New decision model of grey target with both the positive clout and the negative clout

This paper studies on the decision model of grey target, and defines the ideal optimization scheme is the positive clout and the ideal inferior scheme is the positive clout of the grey target. This paper comprehensively considers the optimization and the positive off-target distance, and base on the spatial analysis, defines the comprehensive off-target distance. Base on the size of the comprehensive off-target distance and the uncertainties of the index weights, this paper established a model of goal programming, and the gets the index weights by solving the model. Then the decision model of grey target with both the positive clout and the negative clout is established. Finally, the method is proved feasibly and effective through an example.
