Release Updates

The release of ReliaSoft 2025 delivers improvements in functionality and performance for Weibull ++,  XFMEA, Lambda Predict and BlockSim, along with enhanced security across all ReliaSoft products.​ ​

This latest version focuses on customer-requested enhancements, performance improvements, and security updates to ensure more efficient, secure, and reliable data-driven analyses.​ 

Competing Risks Analysis​​ ​

New in Weibull++ 2025, the Competing Risks Weibull model provides a way to analyze data sets where more than one failure mode must be considered for every data point. ​​ ​

This method expands on previous functionality in the software and is more flexible with regard to the data requirements.​​ ​

The Competing Risks method is similar to the Mixed Weibull approach but can be easier to apply to real world data since the failure mode for each data point does not need to be specified by the user. ​​This means that users can more easily evaluate multimodal datasets with more confidence.
