System modeling tools can help you calculate the reliability, availability, and cost metrics of systems with complex interdependent component relationships. Relex OpSim provides the block diagram and phase diagram tools for system modeling combined with powerful optimization and simulation analysis techniques. Easy, intuitive graphical tools and a wide selection of maintenance-related calculations let you model complex system configurations including those with parallel, load-sharing, and standby redundancy types. Determine optimal values for spares, preventive maintenance intervals, and inspection intervals while accounting for multiple facets of component maintenance, such as spares availability, personnel requirements, and degradation factors.

Easy-to-use graphical layout tools allow you to create reliability block diagrams or phase diagrams.
Assign a wide range of maintenance parameters for each component to account for imperfect repairs, spares allocation, and personnel resources.
Create clear, vivid graphs displaying key system metrics, such as Total Cost over Time, using easy, wizard-based design tools.

Benefits

  • Provides a wide range of system metrics, including Failure Rate, MTBF, MTTF, Reliability, and Availability, among others

    Supported Calculations:

    • Failure Rate
    • MTBF
    • MTTF
    • Reliability
    • Availability
    • Expected number of failures
    • Optimize spares
