If you can flowchart it, you can simulate it!TM

If you thought that building complex models for simulation or discrete analysis would require buying ridiculously expensive software and then writing code on top of that... we have good news for you!

ReliaSoft's RENO software is a powerful and user-friendly platform for analyzing any probabilistic or deterministic scenario using an intuitive flowchart modeling approach and discrete event simulation.

You can create flowchart models for complex reliability analysis, risk and safety analysis or maintenance planning.

RENO is a part of theSynthesis Platform®.

Sensitivity Analysis

  • Vary one or two constants across a set of simulation runs
  • Analyze how different inputs will affect the final results


  • Automatically vary one or two constants within a given range
  • Find the value(s) that minimize or maximize a specified result


  • Plot a result against 1 or 2 varied constants
  • Compare one result against another
  • Plot results against the cumulative probability of the values
  • Display results values in pie charts and bar charts

Real Power for Real Applications

You can use the flowchart models that you create with RENO to estimate results of interest, perform sensitivity analysis to evaluate how key inputs will affect the results and automatically estimate optimum values by performing multiple simulation runs.

These techniques can be applied for a wide variety of applications including, but not limited to:
