ファジィ数間の距離を応用したファジィ推論(<一般講演>ファジィ理論,医療情報システムにおけるソフトコンピューティグ)

抄録

In this paper, a new fuzzy reasoning method is proposed based on the distance between fuzzy numbers. We have used the fuzzy reasoning method "Product-Sum-Gravity Method" for the educational evaluation. The strict monotonicity is the important point for applying fuzzy reasoning to "educational evaluation". However the numerical reasoning function of this method doesn' t always hold the strict monotonicity condition. Then, by defining a distance between fuzzy numbers, we can mathematically introduce a new fuzzy reasoning that could make it clear the above point.
