First, in this method, the interval number linear transformation operator is used for normalized processing of the original decision-making information and the interval number positive and negative clouts of grey target intervals are designed; second, in full consideration of the spatial projection distance between each plan and the positive and negative clouts, the off-target distance is taken as the basis for the spatial analysis of vector and a new comprehensive off-target distance is obtained; then, with the criterion of minimum comprehensive off-target distance as the objective, a target planning model is constructed to calculate the attribute weight and finally the sequencing of the plan is determined. Finally, the feasibility and effectiveness of the grey target decision making model is verified through an example.]]>Mundaca, L. and L. Neij,2009Willems, P.,2009Ho, W., X. Xu and P.K.
