Specifying resource-centric services in cyber physical systems

A service-oriented view of Cyber-Physical Systems (CPS) is a good platform for managing global supply chain management, service acquisition and service provision. A necessary condition for complex service delivery is that resources required for complex services are of high quality and are available at service execution times. Therefore in a resource-centric service model, both resource quality and service quality using that resource are explicitly stated. In this paper a cascaded specification approach is discussed for describing resource types, services offered by resource, and a cyber configured service (CCS) that package physical services. Energy support from internal-combustion engine is regarded as a resource-centric complex service and discussed as a case study to illustrate our specifying and modeling approach.
