Comments on "FuzzyShell: a large-scale expert system shell using fuzzy logic for uncertainty reasoning" [with reply]

The above paper by Pan et al. (ibid. vol.6 (1998)) presents a rather complicated mechanism allowing fuzzy evidence to be aggregated when fuzzy inferences are made about the same fuzzy variable by different rules. The purpose of this comment is to present a simpler way to address this FuzzyCLIPS problem. In reply, the authors point out that the commenter´s main conclusions about their work are ill founded. They believe that his erroneous conclusions were caused by his misunderstanding the difference between rule firing and evidence aggregation in their work.
