This book constitutes the thoroughly refereed post-conference proceedings of the 18th
International Workshop on Multi-Agent-Based Simulation MABS 2017 held in Sao Paulo Brazil
in May 2017. The workshop was held in conjunction with the 16th International Conference on
Autonomous Agents and Multi-Agent Systems AAMAS 2017. The 15 revised full papers included in
this volume were carefully selected from 23 submissions. The topic of the papers is about
applying agent-based simulation techniques to real-world problems focusing on the confluence of
socio-technical-natural sciences and multi-agent systems with a strong application empirical
vein.
