Study on Vessel Maintenance Support System Modelling Based on DODAF

The vessel maintenance support system, which consist of aboard and onboard two parts, is different from the other equipments, with the characteristics of tasks varied, complex structures and onerous business. It is a virtual system rather than a material system. So the traditional modelling method which is used to describe the material objects has some defects of long communication period, weak reusability and poor expansion in describing support system in design process, which apparently cannot meet the current demands. It is imperative to introducing standardized design and modelling approach to establish the vessel support system. The study firstly analyses the function, organization, resource and operation of vessel support system. The support system modelling method is introduced based on the analysis of different view products in DODAF framework. The support system model, which is consists of organization model, activity model and information exchange matrix is given based on active based model. It can provide guidance in support system design, support concept generation under new situation, even in integrated joint operation system design in the future.
