Newport News Shipbuilding (NNS) has integrated videodisc media with expert system (ES) technology to create an innovative method for the delivery of submarine maintenance information. NNS has developed an ES entitled Scrubber which supports Navy efforts to modernize the distribution and use of technical information. Scrubber delivers maintenance information about the Carbon Dioxide Scrubber via menus or interactive dialogue. This videodisc-based ES can be easily adapted to facilitate maintenance and diagnostics of any complex piece of equipment or machinery.
