While multi-agent systems seem to provide a good basis to build complex control system, the variety of agent-oriented(AO) methodologies may become a problem for developer when it comes to select the best-suited methodology for a given application domain. To resolve the difficulties in the construction of C4I system on naval ship, we demonstrate a development architecture to blend various AO methodologies, which will pave the way for an unified and general AO methodology. Based on the architecture, a solution is proposed by combing two classes representative AO methodologies: Gaia method (general agent oriented method) and MaSE method (object-oriented extended method), which can provide straightforward connections between AO analysis results and OO software implementation.
