Features and Characteristics:

• A graphical user interface to create and edit models.
• Event Trees, including branches with more than two options.
• Architectures: automatic creation of fault trees based on schematic diagrams.
• Extended Fault Trees: Monte-Carlo simulation provides many gate types the enable modeling of practically any particular system to be modeled and evaluated with high accuracy.
• Extended Reliability Block Diagrams: different parallel structures available
• Extended Markov models: not only transition rates but also transition probabilities are supported, and events at discrete times (e.g. restoration).
• Conversion of Fault Trees to Reliability Block Diagrams and vice verse.
• Conversion of Fault Trees to Markov models, including common causes and condition events.
• Steady state quantitative evaluation of all models.
• Transient (time-variant) evaluation of Fault Trees and Markov models.
• Supports modularization of Fault Trees.
• Supports linking between models.
• Many occurance/failure models for basic events.
• Easy handling of common cause failures, even through transfer-gates and combination gates.
• Graphical output of unavailability, unreliability and occurance rate (failure frequency) as function of time.
• Modeling, simulation and graphical analysis of complex components with different failure modes (safe and unsafe) with time variant rates, incl. detailed calculus of the characteristic values (e.g. b10, b10_d, MTBF, MTBF_d etc.).
• Export of all graphical representations in bitmap (PNG) or vector graphics format (SVG, DrawingML).
• Export of the prime implicants (minimal cut-sets) in HTML or CSV format.
• Export of transient data in CSV format.
• Analysis of the importance of basic events or generic basic events to the top event of a Fault Tree or Markov model.
• No proprietary or binary file formats: all data is stored in XML text files.
