Finding a Structure: Evaluating Different Modelling Languages Regarding Their Suitability of Designing Agent-Based Models
Digital Human Modeling and Applications in Health, Safety, Ergonomics and Risk Management. Human Body, Motion and BehaviorPages 201–219https://doi.org/10.1007/978-3-030-77817-0_16AbstractSeveral approaches to standardize the creation of agent-based models exist, but there is no perfect way to do it yet. In this study we analyze, whether two modelling languages (i*Star, UML) can help in designing agent-based models. We identified ...
