Abstract: Processing circuitry of a program rewriting device is configured to create a transfer queue for each bus by grouping update data for each electronic control unit, assign threads to transfer queues one by one, starting with a transfer queue with a relatively large transfer data amount, perform parallel transfer of the update data of the transfer queues to the gateway device by using the assigned threads, each time transfer of a piece of the update data is completed, select a transfer queue having a largest transfer data amount from among the transfer queue in which the transfer of the update data is completed and transfer queues to which the threads have not been assigned and in which transfer of the update data is suspended, and continue the parallel transfer by assigning, to the selected transfer queue, the thread assigned to the transfer queue for which the transfer has been completed.

Abstract: A facility working apparatus includes objects (1), a management apparatus (2), and an exterior information source (3) such as a weather company, a power company or the like. Each object (1) and the management apparatus (2), the exterior information source (3) and the management apparatus (2) are connected via a network. Each object (1) includes a facility (1a) such as a heat storage air conditioner, power storage air conditioner or the like, and a controlling apparatus (1b) for working and controlling the facility (1a) and for extracting facility information of the facility (1a) and user determination information. The management apparatus (2) includes a database (2a) and a data processing section (2b). The data processing section (2b) in the management apparatus (2) carries out processing based upon facility information, user determination data, and exterior information, and generates working and controlling information. The information is transferred to corresponding controlling apparatus (1b).
