The International Workshop on Verification and Evaluation of Computer and Communication Systems (VECoS) was created by a Euro-Maghrebian network of researchers in computer science. The aim of VECoS workshop is to bring together researchers and practitioners, in the areas of verification, control, performance, Quality of Service (QoS), dependability evaluation, and assessment to discuss the state of the art for solving the challenges facing us today in various modern computer and communication systems in which functional and non functional properties are strongly mixed. Thus, the main motivation for VECoS is to encourage the cross-fertilization between verification and evaluation approaches, methods and techniques especially those based on the specification formalisms for concurrent, distributed and harward systems. Beyond its technical and scientific goals, another main purpose of VECoS is to promote collaboration between participants in research and education in the area of computer science and engineering.
