Research on Grey Relation Analysis Model Based on Projection Pursuit Coupling Model

By using multi-criteria projection pursuit coupling model based on the principle of maximum entropy, multidimensional grey relation analysis values can be integrated into the projection value of single dimension which indicates the advantage of each scheme, so the schemes sample can be optimized according to the projection value of each scheme, the larger it is, the better the scheme is. In order to find out a new method for the application of the projection pursuit coupling technique in the grey relation analysis scheme optimization, real coded accelerating genetic algorithm can be used to optimize the projection pursuit coupling model, to simplify the implementation process of the projection pursuit coupling technique, and to overcome its calculation complexity and the difficulty of its programming implementation.
