The ESM'2015 (The 29th annual European Simulation and Modelling Conference) is the original international European conference concerned with state of the art technology in modelling and simulation. ESM'2015 aims to provide an overview of academic research in the field of computer simulation. A number of major tracks of simulation research are presented next to specific workshops, which capture the art and science of present-day simulation research. ESM'2015 covers simulation methodology, simulation applications, specialised workshops, the exhibition and last but not least the poster sessions for students.
