General outlook of UNIPASS¿ V5.0: A general-purpose probabilistic software system

Abstract This paper briefly describes many features, options and capabilities of UNIfied Probabilistic Assessment Software System, UNIPASS™ Version 5.0. This software is a PC-based Windows 32 compliant software engine that can be utilized independently, as a stand-alone tool, or integrated with deterministic software tools to perform complex probabilistic analysis. In the analysis, UNIPASS™ provides the basis for modeling uncertainties, defining variable probability distribution and probabilistic response models, computing probabilities, identifying most likely outcomes, and providing sensitivity measures, while the deterministic software tools may be integrated to provide the computational framework for constructing complex deterministic models. Combining a familiar Windows-based interface with a simple menu-driven system, UNIPASS™ integrates easily into most existing environments without a significant learning curve or additional hardware investment.
