Abstract
To reconsider the current mass production paradigm and to make products have more added values largely from knowledge and service contents to compensate volume reduction under the concept of dematerialization, we need new engineering methods to look at services, rather than just functions, called "Service Engineering." In Service Engineering, it is desired to fully satisfy receiver's value. This paper aims at proposing a method for forecasting receiver's demand change based on a concept of customer's value importance.
