再制造/制造集成系统中的制造商-零售商协调决策问题

Coordination & decision-making between manufacturers and retailers in integrated remanufacturing & manufacturing system

提出了由1个制造商、2个零售商组成的双层再制造/制造集成物流网络模型。零售商负责产品的销售与废旧产品的回收。在正向物流中,零售商之间存在数量竞争;在逆向物流中,回收产品的总数量由零售商提供的单位回收价格决定,而各零售商所得回收产品的份额则由零售商提供的单位回收价格与消费者偏好共同决定。利用博弈论,得到了完全信息下的纳什均衡,发现零售商订货量随着制造商的批发价格的增长而递减。在回收中,零售商的单位回收价格不超过制造商提供的单位价格一半。研究了制造商如何协调正向与逆向物流,以便最大化自身的利润,该项研究成果对制造商的决策具有一定指导作用。

A model of remanufacturing/manufacturing logistics network was proposed, which was composed of one manufacturer and two retailers. Within this model, retailers were taking charge of sales and collection of returned items. There were quantity competitions among retailers in the obverse logistics. In the reverse logistics, the total amount of returned items was determined by unit price offered by retailers, while the portions of returned items collected by retailers were decided by both unit prices from retailers and customers＇ preferences. The Nash equilibrium under the complete information was obtained using game theory, which indicated that the total order amount of the retailers decreased with the wholesale price increasing. In reclamation, the retailers＇ unit prices couldn＇t exceed half of the unit price offered by manufacturers. The problem of coordinating obverse logistics and reverse logistics by manufacturers so as to achieve maximal profit was studied. Some management insights for manufacturers were also put forward.
