Diagnosis and Handling of Exception in Cloud Manufacturing

Service composition is the main operation mode of cloud manufacturing (CMfg), but it is vulnerable to exceptions. To keep the robustness of service composition at processing stage in cloud manufacturing, this paper investigated the whole execution process of service composition, and established an adaptive adjustment framework of it. This framework consists of anomaly detection, anomaly diagnosis and anomaly handling. This framework is driven by data, which are collected from the weakest links of the service composition through Internet of things (IoT) technology and monitoring technology. Besides, all data processing and the adjustment strategies are operated by the cloud manufacturing platform.
