Abstract
When a piece of failure occurs, the associated-portion state data items of a relevant equipment and the relevant recovery sequence operated by an operator are recorded as a set of data. At this time, the associated-portion state data items which fall within a plurality of sets of data and which correspond to the same recovery sequence are grouped as the same recovery sequence group. Simultaneously, the common elements to the associated-portion state data items which fall within each recovery sequence group are extracted and recorded as the elements paired with the corresponding recovery sequence. Thereby, when a new piece of failure occurs, relevant associated-portion state data items are compared with the common elements. Then, regarding the associated-portion state data item which coincides with the common element, the corresponding recovery sequence is outputted to teach it to the operator as an available recovery sequence. The failure state data items recoverable with the use of the same recovery sequence are learned by the system per se while analysis is being sequentially performed on the common elements, thereby producing accurate teach sequences with respect to a large numb…
