Policy-based self-management of industrial service systems

Service-orientation supports the construction of flexible and comprehensive industrial applications. The growing scale and complexity of the applications, however, demand for enhanced self-management functions providing efficient self-adaptation and repair mechanisms. We propose the approach of policy-controlled self-management which has been developed and successfully tested in the context of Web Service based control applications. We use hierarchically structured management policies where high-level policies serve as abstract definitions of management objectives and low-level policies represent concrete rules for resource monitoring and correcting interventions. The definition, analysis, refinement and deployment of the policies are supported by an interactive graphical modeling tool.
