This proposal is concerned with identification of operator intensive functions associated with management of submarine weapons employment wherein application of Expert Systems/AI could mitigate overload during time critical evolutions and the eventual development of the appropriate Expert System prototype. Specifically, the objectives of this Phase I effort are: 1. Review submarine weapons, employment doctrine, weapon control operator responsibilities. 2. Establish evaluation criteria to be used for selection and prioritization of operator-intensive weapons and employment tasks. 3. Analyze the submarine weapons, employment doctrine, and weapon control operator responsibilities using the evaluation criteria established in (2) to develop candidate applications for AI solution. 4. Develop a conceptual system architecture which would include: a. Functional requirements.Baseline functional architecture. b. Identification of Candidate AI technologies and their application in the prototype system. 5. Prepare detailed Phase II plans which would include: a. Revised and complete prototype functional specification. b. Prototype system development. The results of Phase I will be summarized in a report containing:1. A prioritized list of operator-intensive weapons employment situations that merit an intelligent computer-based operational advisor. 2. A description of the analysis approach and evaluation criteria used to develop the list in (1). 3. A conceptual system architecture describing the fundamental expert system requirements, candidate fire control techniques and the artificial intelligence for data fusion.
