Multi-Agent Organizational Structure: specification and validation

Abstract To design complex Multi-Agent Systems (MAS), the use of high-level abstraction concepts such as roles, protocols, and groups, makes the task relatively easier and closer to the reality of the system or domain that we want to simulate or create. These concepts were introduced through the multi-agent Organizational Models (OM) which can be seen at two levels: i) an abstract level which is the Organizational Structure (OS) and ii) a concrete level which is the Concrete Organization (CO) to be deployed and executed. This article is dedicated to the formal specification and validation of the identified roles in the Organizational Structure before a real deployment to generate systems with organizations exhibiting good qualities. Also, a proposal of a set of steps to automatically generate the code of the designed agent will be presented. In addition, the evaluation of some organizational aspects will be done at the abstract level makes it possible to adjust the design to remedy any failures before a real instantiation. The application domain used in this context, is a Cooperative Information Gathering System (CIGS) for travel organization.
