Abstract:
There is provided an equipment element maintenance analysis system including: a history information acquirer that is attached with at least one equipment element and acquires, at a predetermined timing, operation history information on a piece of manufacturing equipment for manufacturing a product; an error rate calculator that calculates an error rate based on the number of errors related to each of the at least one equipment element, included in the operation history information; a maintenance determiner that determines maintenance necessity of each of the at least one equipment element; and a notifier that notifies an information item on an equipment element determined to require maintenance among the at least one equipment. The error rate calculator calculates, as a latest error rate, an error rate in a latest predetermined period from the acquired operation history information, the maintenance determiner determines an equipment element with the latest error rate greater than or equal to a predetermined value among one or more equipment elements with a large number of errors as the equipment element that requires maintenance, the one or more equipment elements being included in the at least one equipment element, and the notifier lists the information on the equipment elements with a large number of errors in order, and notifies the number of errors and requirement of maintenance.
