Products lifecycle management system using radio frequency identification technology

Hitachi Ltd. has been conducting research, development and experiments on a product lifecycle management system using radiofrequency identification (RF-ID) tags, based on next-generation identification technology, in order to correctly collect and process used products. This system makes it possible to collect and process used products efficiently and to correctly monitor the product status, from collection to processing.

Preliminary evaluation of business to business electronic commerce by using qualitative simulation and scenario generation

A scenario generator for qualitative simulation systems has been developed for explaining the influence flow to the concerned node in the structural model. The paper presents the method through which companies evaluate business to business electronic commerce (e-commerce) systems by using the scenario generator. The method consists of the following processes: the adjustment of the structural model to specific companies; the qualitative simulation and the scenario generation of the new systems; and the evaluation of the scenario. This method will be useful for companies to evaluate e-commerce systems.
