Multidimensional Sparse Fuzzy Reasoning Method Based on Weight of Precedence Chart

Most interpolative reasoning methods in multi-dimension cannot guarantee the convexity and normality of result,and cannot consider weights of each variable influencing conclusion.This paper proposes a fuzzy multidimensional reasoning method based on weight of Precedence Chart(PC),which confirms the weights by Precedence Chart(PC).Experimental results show that it not only reduces the errors,but also keeps the convexity and normality of the reasoning consequence.
