This paper develops a dynamicmodel in a one-supplier-one-retailer fresh agricultural product supply chain that experiences supply disruptions during the planning horizon.The optimal solutions in the centralized and decentralized supply chains are studied. It is found that the retailer’s optimal order quantity and the maximum total supply chain profit in the decentralized supply chain with whole...

I is common for a retailer to sell products from competing manufacturers. How then should the firms manage their contract negotiations? The supply chain coordination literature focuses either on a single manufacturer selling to a single retailer or one manufacturer selling to many (possibly competing) retailers. We find that some key conclusions from those market structures do not apply in our ...

the concept of coordination in supply chain management is different from the viewpoint of the roles of this chain and this difference causes more uncoordination at the entire of the supply chain. hence, regarding to the importance of this subject at the performance of supply chain, the clarification of the coordination concept as a casual model seems very necessary. in this research, the cognit...

In this paper,a coordination model has been investigated for a two-level supply chain (SC) consisting of one retailer and one supplier under periodic review inventory system. The review period and the retailer’s safety factorare assumed to be decision variables. The retailer faces stochastic demand following a normal distribution with known mean and variance. Moreover, it is assumed that unmet ...

This paper deals with the coordination of supply chain composed of a leading supplier and one retailer as a follower under asymmetric demand information. The demand information asymmetry is portrayed by the state of demand forecast information, accordingly the model, the state of demand information is the special discrete distribution, is established. The parameters menus, which are the optimal...

Abstract: To understand the dynamics of the manufacturer’s effort to reduce pollution in a supply chain consisting of manufacturer, retailer, and consumers, we analyze four cases according to consumer awareness of the pollution’s harmful effect, i.e., environmentally aware versus ignorant, and supply chain coordination, i.e., competitive versus cooperative. Applying differential games, we deriv...

هدف این پژوهش، طراحی مدل بهینه‌سازی دوسطحی برای زنجیره تأمین است؛ به‌طوری‌که تصمیم‌گیری غیرمتمرکز کمّی و کیفی را در سطوح استراتژی تاکتیکی ادغام کند. کارخانه تولیدی نقش تصمیم‌گیرنده سطح بالا با ارائه تخفیف مقداری، به دنبال ترغیب مشتریان سفارش خرید بیشتر است. پایین، به‌عنوان پایین تمایل دارند مقادیر از طریق مشارکتی، مقیاس اقتصادی دست یابند. یکی نخستین پژوهش­هایی است که یافتن راه‌حل‌های بهینه مسئله...
