This is a Decision Support/Expert System design proposal for the Naval Aviation Maintenance Control environment. A survey of contemporary literature concerning the use, development and implementation of such systems is conducted. A general examination of the decision maker's problem domain including the organization, requirements and constraints is presented. Design criteria are identified. An adaptive/prototype approach to design and system development is strongly recommended. Value analysis is suggested as the method for justification of the system. Specific recommendations for future development and implementation of the system are made.
