Abstract
This research is aimed to estimate the present situation of introduction of information and telecommunication technology by Japanese major steel companies and make clear its more useful ways in the future with the analytic hierarchy process called AHP method. Furthermore, we made the similar survey on a chemical company and several governmental institutes to compare with the results on the steel companies. As far as our investigation is concerned, the steel companies have been found to be yet fairly behind the said other organizations compared in terms of introduction of the information and telecommunication technology into their business activities and have more possible areas to be targeted upon to improve their business efficiency.
