大型集成概率安全分析软件系统的研究与发展

Development of an integrated probabilistic safety assessment program

FDS团队在广泛调研和深入分析国际现有概率安全分析软件及其关键技术的基础上,研发了具有自主知识产权的大型概率安全分析软件系统RiskA。该软件提供了系统建模、故障树分析、事件树分析、不确定性分析、可靠性数据管理与分析、敏感性分析和重要度分析等概率安全分析所需的基本功能。介绍RiskA的设计思想、总体结构、主要功能、技术特点和相关测试与应用等。

An integrated Probabilistic Safety Assessment （PSA） program named RiskA has been developed, which can be applied to Fault Tree Analysis, Event Tree Analysis, Uncertainty Analysis, Sensitivity Analysis, Importance Analysis, Reliability Data Analysis and Management. An overview of the architecture and functions of RiskA is presented in this paper, as well as the testing and application. The algorithms for Fault Tree Analysis, Event Tree Analysis and Uncertainty Analysis are also presented.
