<p>PURPOSE:To correctly indicate the degree of ambiguity without extending the period required for diagnostic processing even when the causal relation between an abnormal event and the abnormality cause is ambiguous. CONSTITUTION:Prerequisites for estimating the abnormality cause are shown in the tree structure type from the upper level to the lower level in the first knowledge data 8. The second knowledge data 9 are the matrix type knowledge data, and the item of the corresponding abnormality cause and the level of the correlation between the item and the prerequisites are shown for each prerequisite of the lowest level. When 'unbalanced vibration' occurs during 'constant- speed operation', for example, an abnormality cause estimating means 5 evaluates the correlation on only four items in a block 10, and it estimates one or two or more items of them as abnormality causes.</p> |
