Expert Systems (ES) are characterized by containing the knowledge of a single human expert. Most ES today operate in a 'standalone' basis, providing expertise in a specific domain. However, managers making strategic decisions on complex topics require the coordination assessment and evaluation of knowledge from multiple human experts. Standalone knowledge bases should be loosely or tightly coupled together to form a network of coordinated Distributed Expert Systems (DES). To facilitate this, a 'meta-ES' could be designed to access and control these distributed knowledge bases, thus providing users with a single entry point into a vast knowledge network. In the U.S. Navy submarine is constructed of compact, high energy systems, safety is paramount to prevent both personal injury and material damage during maintenance evolutions. The Ship's Duty Officer (SDO) is responsible for the safe and effective execution of all maintenance aboard ship. Thus, he needs to be knowledgeable of how maintenance on one system will affect the operation of other systems. Since the SDO requires many sources of expertise, automating a submarine maintenance process is an appropriate DES application.
