Representing Navy tactical computer system knowledge for reengineering and integration

This article describes an ongoing project in representing knowledge about Navy tactical computer systems. The primary concern is for their continuing evolution and/or integration with other tactical systems. Following an introduction to this class of application and a review of how the Naval Surface Warfare Center is addressing the issue of extending the investment in these systems, the software process is examined and two alternative, incompatible paradigms are presented. The latter, which relies on the use of software knowledge, is described briefly, and an environment that implements this paradigm is presented as a proof of concept. Because the transfer of this paradigm to the desired Navy applications will not be completed in the near future, the article concludes with the presentation of a general framework for classifying Navy reengineering projects that should improve assessment and also aid in the building of a knowledge base to support the improved process model.Mr. Blum's work was supported in part by the U.S. Navy, Space and Naval Warfare Systems Command (SPAWAR) under contract N00039-89-C-0001, task VMAR9 with the Office of Naval Research (ONR) and the Naval Surface Warfare Center (NAVSWC).Ms. Moore's current affiliation is with the Defense Information Systems Agency, Arlington, VA 22204-2199.
