WHILE AUTOMATION TECHNOLOGIES ADVANCE FASTER THAN EVER, GAPS OF RESILIENCE CAPABILITIES BETWEEN AUTONOMOUS AND HUMAN-OPERATED SYSTEMS HAVE NOT YET BEEN FILLED IN PROPORTION. ACCORDINGLY, ATANALYTICS, IN COLLABORATION WITH THE CENTER FOR RELIABILITY AND RESILIENCE ENGINEERING (CRRE) OF THE B. JOHN GARRICK INSTITUTE FOR THE RISK SCIENCES AT UCLA PROPOSES TO DEVELOP A METHODOLOGY AND TOOLKIT FOR ASSURED RESILIENCE OF AUTONOMOUS SYSTEMS (ARAS). THE CENTRAL PART OF THE ARAS METHODOLOGY CONSISTS OF TWO GAP FILLERS: (1) AN ONTOLOGY-DRIVEN DATABASE SUPPORTING RESILIENCE ENGINEERING ACTIVITIES AND RESILIENCE MODELING, AND (2) A RESILIENCE ASSESSMENT AND OPTIMIZATION EMPLOYING A HYBRID CAUSAL LOGIC (HCL) BASED SOFTWARE PLATFORM FOR RESILIENCE ENGINEERING SUPPORT. THE DATABASE INCLUDES RESILIENCE ENGINEERING PRINCIPLES, ARCHETYPE MISSION SCENARIOS, AND METRIC META MODELS. WITH THE HCL-BASED RESILIENCE ASSESSOR, A HIGH-LEVEL MODEL AT THE TOP LAYER ENABLES RESILIENCE METRICS TO BE DEFINED AT THE MISSION-SCENARIO LEVEL (OR CONOPS LEVEL) AND BE SUBSEQUENTLY MAPPED TO THE LOWER-LEVEL MODELS TO CAPTURE SYSTEM SPECIFICS. OUR INNOVATION WILL BE A SIGNIFICANT STEP FORWARD TO RESILIENCE ENGINEERING STANDARDIZATION SINCE (I) THE DATABASE (A KNOWLEDGE HUB) AND RESILIENCE MODELS WILL BE ONBOARD RESOURCES ENABLING BOTH DESIGN-FOR-RESILIENCE AND ONBOARD DECISION MAKING FOR RESILIENCE ASSURANCE, AND (II) THE HCL METRICS-IN-THE-LOOP METHODOLOGY IS INHERENTLY GENERALIZABLE FOR DIFFERENT LEVELS OF SYSTEM ABSTRACTION, LIFE-CYCLE, AND MISSION PHASES.
