Study on equipment health management system modelling based on DoDAF

With the development of the technology of prognostics and health management (PHM) and the improvement of integrated diagnostic technology for equipment, the maintenance support strategy of ordnance equipment gradually evolves from traditional corrective maintenance (CM) with a small amount of preventive maintenance (PM) to condition-based maintenance (CBM) and automatic logistic system (ALS) in last decade. In order to achieve those new maintenance support strategies, an appropriate equipment health management system must be established. But effective and feasible methods and tools of designing and modelling of equipment health management system is lacked at the present stage. Aiming at the requirements, this paper puts forward the descriptions of the equipment health management system from the different aspects of organizations, activities, information flows with the view products in DoDAF. The paper analyzes the relationship of nodes in the system, system architecture, activities, information and business flows among departments in the system, and discusses the interfaces among different organizations, functions of the system and the mapping relation between different functions and organizations with Operation Views (OV).Through the above analysis, the connections among different organizations, staffs, resources, functions in the equipment health management are established. And the progress of equipment health management system modelling is also proposed. The result shows that the model is intuitional, easy to understand and involves all the essential information of the system. The model can provide effective technical support for the design and establishment of the technology equipment health management system.
