Multi-agent systems (MASs) and object-oriented systems (OOSs) differ in many respects. Traditionally, OOSs are composed of objects whose properties are attributes and methods and interact through method calling. MASs are composed not only of objects but of different elements (such as agents, organizations and others) that have different properties and interact in different ways. MASs require mo...

The Unified Modeling Language (UML) is a language for the specification, visualization, and documentation of object-oriented software systems [The Unified Modeling Language User Guide, 1998]. However, UML cannot describe in an explicit manner the mobility requirements needed for modeling mobile agent-based software systems. In this paper, we present M-UML, our proposed extension to UML covering...

We discuss questions about user centric development of business process modeling notations. In the center of our research there is a fully featured multi-enterprise business process platform (ME-BPP) based on the concepts of agent-based business processes, which builds on the formal foundations of the subject-oriented business process management methodology (SBPM). The platform is implemented b...

Since 1995, our team has been developing a simulation platform called CORMAS (common-pool resources and multi-agent systems). It provides facilities to build and analyze agent-based models (ABMs) that represent ecosystems where various human activities compete for the use of natural resources. Few agent-based simulations can be mathematically proven, but they can be analyzed inductively. It is ...
