Robust Software Engineering Members Train General Electric Researchers on the AdvoCATE Safety Assurance Case Tool

Robust Software Engineering members trained General Electric researchers Drs. Abha Moitra and Heber Herencia-Zapana on the use of the the Assurance Case Automation Toolset (AdvoCATE), a safety assurance case tool, on August 6-7th, 2019. Safety/assurance cases represent the state-of-the-art in assurance technologies, especially for the certification of (increasingly) autonomous systems. General Electric has recognized the usefulness of AdvoCATE and plans on using it for their research on Unmanned Aerial Vehicles (UAVs), especially for their certifications. Training on AdvoCATE is done over two days, starting the first morning with training on the tool, followed by the development of simple assurance cases by students in the afternoon, and concluding with a review session of these assurance cases and the use of the tool with NASA experts Drs. Ewen Denney and Ganesh Pai.

Drs. Denney and Pai have developed assurance cases for several NASA missions (Mizoplex and Unmanned aircraft systems Traffic Management, UTM), some of them having been successfully reviewed and approved by the Federal Aviation Administration (FAA). General Electric is the first of a slew of aviation companies interested in using AdvoCATE including Lockheed Martin (for Unmanned Aerial Vehicle, UAV, applications), Aurora (for autonomous air taxis), Uber Elevate (for urban air mobility), Nutonomy, FiveAI, and BAE Systems.

BACKGROUND: Assurance cases provide an audit trail of assurance considerations from concept through operations, demonstrating that the risks associated with a specific system concern (safety in this case) have been identified, are well-understood, have been appropriately controlled, and that there are processes in place to monitor the performance and effectiveness of the risk management measures. AdvoCATE supports the development and management of safety/assurance cases, providing novel capabilities in automating their production, with applicability to safety-critical applications in aviation systems in particular.

NASA PROGRAM FUNDING: AdvoCATE funded by the Safe Autonomous Systems Operations (SASO) project, Airspace Operations and Safety Program (AOSP); System-wide Safety (SWS) project, Software Assurance Research Program (SARP); Aeronautics Research Mission Directorate
