Smart Anything Everywhere

Cyber-Physical Systems Engineering Labs is part of the Smart Anything Everywhere initiative.

This project has received funding from the European Union's Horizon 2020 research and innovation programme under grant agreement No 644400.

HAZOP-UML

HAZOP-UML is a model-based safety analysis method to identify operational risks due to human-robot or robot-robot interactions. This method adapts the HAZOP (Hazard Operability) technique to analyze deviations of the UML diagrams (Unified Modeling Language).

HAZOPUML

To explore in a systematic way the possible deviations, we provide guide words tables for UML use cases, messages of sequence diagrams, and state machines. Those guide words tables help the safety analyst to imagine possible deviations for every elements of those dynamic models. Those deviations are then reported in HAZOP tables, where causes, consequences, and recommendations are formulated. This process produces lists of hazards, recommendations, and hypotheses. HAZOP-UML provides the following benefits:

  • simple (training and application),
  • applicable at the first step of the development process,
  • limits the combinatory explosion,
  • consistent with system models, and inherits of system modeling benefits: traceability and modifiability,
  • easily supported by a computer assisting tool.

Case Studies

You can read case studies of organisations which have evaluated HAZOP-UML previously

  • The MIRAS Case Study. ANR-MIRAS (Multimodal Interactive Robot of Assistance in Strolling) is an assistive robot for standing up, sitting down and walking, and also capable of health-state monitoring of the patients.
  • The SAPHARI Case Study. SAPHARI (Safe and Autonomous Physical Human-Aware Robot Interaction) is a mobile manipulator operating in a manufacturing setting accessible to human workers.
  • The PHRIENDS Case Study. PHRIENDS (Physical Human-Robot Interaction: depENDability and Safety) is a mobile robot with a manipulator arm, designed for workshops and factories with human workers.
