Abstract
The healthy status of product reflects its ability to perform a specified task at a reliable and maintainable level in a certain period of time. It is significant for long-term storage and disposable products to estimate storage reliability, determine maintenance intervals, optimize storage cost and accomplish product tasks by means of establishing product health management center (PHMC) aiming at monitoring and managing product’s healthy state synthetically. This paper, regarding PHMC as a system of systems (SoS), builds a framework of PHMC based on the U.S. Department of Defense Architecture Framework (DoDAF), on the basis of comprehensive analysis of the characteristics of usage and maintenance for long-term storage and disposable product in maritime industry. The framework involves personnel, organization, and a variety of maintenance and support activities in relation to product health management. This framework describes the top-level design of the system with the help of high-level conceptual diagram. This paper also makes a specific design of the system in detail based on activity-based modelling (ABM) method. It shows that the framework is a useful practice in terms of adopting systems of system engineering (SOSE) ideas and DoDAF architecture to build PHMC system. Outcomes of the system implementation indicate that, for long-term storage and disposable product, PHMC can improve the efficiency of maintenance and support, at the same time it can reduce maintenance and support cost.
