Abstract
Life cycle design requires planning of a product life cycle in addition to designing of a product itself. One of the effective methods to plan the product life cycle is by describing of a life cycle scenario, which should be then realized by designing the product and its processes. On the other hand, the life cycle scenario should be decided by keeping the consistency of the product's functionality and performance. This paper proposes an integrated design environment to support the life cycle design comprehensively. In other words, we propose a design system that supports a designer to describe the life cycle scenario and to design product in an integrated manner.
