Only a few decades ago, it was cleared that our global ecosystem cannot be assumed as infinity. Thus to seek an answer about a question: "how our society can be robust in a limited space", this preface was introduced, and two paper were invited from young researcher to make a discussion.
In this preface, a consistent rule was sought on four desiderata to discuss about ecological open dissipative system (ODS) management. Then basing on Kitano(1999) 's hypothesis, the trade off among the three systematic characters, such as robustness, resource demands, and performance, and locally another trade off between robustness and fragility were considered. In this order, a simple Boolean algebra from Bayes' theorem was shown to analyze the structural profiling for ODS.
