Journal Paper: Performance and Reliability Prediction

An article summarizing results from the EU-Project Q-ImPrESS was accepted for publication in Springer’s Journal on Empirical Software Engineering. It describes how we modelled an industrial control system for performance and reliability predictions. The paper discusses the prediction accuracy as well as the effort for creating the respective models. The paper is based is an extended version of a paper from ISSRE 2010 and another one from ICSE 2011.

New paper: An Industrial Case Study of Performance and Cost Design Space Exploration

This paper shows how our software tools Palladio and PerOpteryx were used in capacity planning for a web-based remote diagnostics system at ABB. It will be presented at the International Conference on Performance Engineering (ICPE 2012) in April in Boston, US.

PerOpteryx results: CPU Utilization vs. costs; each dot represents a generated design alternative for the system. The diagram shows the trade-off between performance and costs.

Automated Transformation of Component-based Software Architecture Models to Queueing Petri Nets

New paper accepted at MASCOTS 2011: “This paper contributes a formal mapping from PCM to QPN models, implemented by means of an automated model-to-model transformation as part of a new PCM solution method based on simulation of QPNs. The limitations of the mapping and the accuracy and overhead of the new solution method compared to existing methods are evaluated in detail in the context of five case studies of different size and complexity. The new solution method proved to provide good accuracy with solution overhead up to 20 times lower compared to PCM’s reference solver.”
