Abstract: Systems and methods described herein relate to an asset risk predictor that may receive data corresponding to one or more industrial assets and generate a device model corresponding to the one or more industrial assets. The device model may indicate a relationship between a normal operation of a first industrial asset and data acquired by a second industrial asset. The device model may be trained while the first industrial asset and the second industrial asset are in situ and operating within a desired industrial automation process. An alert score may be generated based on the relationship indicated by the device model, where the alert score may be an indication of a likelihood of an event occurring at the first industrial asset. A maintenance work order may be generated based on alert scores and existing work orders.
