Workbench for safety analysis

For complex safety and risk assessments APSYS developed SimfiaNeo. A highly configurable set up allows the modelling of functional and dysfunctional system behaviour, supporting dedicated safety and reliability studies up to complex critical system modelling.

Model-Based Safety Assessment (MBSA) with SimfiaNeo allows an automated modelling and analysis of system safety based on a functional model with failure propagation.

For RAMS studies (Reliability, Availability, Maintainability, Safety) SimfiaNeo supports a reliability modelling based on realistic scenarios, processes, system integration and system environments.

By applying SimfiaNeo as continuous safety analytics solution over the whole product-life-cycle waste, cost and production in-efficiencies can be identified and eliminated.

SimfiaNeo is used for our consulting activities while at the same time it is deployed at clients (Aerospace, Energy, Transportation, Defence,…). It can be also used for the simulation of future mobility and infrastructures.

SimfiaNeo is based on AltaRica language, offers dedicated work flow extensions and has been recognised for more than 20 years for its advanced capabilities.

Added value

  • Model-Based analysis of the system
  • All functions, equipment and events in one single model
  • Identification of risk drivers and critical events
  • Fast updates during iterations and rapid study of architecture alternatives
  • Read to deploy system extensions covering specific industry needs
  • Generation of customised reports
  • Allows the simulation of design modifications to achieve minimum failures or to increase mean time between failures
  • Helps to identify suitable maintenance policies/strategies


  • Based on AltaRica language
  • Highly adaptable interface (multi screen, adaptable views, …)
  • Top-down modelling, bottom-up computation
  • Customisable definition of system dysfunctions, risks and threats
  • Individual library set-up for events and studies
  • Graphic visualization of cause-effect relations on connectors and impact
  • Logical loops detector
  • Step-by-step simulation
  • Replay scenario to avoid regression
  • Generation of FMECA
  • Identification of all event combinations leading to a failure, disruption or system dysfunction situation
  • Automatic verification of user-defined rules at each iteration including a common-cause identification
  • Monte-Carlo based computation for system performance evaluation
