隨著消費者環境意識的增加，在政府法規的要求下，企業紛紛加入綠色供應鏈管理的行列。透過系統化的綠色管理方式，使企業更具競爭力。除此之外，提供售後服務給消費者也是製造商常用來增加其競爭力的策略。許多文獻已分別討論服務與綠色意識對供應鏈的影響，但尚未對該策略的互動進行討論與分析。本研究考慮的通路模型是由兩位製造商與一位零售商所組成。假設第一位製造商擁有製造新品的能力，第二位製造商有製造再製品的能力。兩位製造商銷售產品至零售商，並提供服務給消費者。消費者會依據價格、服務以及產品的綠色程度來購買產品。因此，本研究以Stackelberg賽局模型描述製造商與零售商的決策順序；並以最大化製造商與零售商各自利潤為目標，找出成員的最佳定價策略，並探討最佳解的存在與唯一性。此外，我們考慮了顧客隨機性需求，並加入因隨機性需求而產生的缺貨成本與殘餘價值，以更符合實際情形。最後，以數值例子說明如何應用此模型，其結果如下：一、製造商可透過提升其服務或綠色水準，使其利潤增加。二、消費者綠色意識越高，製造商利潤不一定會跟著提高。三、在需求不確定下，製造商針對不同情境採取不同的製造策略，使其利潤最大化。

Due to the public environmental awareness arising and legislative requirements, firms are forced to adopt sustainable supply chain management. Green supply chain management (GSCM) is emerged as a systematic solution for firms to maintain competiveness. Besides, service-providing is another strategy which is commonly adopt by manufacturers to improve their competitiveness. Numerous researches have investigated the effects of service and consumer environmental awareness on supply chains, while few studies have discussed the intersections between service and consumer environmental awareness. A supply chain consisting of two manufacturers and a retailer is considered in this thesis. Assume that the first manufacturer is an original equipment manufacturer (OEM) that produces new product, while the second manufacturer is the remanufacturer producing refurbished products. Both manufacturers sell products to a common retailer and provide service to their end consumers. Consumer demand is influenced by three factors: (1) retail price, (2) service and (3) the efforts of eco-friendly operations. Hence, we provide a Stackelberg game model which is used to represent the decision-making of manufacturers and the retailer. The objective is to find optimal pricing policies to maximize their profits of all members in this supply chain. We also derive the corresponding existence and uniqueness conditions for equilibrium solutions. Furthermore, we extend the proposed model and take the consumer stochastic demand as well as the costs of goods shortage and salvage value of unsold products into account. Finally, numerical examples are provided and demonstrate the results as follows: (1) manufacturers can improve their profit by increasing the service level or eco-friendly level; (2) manufacturers’ profit may not increase with the consumer green awareness; and (3) manufacturers should adopt different production strategies under different situation to maximize their own profit when facing demand uncertainty.
