Research on credibility support mechanism of manufacturing cloud service based on classified QoS

Abstract

In order to make the manufacturing progress go on smoothly for cloud manufacturing environment, a credibility support mechanism of the manufacturing cloud service is raised based on classified QoS. With the mechanism, a manufacturing cloud service model describes the environment information and the QoS level explicitly, and builds the adaptive control logic in itself. According to environment changes and rules in the rule library, the manufacturing cloud service uses an adaptive algorithm and adjusts the QoS level. There are three dynamic adjustion types which drive services to transform between different states. Besides to guarantee the service performance, a credibility evaluation system of services is introduced in to quantize the QoS.
