摘要： A component life prediction system 1 includes a server device 10 configured to be able to communicate with a work machine 2, and capable of predicting the life of a component of the work machine 2. The server device 10 acquires operation information of the work machine 2 including information about the operation location of the work machine 2, and a pre-stored aerial photo of the operation location of the work machine 2; estimates the industry in which the work machine 2 is used based on the acquired operation information of the work machine 2 and aerial photo of the operation location; and predicts the life of the component of the work machine 2, based on the estimated industry.

摘要： There is provided a server that includes: an inspection item/main part correspondence table in which inspection items of the work machine and main parts of the work machine are associated; an inspection item list acquisition unit acquiring an inspection item list of the inspection target machine based on information about the inspection target machine received from the terminal; and a main part list acquisition unit acquiring a main part list in which the service parts are enumerated, being associated with the inspection items of the inspection target machine, based on the inspection item/main part correspondence table. The main part list acquisition unit transmits the acquired main part list to the terminal via the communication circuit as the selection information about the service parts.
