The processing to do this is performed. At this time, the data learned by the data learning module 133 is preferably implemented not only to serve as a source for executing the scheduling, but also to serve as a source of operation processing by the scheduling. For example, when a load such as a motor is deteriorated after a lapse of time, the data learning module 133 recognizes the deterioration of the motor through learning based on log data, and automatically adjusts the operation setting value of the motor accordingly. By changing to, multitasking can be realized so that the motor can be operated adaptively to load reduction.
