This book constitutes the proceedings of the 12th International Conference on Verification and
Evaluation of Computer and Communication Systems ( VECoS 2018) held at Grenoble France in
September 2018. The 11 full papers in this volume presented together with one abstract and two
invited papers were carefully reviewed and selected from 23 submissions. The aim of the VECoS
conference is to bring together researchers and practitioners in the areas of verification
control performance and dependability evaluation in order to discuss state of the art and
challenges in modern computer and communication systems in which functional and
extra-functional properties are strongly interrelated. Thus the main motivation for VECoS is
to encourage the cross-fertilization between various formal verification and evaluation
approaches methods and techniques and especially those developed for concurrent and
distributed hardware software systems.
