The International Conference on Quantitative Evaluation of SysTems (QEST) is the leading forum on quantitative evaluation and verification of systems and networks based on their probabilistic, temporal and other non-deterministic aspects.

Performance metrics of interest include response time, reliability, availability, safety, security, survivability, correctness, timeliness, and efficiency. Areas of interest include modelling formalisms and methodologies, measurements, analytical and numerical evaluation, simulation, verification, and theory of stochastic, non-deterministic and concurrent behavior. Also of interest are case studies showing the role of quantitative evaluation in the design of systems including computer architectures, distributed and fault tolerant systems, communication systems, embedded systems, web-based systems, and safety-critical systems.

Tools for supporting the practical application of research results in all the above areas are of special interest for QEST and therefore tool papers are sought.
