Exploration in Complex Systems for Environmentally Symbiotic and Sustainable Society

The authors assume that it is necessary to find a set of solutions to the crucial issues concerning the relation between the global environment and the sustainable human society. Based on the assumption, the authors have been developing man-environment-society system models to simulate the characteristic phenomena related to the issue. This paper describes one of the models focusing on a social dilemma that actions rationally performed to make individual’s indoor thermal environment better bring about worse environment against the rational decision. Some results of the case study simulations with the purpose to find some crews to deal with the issues are also shown.
