Abstract: An information processing device is configured to acquire first data related to a driving operation performed in a first vehicle and second data related to a surrounding condition of the first vehicle, and perform driving evaluation for the first vehicle based on the first data and the second data.

Abstract: A deterioration diagnosis method, wherein the amount of weight loss of a metallic material due to corrosion in atmospheric air for the exposure days is formulated as a function for environmental assessment points which represents a level of a harmfulness of the atmospheric conditions; and the life span of the metallic material is diagnosed based on the corrosion loss calculated from the function.

Abstract: In a method of degradation diagnosis according to the present invention, an equipment degradation diagnosis request is input through network 4 from a diagnosis requester and a degradation diagnosis requests handler is selected in accordance with execution condition information of degradation diagnosis specified in respect of at least one degradation diagnosis requests handler and condition information in accordance with which an diagnosis requester requests degradation diagnosis. A request for execution of degradation diagnosis is made to this selected degradation diagnosis requests handler and the results of execution of the degradation diagnosis obtained by the selected degradation diagnosis requests handler are acquired and output through network 4 to the diagnosis requester. In this way, a service can be implemented whereby diagnosis of degradation requested by a diagnosis requester from a diagnostic service provider is performed rapidly and easily at low cost.
