Efficient Integration, Validation and Troubleshooting in Multimodal Distributed Diagnostic Schemes

In general, development and validation of diagnostic models for complex safety critical systems are time and cost intensive jobs. The proposed Phase-II effort will automate some vital processes essential in developing integrated diagnostic schemes and cost-effective revalidation of the integrated models. The automated processes, resulting from this effort will be incorporated as tools in TEAMS Design and Analytic Platform. For reducing the burden of testing diagnostic models, capability for automatically generating test cases, regression test suites along with the options for their playback will be developed under this effort. Additionally, an option for efficient diagnostics and troubleshooting in multi-mode systems will be introduced in TEAMS via this SBIR effort. To ensure the readiness of the TEAMS tools and options developed through this effort, those will be verified and validated with one or more NASA's ground support systems that are associated with the ARES or Constellation Program Ground Support. Collectively, these achievements will significantly reduce the time and cost in developing and better utilizing large scale fault diagnostic systems using TEAMS.
