Several methods for approximative diagnostic problem solving under uncertainty have been adopted for expert systems (ES). Usually, however, no difference is made in application of those methods in controlling activation of diagnostic concepts for evaluation and in concept evaluation itself. Two different and independent control flows of approximative inference have been incorporated in our diagnostic expert system CODEX [l,3] Their principles are introduced briefly in our contribution.
