1. A support device comprising:
a state value acquirer structured to acquire a plurality of state values representing states of a plurality of controlled devices during operation of the plurality of controlled devices;
a predictor structured to estimate predicted values for the plurality of respective state values at a predetermined future time point based on the plurality of respective state values acquired by the state value acquirer;
a notifier structured to, in a case where an index calculated based on a difference between each of the state values at the predetermined time point acquired by the state value acquirer and each of the predicted values at the predetermined time point or a later time point than the predetermined time point estimated by the predictor or a change ratio of the difference satisfies a predetermined condition, provide notification of the case; and
a calculator structured to calculate the index by means of a predetermined index calculation algorithm in which the difference or the change ratio of the difference is weighted respectively based on a magnitude of an influence which the difference or the change ratio of the difference calculated for each of the respective state values has on operation of a specific controlled device,
wherein the index includes a degree of importance indicating a magnitude of an influence on the specific controlled device and a degree of urgency indicating urgency of an influence on the specific controlled device.
