QoS modeling and analysis for manufacturing networks: A service framework

The popularity of networks in manufacturing is continuously growing, and the quality of service (QoS) has become one of the most intriguing aspects for both the theory and practice of manufacturing networks. The concept of QoS for manufacturing networks is discussed, together with the classification and modeling of the QoS issues. Then, this paper presents a QoS-aware service framework integrating the QoS mechanisms from both the MGrid technology and communication networks, so that provides an integrated QoS guarantee for manufacturing systems under network environment. In order to evaluate the efficacy of the framework, a prototype implementation have been performed and analyzed. The analysis results demonstrate that the framework, QASF-MNet, is able to effectively satisfy the various performance requirements posted by the applications of manufacturing networks.
