A measuring method of satisfaction rating in service engineering

We can expand the service time zone and the service offer place at a low price by using the system that mechanizes it. However, user´s complaint about the system is not a little. The service engineering proposes the model that user´s satisfaction rating is fed back to the system. We tried a measurement of the satisfaction rating along the model of the service engineering for a system that constructed by Web. As a result, it was clarified that we can classify users by the distribution of the inspection time of users.
