The agent-oriented approach has emerged as a novel and popular paradigm for modern management information system analysis, design and implementation. In this paper, the authors concentrate on the design of a real application: SPAERIS(Shipping pollution accident emergence reflecting information system), using AUML(Agent Unified Modeling Language). Furthermore, we explored and discussed the strengths and weaknesses of AUML, and made some appropriate extension of the approach to better realize our design objectives. The research produced a methodological basis for the analysis, design of distributed management information system. The SPAERIS has been delivered to the users and is on running.
