In the process of developing supply chain logistics strategy, generally require attention to the following questions： To segment customers, we should determine the appropriate level of customer service, such as order cycle, inventory levels and other modes of transport for different types of clients; Group products according to sales on them, we can take different strategies for each category of products. Order entry, order execution and delivery job processing accounted for a large proportion of logistics activities, which requires technology and management to make the entire processes of supply chain logistics more efficient, especially for the interface area between members of enterprises. We can eliminate redundant work by integrating flow, improve logistics efficiency.展开更多
