Investigation of foundation theory of safety & security complexity

Abstract

With the continuous emergence of complex safety & security (SS) problems, SS complexity studies have become an inevitable tendency of SS science development. First, evolutions of research paths and objects of SS science in the past 100 years and some typical new viewpoints on SS science research in recent years are briefly summarized in order to prove the necessity of SS complexity studies. Also, multi-dimensional analysis of SS problems is made to show the essential reason why SS complexity studies are required. Then, historical analysis method, reasoning method, induction method, theoretical modeling method and prediction method are used to carry out the following research on the basic theory of the SS complexity: typical methods and principles of SS complexity studies are summarized; core concepts and basic definitions of SS complexity are built; some criteria on judging SS complex issues are put forward; models which can be used to express the SS complexity system are constructed and some controlling strategies for the SS complex system are proposed; and finally, the conclusions and outlooks of SS complexity studies are given. These results are of great significance for enrichment of SS science.
