کامل، شناسایی رهبر مناسب از بین سطوح مختلف، مورد نظر است . در حالت بازی غیرهمکارانه پویا، هر یک از سطوح، اعم از خرده فروشان، تامین کنندگان و تولیدکنندگان، بسته به قدرت چانه زنی و جایگاه خود در بازار، می توانند نقش پیشرو را داشته باشند . با بررسی مدل های گوناگون، نتیجه گیری شد که حرکت رهبری از انتهای زنجیره به ابتدا، سود کلی زنجیره تامین را کاهش داده است.

Designing Leadership models in a Three Level Unlimited Supply Chain: NonCooperative Game Theory Approach

The role and importance of supply chain management, has faced with many challenges and problems. Although a comprehensive model of supply chain issues, has not been explained, we have to indicate that issues such as reviewing the theoretical foundations of information systems, marketing, financial management, logistical and organizational relations have been considered by many researchers. The objective of supply chain management is to improve various activities and components to increase overall supply chain system benefits. In order to achieve the overall objectives, many contradictions may occur between the components and different levels of supply chain and the contradictions that these disorders over time, result in decreased strength and competitiveness of the supply chain. Such conflicts, like marketing costs (advertising), pricing and inventory can occur during the supply chain life cycle. A Game Theory approach with respect to property is the appropriate tool for collaboration in the supply chain. This tool is used for collaborative making in any kind of supply chain such as cooperative supply chain and noncooperative supply chain. In the present study and assuming a lack of cooperation between different levels of a supply chain, a dynamic game with complete information has been generated. In addition identifying appropriate leaders of various levels of the supply chain is considered. NonCooperative dynamic game mode (Stackelberg Game), for each of the three levels of supply chain including retailers, suppliers and manufacturers are modeled. Depending on the bargaining power and its position in the market, any level of supply chain can make a leader of the following rule. In the present study, the equilibrium model to play Stackelberg game may be led by a leader or leading players and ultimately identifying and modeling the appropriate unlimited three level supply chain are determined.
