摘要
本文在不精确推理的Ｐｒｏｓｐｅｃｔｏｒ模型的基础上，利用其充分性和必要性量度，结合ＭＹＣＩＮ模型中的确定因子，将先验概率转换成较容易给出参量形式。在此基础上，给出一种模糊关系的数据模型，并定义了模糊集合的并、交、差和笛卡尔积等运算，从而对非精确数据及知识描述中的不确定性进行有效地处理。
This paper takes advantage of the inaccurate reasoning model the PROSPECTERS model,uses its measurement on the sufficiency and neccessity,combines the accurate factor in MYCIN model,converts the transcendental probability to parameter forms,which are relatively easy to obtain.Besides,this paper defines the operations of AND,OR,SUBSTRACT and D Multiply on the fuzzy set.So people can suffienciently deal with the uncertainty in the description of inaccurate data and knowledge.
