The effect of multi-sensor data on condition-based maintenance policies

Industry 4.0 promises reductions in maintenance costs through access to digital technologies such as the Internet of Things, cloud computing and data analytics. Many promised benefits are, however, dependent on quality obtained sensors related technologies. In this work, we consider effect different levels deterioration quality, resulting partial information about underlying state system being monitored, by means sensors, condition-based policies. The may be either internal company or more informative external which is at a cost. We analyze structure optimal policy, where actions are perform maintenance, pay for sensor continue operation with only. show that policy consists most four regions based believed system. analysis allows us numerically investigate decision maker’s willingness respect level informativeness, when compared sensor, cost thereof.
