SCM can be divided into three main activities – purchase, manufacture and transport (Thomas et al., 1996). Cooper et al. (1997) analyzed the three elements of SCM – supply chain business processes, supply chain management components, and supply chain network structure. Figure 4 shows the entire elements in SCM frame. It displays the details of the whole processes from purchasing, management, production, and distribution to customers. The information flow is like an individual system to link the whole supply chain from supplier and manufacturer to consumer. Unimpeded information flow could increase the operation accuracy for costs saving and promote the competitiveness of firms. The product flow proceeds through the whole production processes from material supply via manufactories till providing the finished products to consumers. The items in vertical direction show the various management tasks within the supply chain. Particularly, the return flow, or reverse logistic, is one of the elements in the system but with converse direction from the others.
