Abstract:

Developing a dynamic simulation system of unconventional emergency evolution analysis is of great significance for unconventional emergency management. To cover the shortage of existing simulation methods and systems which are used in unconventional emergency evolution analysis, especially their deficiency in integrating the theories, methods and technology achievements within multidisciplinary and multifield, a framework of unconventional emergency simulation system is proposed based on knowledge unit， and with the fusional computation of data, knowledge and model as the core of the framework. Then the implementation of every subsystem is discussed. In this system, the internal relationships among data, knowledge and model are achieved by the knowledge unit. And through the reasoning of the knowledge unit network, the fusional computation of data, knowledge and model within various disciplines and fields are realized. Then the simulation of unconventional emergency evolution analysis is further achieved. Finally, a prototype of the system is put forward. And the process of management and running of the prototype are illustrated through an example of debris flow disaster.
