******** Abstract:
The uncertainty problem of the test system BC-3190 origins from the
insufficiency of diagnostic information. In this paper, the technology
of Acceptance Threshold is employed to prevent the database from
inflating unreasonably. Meanwhile the conventional algorithm of the
certainty factor of the rule antecedent is revised so that the Key
Conditions are guaranteed to propagate in the forward-chain reasoning.
As a result, the uncertainty problem of the knowledge and evidence can
be solved to a considerable degree.
