The Grey Target Decision-Making for Incomplete Information System Based On The Discrete Grey Number

Based on the grey system theory and approaches, the lower and upper limit set evaluation for discrete grey number is proposed, and on the basis of the grey target decision-making, the approach of grey target decision-making for incomplete information system is studied. First, we discuss how to use the lower and upper limit set evaluation to deal with the evaluation while the evaluation of goals is incomplete, and then we propose absolute and relative off-target distance of the interval grey set, which extends the classical grey target decision-making to the case of discrete grey numbers. Finally, we establish a decision-making algorithm for incomplete information system while the evaluating background is known.
