摘要： 在稀疏规则库条件下，多数的多维稀疏规则条件近似推理方法都难以保证推理结果的凸性和正规性，且没有考虑到多维变量对结论的影响权值。提出一种基于优序图加权的多维模糊推理方法，运用优序图确定权值，实验结果表明，该方法不仅减小推理结果的误差，而且能较好地保证推理结果的凸性和正规性。

Abstract: 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.

Key words: multidimensional sparse fuzzy reasoning, Precedence Chart(PC), weight, similarity
