Conceptual Data Model Evolution in Joint Strike Fighter Autonomic Logistics Information System of Systems Engineering
Abstract
The complexity of modern systems engineering projects has dramatically increased over the past two decades. One reason for this complexity is the challenge of developing a complete and correct conceptual system data model. Systems being developed must use information from an increasing number of information sources including legacy systems, GOTS, COTS and custom databases. Conceptual system data models must constantly evolve and be verified to accommodate system enhancements or COTS package upgrades. The task of verifying conceptual model correctness is largely a manual task with limited tools. This paper describes current research to develop tools and techniques which allow systems engineers to perform comparative analysis between the conceptual data model for a new system and the physical data models represented in applications, databases and related systems. The Joint Strike Fighter (JSF) Operations and Support budget will be reduced from two thirds to one half the total life cycle cost [JSFSDD02]. An efficient and affordable JSF maintenance program is critical to the overall project success and ultimately the war fighter. This research is directed specifically to JSF but has broad applicability to any project with requirements to integrate existing information systems while maintaining a consistent enterprise model.
