Knowledge-driven service orchestration engine for flexible information acquisition in industrial cyber-physical systems

Cyber-physical systems attract attentions from many domains including industrial automation recently. Cyber-physical production system or industrial cyber-physical system is considered as key to achieve collaborative automation systems. The service-oriented architecture is often linked with industrial cyber-physical systems to lift flexibility and interoperability. By adopting service-oriented architecture in industrial cyber-physical systems, a new way of information acquisition is enabled by dynamically composing services according to requests. In this paper, a knowledge-driven service orchestration engine is introduced for process requests from human or devices and collect information automatically by assembling services dynamically. The service composition process is described using a room lighting system example. Tools required by the service orchestration engine and future development plan are provided.
