Equipment maintenance method, device and system, electronic equipment and storage medium

The invention discloses an equipment maintenance method, device and system, electronic equipment and a storage medium, and belongs to the technical field of equipment maintenance. The method comprises the following steps: acquiring at least one of equipment operation data, historical maintenance records and yield data of target equipment; inputting at least one of the equipment operation data, the historical maintenance record and the yield data into a failure probability model to obtain failure probability information of the target equipment output by the failure probability model; inputting the failure probability information into a residual life prediction model to obtain residual life information of the target equipment output by the residual life prediction model; and performing cost analysis based on the failure probability information and the residual life information, and determining an equipment maintenance strategy of the target equipment. According to the method, the residual life and the failure p
