Abstract
Each organization (e.g., a retailer, a wholesaler, a maker, a material supplier) of the supply chain (SC) performs the generation of the information with information about the stock on demand, ability, and delivery date. Supply chain management (SCM) is carried out using such information. In other words, it is important to build enough information networks between organizations because a successful SCM uses the necessary information. However, there are few quantitative methods to evaluate the adequacy of the information network in SC. We develop a method to evaluate the adequacy of the information network quantitatively to manage SC by the main subject. In that way, we pay attention to the difference in the structure of the information network for the information of each type and divide an information network into some subnetworks based on the type of the information and evaluate each subnetwork and, as a weighting level of each subnetwork, get evaluation index SCV, and the information network is evaluated comprehensively as SCV. Using the evaluation technique, we evaluated a smart system of Ali Baba. Furthermore, we applied the old and new SC information network evaluations of the plastic wire production company which we evaluated before and compared it.
