一种新的基于区间估计的不确定推理模型

A NEW INTERVAL-BASED UNCERTAIN REASONING MODEL

建立了一种新的基于区间估计的不确定推理模型，它继承了ＳＬＰ的模型和ＭＹＣＩＮ的模型的优点，即既能很好地区分证据的出现是导致对假设的信任或是怀疑，又能表示“不知道”的信息。并且，还能与点估计的ＭＹＣＩＮ模型兼容。最后给出了一个兼容点估计和区间估计的例子，说明了本文所建立模型的能力．

A new interval-based uncertain reasoning model is constructed here, which inherits the advatagesof SLP's and MYCIN's, and improves them. Moreover, MYCIN's model based on point-estimate is itselfa special case, so the interval-estimate and point-estimate can be coexistence in a system. Fmally, anexample is given to illustrate the power of our model.
