....emerge from a design process. For this, we mm to organizational theory and strategic alliances for guidance. The purpose of this paper is to present further work on the development and application of a set of architectural styles for multi agent systems motivated by these theories and reported in [Ko101, Fux01]. These styles are the structure in 5, the joint venture, the takeover, the bidding, the hierarchical contracting, the arm s length, the matrix, the co optation . We discuss here the structure in 5 and the joint venture. The styles are modeled using the strategic dependency model of i [Yu95] ....

....is an instance of such a style and pattern. We also propose to relate them to social or agent patterns (e.g, the broker, matchmaker, embassy, facilitator . and lower level architectural components involving (software) components, ports, connectors, interfaces, libraries and configurations [Fux01, Ko101]. We are still working on contrasting our structures to conventional styles [Sha96] and pattems [Gam95] proposed in the software engineering literature. To this end, as mentioned in the paper, we are defining algorithms to propagate evidences of satisfaction and denial of each conventional or ....

Taking real world organizations as a metaphor, architectural patterns for MAS can be based on models from organization theory as described in [Fux01a, Ko101, Gio02]. The structure in 5 is a well understood idiom from organization theory detailing the internal structure of an organization. In the paper, we propose to use it to design MAS architectures.

Using them, we view a software system as a social organization of coordinated autonomous components (or agents) that interact in order to achieve specific, possibly common goals. We adopt (some of) the styles [Fux01] defined in organizational theory and strategic alliances to design the architecture of the system, model them with i , and specify them in Telos [Myl90] In i , a strategic dependency model is a graph, in which each node represents an actor, and each link between two actors indicates that one ....

....additional detail for each architectural component of a system. In our case, this includes actor communication and actor behavior. To support this phase, we propose to adopt agent specifications proposed by FIPA (Foundation for Intelligent Agents) 12] notably agent role and patterns (see [14, 20]) that can be found in agent communication languages like FIPA ACL [12] or KQML [12] For instance, the matchmaker agent pattern locates a provider corresponding to a consumer request for service, and then hands the consumer a handle to the chosen provider. Contrary to the broker pattern who ....
