ANALYTICS

The Relyence RBD calculation engine computes a variety of your most vital reliability and availability metrics.

ANALYTICS

Relyence RBD calculates all your most critical metrics for evaluating system performance: reliability, unreliability, availability, mean unavailability, total downtime, failure frequency, path sets, and more. The Relyence RBD calculation engine encompasses a diagram analyzer to determine the most efficient computational methods, and a mathematical engine to perform quick and accurate calculations using both exact and simulation analyses.
Relyence RBD Calculations
Relyence RBD supports a large array of reliability and availability metrics.
Metrics

Relyence RBD calculates an array of reliability and availability metrics, any and all of which can be optionally enabled according to your needs. Available Relyence RBD metrics include:

  • Reliability
  • Failure rate
  • Availability
  • Mean availability
  • Hazard rate
  • Total downtime
  • Unreliability
  • Equivalent failure rate
  • Unavailability
  • Mean unavailability
  • Failure frequency
  • Expected number of failures
  • Steady-state MTTF
  • Steady-state MTTR
  • Steady-state MTBF
  • Steady-state Availability
Analytical and Simulation Methods

Depending on the complexity and layout of your RBD, and the selection of metrics to compute, the Relyence RBD calculation engine determines the optimal approach for calculation by analyzing your diagram. The Relyence RBD calculation engine includes both the ability to perform analytical, or exact, calculations and employ its Monte Carlo simulation engine if needed. You can optionally choose to always perform simulation analysis if you prefer. Calculation preferences also allow you to set the number of iterations to perform when using simulation, the number of failures required to reach steady state, and set the random number generator seed.

RBD Analytics Calculator
Relyence RBD includes a built-in Analytics Calculator to compute point-based metrics for your diagrams.
Analytics Calculator

The Relyence RBD Analytics Calculator can be used to calculate various point-based RBD metrics. Metrics available for calculation include Availability, Bearing Life (used to calculate B10 Life), Failure Rate, Mean Life, Reliability, Warranty Time, and more.

Relyence RBD’s smart calculation engine will calculate the metrics using analytical methods, Monte Carlo simulation techniques, or a combination of the two. In addition, the Analytics calculator allows analysts to choose to always use simulation if desired.

Path Sets

Relyence RBD includes the ability to evaluate the Path Sets of your diagram. Path sets are the pathways through your diagram that result in a successful route from start node through to end node. Path sets are useful for evaluating the overall reliability of your system, areas where improvement may be necessary, and areas where redundancy may be helpful.

Cut Sets

A Cut Set is a group of system components that, upon failure, lead to an overall top-level system failure. Cut Sets can be calculated in Relyence RBD. Results from cut set calculations include the individual block names that make up each cut set with their availability, as well as the overall availability of the cut set. Cut set analysis provides insight into the most critical components in your system and helps target product improvement efforts.

Path Set and Cut Set Highlighting

The Relyence RBD Path Set and Cut Set Highlighter tools sequentially highlight each path or cut set on your RBDs. You can also select a specific path or cut set to highlight on the diagram. This handy tool enables you to easily view and sequence through the appropriate groups of components on your RBD.

While most metrics of your RBDs are presented in a table format, this graphical format of results is uniquely intuitive and helpful in providing a visual view of system performance. The ability to view component data directly on the graphical views offers a meaningful and advantageous way to interpret your path and cut set data. Because the information is much more easily explained and, therefore, understood, these visual views are very helpful for presentations or when working in a collaborative team environment.

Relyence RBD Results
The calculation results for Relyence RBD can be viewed in the results dialog, directly on the diagram, in reports, and graphically in the RBD Dashboard.
Results Viewing

Relyence RBD has a fully customizable and flexible report generator for viewing your analytical results. You can also generate a graphical report of your diagram. Both the analytical result outputs and graphical reports can be exported to a variety of formats if needed.

You can view your RBD metrics directly on your diagram. The basic set of results can be displayed with each component block on the diagram. In addition, you can bring up the Relyence RBD Results window, and then subsequently click through the components in your diagram to see the complete result set for each component.
