The MK 92 MOD 2 Fire Control System (FCS) is a fast reaction, lightweight, low manned, high
performance multi-function fire control system that gives a ship all the combat functions required for
independent tactical operation. The MK 92 MOD 2 FCS Maintenince Advisor Expert System
(MAES) was proposed to assist Fire Control technicians in the troubleshooting of this complex fire
control system. This thesis addresses the development of a fully functional prototype expert system
that provides troubleshooting expertise for performance parameter deficiencies noted in the Daily
System Operability Test (DSOT). Specific issues covered include: scope of the project, project
background, the expert system development life cycle, hardware and software selection, knowledge
acquisition, knowledge representation, knowledge implementation and lessons learned in the process.
This thesis perpetuates research aimed at deploying a diagnostic expert system for the MK 92 Mod 2 Fire Control System to 28 Oliver Hazard Perry class fast frigates. Referred to as the Maintenance Advisor Expert System (MAES) , this expert system is being jointly developed by the Naval Postgraduate School and Port Hueneme Division, Naval Surface Warfare Center (NSWC PHD). This thesis focuses on the long-term implementation issues related to deploying MAES to the fleet, integrating MAES into the formal training pipeline, and transitioning life cycle Support for MAES to NSWC PHD. MAES long-term implementation issues, which include hardware, software, documentation, and training requirements, are examined within the context of implementation factors and risks historically associated with deploying expert systems. Plans for deploying MAES to the fleet and integrating MAES into the formal training pipeline are provided. As part of the documentation necessary to transition life cycle support of MAES to NSWC, a System Level Description document is also provided
Approved for public release, distribution unlimited; The MK 92 Mod 2 Fire Control System (FCS) is a complex, maintenance intensive shipboard weapon system found primarily aboard the Oliver Hazard Perry class fast frigates (FFG-7). A maintenance advisor expert system (MAES) is being developed by the Port Hueneme Division of the Naval Surface Warfare Center and the Naval Postgraduate School (NPS) to assist the Fire Control Technicians aboard ship to better isolate faults in the MK 92 Mod 2 FCS. This thesis furthers the efforts of the project at NPS by investigating key hardware and software implementation issues that involve the deployment of the MAES to the fleet. Additional deployment issues addressed in this thesis include software documentation, integration of Performance and Calibration Modules, and the feasibility of the MAES being used as a training aid.
Approved for public release, distribution unlimited; This thesis is part of a software project to develop a diagnostic expert system for the MK 92 Mod 2 fire control system (FCS) daily system operability test (DSOT). The focus of this work examines the feasibility of applying multimedia, in the form of graphics, digital video, sound and CD-ROM technology, to the MK 92 Mod 2 Maintenance Advisor Expert System (MAES). The MAES application is intended for distribution to fleet sailors in order to increase readiness of the MK 92 Mod 2 FCS and decrease the need for outside technical assistance The MAES application is intended for distribution to the fleet on portable computers. In its current form, the MAES includes only text-based procedures and instructions to aid the user. This study examines whether it is technically feasible to employ high-resolution images, digital video, and sound to enhance the MAES and add impact to the current text outputs. Additionally, it explores the costs associated with each media. Given that the MAES will operate on a portable computer, the study also examines the limitations a portable environment places on multimedia technologies. Finally, this study recommends specific instances of incorporating multimedia in future implementations of the MAES.
The MK 92 Mod 2 Fire Control System (FCS) is a complex, maintenance intensive shipboard weapon system found primarily aboard the Oliver Hazard Perry class guided missile frigates (FFG-7). This system, based on 1970's technology, frequently requires extensive troubleshooting and supplemental support from shore-based technical experts. A maintenance advisor expert system (MAES) is being developed by the Port Hueneme Division of the Naval Surface Warfare Center (NSWC-PHD) and the Naval Postgraduate School (NPS) to assist the Fire Control technicians aboard ship to better isolate faults in the MK 92 Mod 2 FCS. This thesis furthers the efforts of the project at NPS by investigating key implementation issues that will affect the deployment of the initial version of MAES to the fleet. Additional deployment issues addressed in the thesis include incorporating lessons learned from deploying other expert systems in the armed forces, gaining support from individual chains of command, training MAES users effectively, involving MAES users in the implementation process, and changing hardware implementation issues. A training plan, implementation plan, and updated MAES user's manual for the initial deployment are included.; NA; U.S. Navy (U.S.N.) author
