Abstract

The US Navy Integrated Diagnostic Support System (IDSS) program is developing software tools required for a systems-engineering approach to providing an improved fault-isolation capability for the operational-level maintenance technician. The success of the diagnostic process is seen to depend on the use of testable designs, development of test procedures based on the optimum design, authoring of the execution software, and analysis of results of diagnostic sessions as feedback to the system expert-knowledge database. The IDSS software tools are described, and the status of the IDSS research and development effort is presented. The current demonstration software runs on two hosts at the present time: a Sun workstation operating under Unix and a MicroVAX II minicomputer running under MicroVMS. All software is written in Ada
