creating and… - maintaining risk-, reliability- and availability models It is a workbench for non-experts to carry out advance analyses making it possible to model your system close to its design. It provides a closer link between your system and the safety model (digital twin) ![PumpingSystemSample](https://www.riskspectrum.com/hs-fs/hubfs/PumpingSystemSample.jpg?width=1292&height=815&name=PumpingSystemSample.jpg)   ## Software In Action   - The Knowledge Base - The graphical editor - Generate Fault Trees - Monte Carlo simulation - Availability and Reliability Assessment ##### Standardise Create a single, central repository of asset properties and risk models that everyone can use. Systems, equipment and their functional properties are defined and maintained in the ModelBuilder´s Knowledge Base (KB) The KB is like a template for equipment and systems E.g. for a pump: - Failure modes - Reliability data - Configurations - Dependencies (power supply, signal system, etc) ![KB&PumpingSystemSample-1](https://www.riskspectrum.com/hs-fs/hubfs/Images/KB%26PumpingSystemSample-1.jpg?width=773&height=513&name=KB%26PumpingSystemSample-1.jpg)   ##### Accelerate  Build and update risk and reliability models faster using RiskSpectrum ModelBuilder’s graphical user interface.  The ModelBuilder´s graphical user interface is used for creating/importing drawings, (e.g. P&ID, I&C, electrical single line diagram, etc) by pulling in objects defined in the Knowledge Base     ![Graphical PumpingSystemSample](https://www.riskspectrum.com/hs-fs/hubfs/Images/Graphical%20PumpingSystemSample.jpg?width=777&height=488&name=Graphical%20PumpingSystemSample.jpg)   ##### Automate  Fault trees are automatically generated from the ModelBuilder and exported to RiskSpectrum PSA ![Generate FT](https://www.riskspectrum.com/hs-fs/hubfs/Images/Generate%20FT.jpg?width=1068&height=404&name=Generate%20FT.jpg)   ##### Automate Run the built-in Monte Carlo simulation tool YAMS to calculate your system's reliability and availability ![Miniplant Availability](https://www.riskspectrum.com/hs-fs/hubfs/Images/Miniplant%20Availability.jpg?width=1254&height=529&name=Miniplant%20Availability.jpg) ##### Improve your Availability and Reliability Assessment How can model-based availability assessment be represented in models and knowledgebases in RiskSpectrum ModelBuilder and what types of results can be produced? Read all about it in the document on the right. It proposes methods for validation models and explore possibilities for automatic search for design optima.
