A methodology for agent-oriented analysis and design

Michael Wooldridge, Nicholas R. Jennings, David Kinny
1999 Proceedings of the third annual conference on Autonomous Agents - AGENTS '99  
The methodology is founded on the view of a system as a computational organisation consisting of various interacting roles.  ...  This paper presents a methodology for agent-oriented analysis and design.  ...  It is assumed that the goal is to obtain a system that maximises some global quality measure, but which may be suboptimal from the point of view of the system components.  ...
