An analysis support system has been developed of various energy and environmental system for the sustainable development. The proposed support system can model, simulate and account the flows of matter, energy and information with tens or hundreds of elementary processes in the target energy and environmental system. It is based on the combination of Multilevel Flow Model (MFM) and Geographic Information System (GIS) and can account various indices for sustainability. The values of the evaluation indices can be utilized to not only test the feasibility of one scenario but also carry out the inter-comparison of various optional scenarios.
