The production asset monitoring system has at least one control unit arranged to associate a respective state machine which each asset in the one or more production assets. Each state machine implements a plurality of operating states, out of which operating states at least one state can be categorized as a productive state and at least one state can be categorized as an unproductive state. The production asset monitoring system also has a sensor system configured to detect a current operating state for each state machine. The control unit is configured to aggregate the states of a plurality of assets into a report indicative of production asset utilization. ## Claims ### Claim 1 A production asset monitoring system,
