Model Design And Analog Modulation Of Emergent Earthquake Rescue System Based On CAS Theory

Earthquake disaster is one of nature disastrous phenomena that does harm to national public security, which is more destructive and disastrous than floods and hurricane with its accidental outburst, disastrous, social and lasting features. The earthquakes in China have some features of high frequency, high intensity, broad distribution, shallow epicenter, and high destruction. Emergent earthquake rescue is one of the keys to reduce human loss, which can prevent the disaster from developing. Many cases of emergent earthquake rescues in domestic and aboard showed that, the first task after destructive earthquake is to develop a timely, effective and efficient, orderly life rescue to reduce death rate. According to related sources, 72 hours after earthquakes is the golden time for rescue. Hence, the research on theories and methods of on-the-spot quake rescue should be paid a high attention, especially under the circumstance of continuous aftershock, frequent subsequent disasters and chaotic social situation. Therefore, it is essential and urgent to coordinate on-the-spot rescuer and self-saving personnel to enhance the efficiency and save more people in danger.Now, the research of emergent earthquake rescue focuses mainly on problems of top-level management and emergent scheme, which took system design and organizational planning into consideration. Some technical research of emergent earthquake rescue focuses on professional rescue techniques and route selection and so on. It is very rare to combine complex scientific theories, especially CAS with emergent earthquake rescue, and to make analog simulation on complex emergent earthquake rescue system. Thus, the paper analyzed the complex adaptation of the earthquake rescue system from four features—aggregation, nonlinearity, flow, and diversity, and from three systems—tagging, internal model, and building block, and explained that the earthquake rescue system is a kind of complex adaptation system. As to defining the rescuing subjects, the rescued subjects, and the environments, the paper found the evolving rules and behaving rules of the rescuing rules, and mutual rules of the subjects and the environments, and constructed basic model of complex adaptation system of earthquake emergent rescue. The paper made an analog emulation based on Swarm, and performed a case study comparing the emulation results with practical rescue condition in Wenchuan earthquake, which is initiative to some extent.
