Abstract: A model sharing system includes: a plurality of control apparatuses that each control a corresponding one of apparatuses to be controlled; and a model management apparatus that stores a learned model correspondingly to an operating status of the apparatus to be controlled. The control apparatus-obtains, from the model management apparatus, a learned model corresponding to an operating status identical to or similar to the operating status of a corresponding one of the apparatuses to be controlled and then controls the corresponding apparatus using the obtained learned model. The operating status includes at least one of the following: type of the apparatus to be controlled; an environment where the apparatus to be controlled is installed; or setting content of the apparatus to be controlled.

Abstract: An air-conditioning management apparatus for managing an air-conditioning apparatus having an indoor unit for air-conditioning an air-conditioning target space is provided. The air-conditioning management apparatus includes a schedule information acquisition unit that acquires data of schedule information sent from a schedule management system having a schedule for a facility in which the air-conditioning apparatus is installed; a human detection information acquisition unit that acquires human detection information data related to detection of a human detection sensor, the human detection sensor being configured to detect presence or absence of a human in the air-conditioning target space in which the indoor unit is located; and a learning unit that performs a learning process to associate contents of the schedule with the indoor unit corresponding to the human detection sensor based on the data of schedule information and the human detection information data.

Abstract: The influence extraction device includes an output result acquisition unit, a change extraction unit and a search unit. The output result acquisition unit acquires a first output result of a subsystem before a change in a program, and a second output result of the subsystem after the change in the program. The change extraction unit compares the first output result and the second output result, and extracts an interface item whose item value is changed from a plurality of interface items that the subsystem includes. The search unit searches subsystem information for another subsystem including an interface item related to the interface item extracted.
