Proposal of sustainable society scenario simulator

Although the life cycle engineering aims at ‘sustainability’, its image is still unclear. While various scenarios have been proposed for this purpose, their rationality and assumptions are not clearly described because they are just documents referring some simulation results. For analyzing and composing the scenarios, this paper proposes the framework of ‘Sustainable Society Scenario (3S) Simulator’ and a methodology for structural representation of scenarios. This paper also demonstrates a prototype system and its structural representation of the IPCC scenario. The representation clarified the basic structure of this scenario and highlighted a set of assumptions as the base of this scenario.
