Development of System Core Theory and its Application in Real Estate System of Wuhan
The theory of system core is given a method to determine key elements of the system based on graph theory, but it is difficult to apply in practice for the question of how to change a system to a graph and multi-core in a system, this paper give a method to change a system to a graph based on correlation analysis, and give a modle to select system core based on cluster analysis, More, in the case of the real estate system of Wuhan, a diffusion index curve is given based on the elements of system core selected by the model, the result illustrates that Wuhan real estate arises in 1991 and to its peak in 1993, and then declines to the bottom in 1996; next, it fluctuates in a small range and becomes smooth since 1999, but a slight upward trend during 2000, this conclusion is consistent with the actual development status of the real estate in Wuhan and prove the validity of the model.
