UML modeling based on Extendsim and its application in warship maintenance support

Three-echelon maintenance support process of warship is a dynamic and complex process. Combining with the advantages of Extendsim and UML, the UML models of warship maintenance support process were built, which including entity collaboration diagram, class diagram and activity diagrams, and a method of transforming UML models into Extendsim models was proposed. Based on these, warship maintenance support simulation software architecture named MVC (Model-View-Controller) was designed and realized. Finally, by the integration and simulation experiment of a three-echelon maintenance support simulation system of warship, the paper made an analysis of the influence factors on the capability of support system, and the simulation results proved that simulation system can simulate accurately the process of warship maintenance support.
