| Popis: | 87 Case-base Reasoning is a sort of Expert system developed in recently years. It stores cases in case-base database, and searches the cases in ferms of the similarity among them. It provides the aid whenever new questions or cases come up. It''s very important that how knowledge engineer used expert knowledge. There are a couple of ways used by knowledge engineer to abstract the expert knowledge. The knowledge which is abstracted by a single expert seems to be too subjective. Therefore, more than one expert be comes a beasible way, however, to do this, the integration of experts knowledge become another issues needed to be dealed with. This study is focused on two issues: one is the integration of expert knowledge by using fuzzy theory and the other is the comparision among the cases using the similarity and the linguistic variables. The results of this study reveal that (1) the system which is set up by two experts is more objective than that of only one expert; (2) the fuzzy synthesizing judgement is able to the expert knowledge appropriately; (3) the results turn out to be more usable when we use the similarity rule and the linguistic search similaritiously. |
