This book provides an extended state of the art on modelling multiagent systems, including examples for the different notations. Readers can quickly and effectively find which notations are best able to express the most appropriate multiagent concepts. A section on model-driven engineering and domain-specific languages proposes new approaches, worthwhile when existing notations do not provide all the necessary concepts. The book includes a theoretical discussion on notations and how to apply them, as well as a practical discussion on model-driven engineering and domain-specific language. Students and software professionals who design and develop multiagent systems in their applications will find the extended set of notations and feedback about these notations invaluable in deciding which modelling notation is best suited for their applications.Discussions on techniques such as model-driven engineering and domain-specific languages to transform models into code will also prove indispensable.
