ADVANCES IN SUSTAINABLE SECURITY SYSTEMS ENGINEERING WITH DRAMA THEORY (DT) Ⅱ

We put forth Drama Theory Ⅱ (DT Ⅱ) as a formal multiple participant decision making framework that can be used to systematically model complex security challenges,and advance the field of Sustainable Security Systems Engineering.DT Ⅱ is defined as a theory of "large world" pre-game communication and equilibrium selection.While game theoretic tools have been widely applied to resolve environmental conflicts and promote global security,traditional game theory assumes that decision makers,options,and preferences are fixed.A mathematical treatment of key drama theoretic concepts (i.e.positions,intentions,doubts and dilemmas) is provided.The dynamics of the drama theoretic process are discussed and the expected equilibrium set is derived.The fundamental theorem of drama theory is proven and all theoretical results are applied to promote sustainable security solutions.It is emphasized that DT Ⅱ represents a flexible systems engineering technique to address time-sensitive,multi-faceted,and complex multiple participant negotiations.
