Structural description method of the sustainable society scenarios for scenario design

Today, many scenarios are described for envisioning sustainable society such as the IPCC's Emissions Scenarios. These scenarios often employ simulators to provide a basis for their descriptions. However, existing scenarios do not explicitly describe the relationship between scenario document and simulators, e.g. its simulation conditions. This spoils reusability of scenarios. We propose a scenario design methodology to describe sustainable society scenario efficiently and effectively. We are developing Sustainable Society Scenario (3S) Simulator to support scenario design process. This paper proposes a method for making new scenario variants efficiently by reusing existing scenarios and simulators. In order to realize proposed method, we define a structural description method of scenarios for connecting scenarios with their simulators dynamically and we develop a data managing tools as components of 3S Simulator to modify scenarios by using proposed method. In a case study, scenario structure including simulator is clearly represented and we succeeded in describing new sub scenario easily by reusing existing scenario and simulator.
