Key Areas influencing Safety and Resilience

The software for CPS/IoT needs to

  • Process events and analyze data (in-motion) in real time 
  • Consider the Context for data filtering 
  • Act on unanticipated errors and exceptions in real time (within milliseconds or microseconds) – E.g. Time window to react to an overloaded distribution substation in a power grid to avoid a power disruption 
  • Make ethical decisions on the spot – Runaway truck with hazardous materials – Military drone for a target in an urban location – Cargo train  on a collision course 
  • Self-protect from unauthorized accesses for integrity


Key Areas influencing Safety and Resilience
  • Modeling and Architecture 
  • Constraints 
    • Budget 
    • Time 
    • Resources & Skills 
    • Current system & process (paradigm?) 
  • Statutory requirements and Regulations
  • Governance 
    • Organization and Culture 
    • Model and Process 
    • Decision making process
  • Methodology 
    • Development method 
    • Interdisciplinary communication & collaboration
    • System validation method 
  • Business Model & Process 
    • Process, Function, Information, Security, Integration, … 
    • Uncertainty (assumptions) 
    • Ambiguity (source of defects) 
  • Target Operating Model
