“…The Multiagent Systems Engineering ( MaSE ) methodology (DeLoach, S. A., Wood, M. F., Sparkman, C. H., 2001) is composed of two phases: The analysis phase proceeds in three steps: capturing goals, applying use cases and refining roles; the design phase comprises four steps: creating agent classes, constructing conversations, assembling agent classes and system design. Aalaadin (Ferber J, Gutknecht O., 1998) is based on the concepts of agent, group and role and proposes a three phases process (Augeraud M., Collé F., Sarramia D., Boussier J.-M., 2006): The analysis phase is used to identify the functions of the system; the design phase allows to identify groups and roles through organizational structures diagrams as well as the description of the interactions between roles by sequence diagrams; the last phase begins with a choice of agent architecture and instantiates the organizational structures in concrete organizations. The Prometheus methodology (Padgham L., Winikoff M., 2002) consists of three phases: The system specification phase to identify the basic functionalities of the system: the input, the output and any shared data source; the architecture design phase uses the output to determine which agents the system will contain and how they will interact; and the detailed design phase focuses on developing the internal structure of the agents.…”
