Lifetime prediction system

Abstract

An objective is to provide a lifetime prediction system that allows a highly reliable lifetime prediction even when record of events having occurred in products are inaccurate. A lifetime prediction system 1 includes a server device 5 that predicts a lifetime of a product as a machine such as a work machine 2 or a machine part. The server device 5 includes an operation information database 52 that stores operation information for each of a plurality of products, a history information database 53 that stores history information indicating a history of event data as a record of an event having occurred in each of the plurality of products and an arithmetic processing device 54 that predicts the lifetime of the product. The arithmetic processing device 54 calculates an event data acquisition rate indicating a rate of product having the event data in which occurrence of the event is accurately recorded to the plurality of products, based on the operation information and history information, and predicts a corrected lifetime of the product based on the calculated event data acquisition rate.
