摘要
目的研究安全分析中数据与信息合成的方法．方法分析了安全分析中数据的种类与来源，讨论了运用于安全分析中信息与数据合成的三种基本理论：概率理论、证据理论和可能性理论的数学基础及其信息合成的规则．结果明确了三类方法的特点和相互关系，在实际的安全分析中以上信息合成方法还存在较大的局限性．结论概率理论、证据理论和可能性理论在安全分析的信息合成中的应用有待进一步深入研究，新的信息合成技术有待开发．
Aim\ To study the approach to combining data with information in safety analysis Methods\ The source and the type of data and information using in safety analysis were analyzed Mathematical base and information combination rules of three theories: probability theory, evidenced theory and possibility theory which have been applied in the field of safety analysis were discussed Results\ The properties and the relationships among the approaches were presented The above three approaches have obvious limitation in practical usage Conclusion\ Applications of the probability theory, evidence theory and possibility theory to combining information with data remain to be further studied, and the new technology for information combination need developing
