Define criticality parameters for component functions to support the automated generation of a range of safety and risk assessments that are required for the design and support of safety/mission-critical equipment, including failure mode, effects and criticality analysis (FMECA) and functional fault tree analysis.
Increase productivity and reduce costs by identifying all possible failures in a design or a product in an objective manner. Produce standard failure mode and effects analysis (FMEA) and FMECA artifacts directly from the digital risk twin; providing the benefits of a reusable/scalable model and the ability to generate standard documents as a by-product of the modeling process at any given point in development process.
Ensure that failures are described, displayed and reported in a consistent and traceable manner. Failure diagrams are a graphical representation of the causes, mechanisms and faults that can lead to loss of function in the system, described based on a dedicated failure taxonomy. Use a graphical interface to represent the physical processes which can lead to an item’s failure (cause, mechanism, fault, symptom) and how these can propagate throughout the system (automated dependency mapping). Failure diagrams are developed for each item and used to define how a component can fail based on the physics of failure. Each fault has failure conditions, compensating provisions and detection methods which can be displayed in the FMECA report.
Identify the dependencies of engineering risks in a specific system configuration using functional fault tree analysis (FTA). The FTA is generated automatically from the digital risk twin to identify potential causes of failures, their relative importance and the probability of occurrence.
Perform functional hazard assessment (FHA) at both platform and systems level to identify potential functional failures and classify the hazards associated with specific failure conditions. The FHA is developed early in the development process and is updated as new functions or failure conditions are identified.
