Research of enterprise production early-warning management system based on artificial neural network;

On the basis of a civil aviation calamity,which is a complex system, its complexity is probed with the help of the complexity theory's tools (such as chaos, fractal, ANN and so on) and the method of early-warning management, and a primary theoretic frame of complexity research of the civil aviation cala.

In order to handle the problem,it is an effective way to build the early-warning management system of sporadic events of city s traffic.
