Abstract
This paper proposes a method for describing product life cycle scenario and a description support system for the life cycle scenario. Our idea is that a designer can determine the life cycle strategy easily by describing the life cycle scenario. We define a representational scheme of the life cycle scenario and developed the support system based on the design rationale. In this paper, we employ Trueth Maintenance System (TMS) to the description support system for the management of alternatives of scenarios. This system enables the user to select the best solution more efficiently.
