Prediction Probe


State-of-the-Art Probabilistic Software to Improve Your Bottom Line

UNIPASS® provides businesses with the most precise prediction solutions possible. After decades of development, validation, and operation, UNIPASS® software brings innovative solutions to some of the world's top technology-driven organizations, including NASA, the U.S. Army, Boeing, and United Technologies, among many others. Indeed, UNIPASS® has earned the esteem of the United States Army as "Best-In-Class."

Delivered to the desktop through a familiar windows-based interface, with a simple menu-driven system that integrates easily into most current computations environments, UNIPASS® provides most likely outcomes, computes the probabilities necessary for quantitative risk assessment and system reliability evaluation, predicts the likelihood of extreme events, and identifies key process drivers including input variables and uncertainties. The information obtained may be used to develop measurements, improvements, monitoring and control plans in Six Sigma projects.

Numerous Sensitivity Measures to Better Provide Insight into the Process

The following sensitivity measurements are provided by UNIPASS®  6.0:

  • Sensitivity of limit-state function with respect to the random variables at the Most Probable Point (MPP) in both standard, normal and original space.
  • Sensitivity of failure probability and/or reliability index with respect to the random variables, mean, standard deviations, and distributions parameters
  • Dimensionless, mean and standard deviation-based scaled sensitivity of failure probability and/or reliability index with respect to random variables, mean and standard deviations


Four Easy Ways to Interface with Multiple Software Systems Simultaneously

The UNIPASS®  interface modules allow simultaneous communication with multiple software systems. While enhancing the capabilities of these software systems, UNIPASS®  minimizes the number of deterministic software runs needed to perform Probabilistic Analysis. Version 6.0 interface options include:

  • Generic Interface: This interface, without any coding, allows simultaneous integration with one or more commercial and/or in-house software systems with multiple standard input and output files.
  • Customized Interface: This interface allows simultaneous integration with one or more commercial and/or in-house software systems with multiple standard input and nonstandard output files.
  • System Command Interface: This interface provides a flexible and robust alternative to the Generic and Customized Interfaces to integrate with one or more commercial and/or in-house software systems with multiple, nonstandard, input and output files.
  • MSC/NASTRAN Interface: This interface provides for performing probabilistic finite element analysis using MSC/NASTRAN finite element code (interface with other finite element software may be established using other interface options)


Multiple Operating Systems to Quickly Integrate into Most Existing Environments

UNIPASS®  is easy to use and easy to integrate into most existing environments without a significant learning curve or additional hardware investment. Version 6.0 is compatible with Windows 95, 98, ME, NT, 2000, XP, and Vista. Furthermore, utilizing its UniFace module, UNIPASS®  6.0 can communicate with software systems residing on UNIX or others popular operating systems.
