Abstract:In view of the shortcomings of the grey target decision method when the attribute value is the general grey number, the grey target decision method of general grey number is proposed. Firstly, the concept of interval grey number is further expanded by defining the general grey number. Secondly, the Husdorff distance measure, algorithm and its properties are proposed based on the concept of norm. The concept of the bull's-eye and the bull's-eye-distance of the scheme is defined. The sorting method of grey target decision model based on the bidirectional projection consistency coefficient of positive and negative bull's-eye is constructed. The model solves the problem of decision scheme with more uncertain factors. Finally, the feasibility and superiority of this method are verified by an example. © 2019, Editorial Board of Journal of Systems Engineering Society of China. All right reserved.
