In order to reduce the environmental load caused by a mass waste-producing society, it is very important to achieve closed-loop product life cycles. To do so, it is necessary to realize Inverse Manufacturing [1]. However, there is not only physical life but also value life which terminates because of minor functions. We focus on extension of this product value life and propose the design methodology of upgradable products [2]. To do this, we create an upgrade plan. And to make the plan more realistic and flexible, future technological trends and user demand must be predicted. Generally, user demand is assumed to be influenced by technological trends. Based on this assumption, this paper suggests producing a general upgrade plan that considers flows from technological trends to user demands. Furthermore, we also propose the way to correct upgrade plan flexibly to respond to sudden event in the future which is expressed as the change of product components.
