document: Diversified SCM standard for the Japanese retail industry In this paper , we present the concept of a diversified SCM ( supply chain management ) standard and distributed hub architecture which were used in B2B experiments for the Japanese retail industry . The conventional concept of B2B standards develops a single ideal set of business transactions to be supported . In contrast , our concept allows a wide range of diverse business transaction patterns necessary for industry supply chains . An industry develops a standard SCM model that partitions the whole supply chain into several transaction segments , each of which provides alternative business transaction patterns . For B2B collaboration , companies must agree on a collaboration configuration , which chooses the transaction alternatives from each segment . To support the development of a B2B system that executes an agreed collaboration , we introduce an SOA ( service oriented architecture ) based pattern called a distributed hub architecture . As a hub of B2B collaboration , it includes a complete set of services that can process every possible business transaction included in a standard SCM model . However , it does not function as a centralized service that coordinates participants . Instead , it is deployed on every participant and executes the assigned part of the supply chain collaboratively with other distributed hubs . Based on this concept , we analyzed actual business transactions in the Japanese retail industry and developed a standard SCM model , which represents more than a thousand possible transaction patterns . Based on the model , we developed an experimental system for the Japanese retail industry . The demonstration experiment involved major players in the industry including one of the largest general merchandise stores , one of the largest wholesalers , and major manufacturers in Japan .
