Kurzfassung: Agents are autonomous software components that can communicate with other agents. In the software engineering view agents can be regarded as generalizations of objects. Agents have knowledge of their environment, can act proactively and have a certain goal that they want to reach. Several agents that are communicating with each other to follow an individual or common goal are forming a society of agents called a multi-agent system. As a reference architecture Mulan, a Petri net-based agent platform on which multi-agent systems can be build, is introduced. In this work modeling techniques for agent interaction protocols are introduced. These interactions, also called conversations, are modeled with AUML diagrams and Petri nets. In the agent unified modeling language (AUML) some extensions are proposed for sequence diagrams as defined in the unified modeling language (UML). The agent interaction protocol diagrams that are developed in this work, which are used to model conversations, are a variant of these extended sequence diagrams. The aim in using the agent interaction protocol diagrams, which are restricted to certain elements and constellations of elements, is to achieve a modeling technique for Mulan-based agent interaction protocols that is consistent and helps the developers in the development process of Mulan protocols. These protocols, which are Petri nets, are implementations of agent interactions within Mulan. The presented work also introduces a straightforward approach for generation of Petri net code structures from AUML agent interaction protocol diagrams. This approach is based on the usage of net components that provide basic tasks and the structure for the Petri nets. Agent interaction protocol diagrams are used to model agent conversations on an abstract level. By mapping elements of the diagrams to net components, it is possible to generate code structures from the drawings. For this approach tool support is provided by combining net components with a tool for drawing agent interaction protocol diagrams. This combined tool is integrated in Renew (Reference Net Workshop) as a plug-in.
