Hierarchical object-oriented modeling of fault-tolerant computer systems

A hierarchical, object-oriented modeling language for the specification of dependability models for complex fault-tolerant computer systems is overviewed. The language incorporates the hierarchical notions of cluster, operational mode and configuration and borrows from object-oriented programming the concepts of class, parameterization, and instantiation. These features together result in a highly expressive environment allowing the concise specification of sophisticated dependability models for complex systems. In addition, the language supports the declaration of symmetries that systems may exhibit at levels higher than the component level. These symmetries can be used to automatically generate lumped state-level models of significantly reduced size in relation to the state-level models which would be generated from a flat, component-level description of the system.Postprint (published version

Guest editorial to the first international workshop on performability modelling of computer and communication systems

The papers in this issue of Performance Evaluation all deal with performability modelling of computer and communication systems. This was the topic of the First International Workshop on Performability Modelling of Computer and Communication Systems (PMCCS-1), held 7-8 February 1991, at the University of Twente, Enschede, the Netherlands
