It employes powerful Bayesian techniques on an easy-to-use software platform. Reliability data generated in R-DAT can be imported to reliability parameters in RiskSpectrum PSA.  RiskSpectrum AB and [Prediction Technologies Inc](https://www.prediction-technologies.com/rdat). (the developer of R-DAT) have a long history of co-operation.  Use R-DAT To: - Store and Organize Raw System-Specific Data - Store and Organize Generic Raw Data - Develop System-Specific Reliability Parameters (e.g., Failure Rate Distributions) - Develop Generic Distributions - Understand and Interpret Results Using Powerful Graphical Displays ![](https://www.riskspectrum.com/hs-fs/hubfs/image-png-Jun-26-2024-08-58-27-4417-AM.png?width=1283&height=805&name=image-png-Jun-26-2024-08-58-27-4417-AM.png)   ## Software In Action   - Calculating Failure Rate Distribution - Export to RiskSpectrum PSA #### Developing System Specific Failure Rate Distribution - Select prior distribution type - Select prior input mode - Specify the prior parameters - Specify system-specific data - Perform Bayesian updating ![](https://www.riskspectrum.com/hs-fs/hubfs/image-png-Jun-26-2024-09-08-12-1536-AM.png?width=1063&height=805&name=image-png-Jun-26-2024-09-08-12-1536-AM.png) #### Export results to RiskSpectrum PSA - Data exporting at Project/Sub System/Item Level - Excel format supported at all levels - A user friendly feature to allow RDAT analysis results to be exported into excel format required by RiskSpectrum PSA ![](https://www.riskspectrum.com/hs-fs/hubfs/image-png-Jun-26-2024-09-41-11-2726-AM.png?width=1425&height=805&name=image-png-Jun-26-2024-09-41-11-2726-AM.png) ![riskspectrum white logo](https://www.riskspectrum.com/hs-fs/hubfs/riskspectrum%20white%20logo.png?width=150&height=71&name=riskspectrum%20white%20logo.png)   ##### Software Software - [RiskSpectrum PSA](https://www.riskspectrum.com/riskspectrum-psa) - [RiskSpectrum PSA Macro](https://www.riskspectrum.com/riskspectrum-psa-macro) - [RiskSpectrum ModelBuilder](https://www.riskspectrum.com/riskspectrum-modelbuilder) - [RiskSpectrum HRA](https://www.riskspectrum.com/riskspectrum-hra) - [RiskSpectrum RiskWatcher](https://www.riskspectrum.com/riskspectrum-riskwatcher) - [RiskSpectrum SDP](https://www.riskspectrum.com/riskspectrum-sdp) - [RiskSpectrum I&AB](https://www.riskspectrum.com/riskspectrum-iab) - [R-DAT](https://www.riskspectrum.com/r-dat) ##### Solutions Solutions - [Probabilistic Safety Assessment (PSA)](https://www.riskspectrum.com/probabilistic-safety-assessment-psa) - [Reliability & Availability Assessment](https://www.riskspectrum.com/risk-reliability-and-availability-analysis) ##### Resources Resources - [Downloads & Resources](https://www.riskspectrum.com/downloads-resources) - [Training](https://www.riskspectrum.com/training) - [Contact Us](https://www.riskspectrum.com/contact) - [Privacy Policy](https://www.riskspectrum.com/privacy-policy) © 2026 RiskSpectrum Return to top
