Deployed systems use increasingly complicated technology, increasing the difficulties of the tasks of both operators and maintainers. Technology must also be used to compensate for this increased burden. Midis is an example of this technology. The objectives of the effort are to determine the functional requirements for a successful midis capability, to determine what technologies provide this capability, to determine if the size/cost/utility provide a viable capability, and to examine how the maintainer can best utilize the functionality. Effort is proposed to 1) explore maintenance strategies utilizing the midis concept, 2) establish functional requirements for the midis capability to reduce operation and support costs, 3) perform a technology search for approaches to meet the needed capabilities, and 4) select technical approach(es) for a family of midis components.
