Risk Analysis Virtual Environment

RAVEN is designed to perform parametric and probabilistic analysis based on the response of complex system codes. RAVEN is capable of investigating the system response as well as the input space using Monte Carlo, Grid, or Latin Hyper Cube sampling schemes, but its strength is focused toward system feature discovery, such as limit surfaces, separating regions of the input space leading to system failure, using dynamic supervised learning techniques. RAVEN includes the following major capabilities:

The RAVEN statistical analysis framework can be employed for several types of applications:

RAVEN provides a set of basic and advanced capabilities that ranges from data generation, data processing and data visualization.

Computing environment

Forward propagation of uncertainties

Advance sampling methods

Creation and use of reduced order models

Model capabilities

Data Post-Processing capabilities

Model parameter optimization

Data management
