IoT-based real-time production logistics synchronization system under smart cloud manufacturing

Cloud manufacturing (CM) and Internet of things (IoT) are interlinked, yet most works only focused on one of them and take the other as a constituent technology unit. This is practically inadequate, especially for a highly service-driven manufacturing execution system which entails systematical CM supports to respond to the real-time dynamics captured from the IoT-enabled execution hierarchy. To deal with the dynamics occurring in production logistics (PL) processes, this paper investigates a dynamic PL synchronization (PLS) of a manufacturer adopting public PL services. Contemporary CM and IoT infrastructures are systematically integrated to enable a smart PLS control mechanism with multi-level dynamic adaptability. The S-CM operation framework, operation logic, and PLS infrastructure are presented with an industrial case, and the effectiveness is also demonstrated and analyzed.
