Unconventional Emergency System Characteristics and Emergency Decision-making Analysis

Compared with conventional emergency, unconventional emergency has typical unconventional characteristics and its system characteristics and emergency decision-making processes and methods are also very special. In order to making a deeper understanding the system characteristics and emergency decision-making mechanism of unconventional emergency, based on the definition and features analysis, the principle of entropy and dissipative structure theory to explain unconventional emergency system status characteristics, this paper analysis of unconventional emergencies and emergency management in the process of entropy state changes; further analysis temporal frame of unconventional emergency decision-making. Analysis shows that the unconventional emergencies happened and management is an Open dissipative system. System entropy changing by increased entropy factors ZS, negative entropy factor FS and system bearing capacity C combined action. Corresponding unconventional emergency system in the process of incubation period, initiation period, outbreak period, evolution period or recovery period and disappeared period, emergency decision-making work of temporal framework can be divided into warning precaution, crisis identification and isolation, integrated response and disposal measures four links.
