Abstract

In this paper some improvements on certainty factor model are discussed aiming at: 1) including, in a rule “E→H”, not only theCF ofH whenE exists but alsoCF of\(\bar H\) whenE does not exist (partly or completely). For this purpose another factor\(\bar CF\) is added into the original model; 2) improving the model so that it can tackle problems with unknown evidence. In this aspect two concepts are introduced: (relative) maximum existence risk and (relative) maximum non-existence risk. An important result is that even if some necessary evidence is unknown one can still know the tendency whether the conclusion is true. Based on the improvements a conflict resolution model for problem-level conflict is also presented.
