ABSTRACT
With the progress of technology and the high speed renewing in recent years, the life circle of products are shorter than before. The topic of reverse logistics is gotten more attention among enterprises. Therefore, we need to use recycling materials to reduce the costs of products. The integrated inventory system of supplier and buyer is developed by considering the use of recycling cost variation of parameters. The aim is to minimize the total joint annual costs incurred by the vendor and the buyer. The expected annual integrated total cost function is derived and an analytic solution procedure is proposed to determine the optimal policy. Finally, numerical examples are also given to illustrate the solution procedure presented in this article.
The study examines the product attributes, quality of service, and communication method. The results indicate that the most influential element of selection of television shopping goods to consumers in the decision-making is the product attributes, followed by service quality. Meanwhile，the prior consideration key factors is based on the indexes as following: customer expectations, business reputation, price of goods, accessibility on exchanging or refunding, limited time and goods and ten-days trial period. The most critical indexes are selling scenario and advertising representative.
