| 摘 要： | 提出了一种基于区间模糊集和证据推理方法的评估化工警报系统可靠性的新方法。在这种方法中 ,化工警报系统中各组成部分及部件的可靠性用区间模糊语言变量来表示 ,利用证据推理方法合成各子系统部件的可靠性评估结果 ,提高了各子系统的可靠性水平。文中以某工厂化工警报系统的可靠性评估阐述了该方法的应用情况。

| Abstract: | A new method for reliability evalution of the chemical engineering warning message system by using interval fuzzy sets and evidential reasoning was presented.In this methodology, the reliability of components of the subsystems in the chemical engineering warning message system were described by interval fuzzy linguistic variables. An evidential reasoning approach was employed to synthesize the reliability information of the components of each subsystem, further the reliability of the whole chemical engineering warning message system was got. Finally the reliability evaluation of the system using in a chemical plant was presented to demonstrate the proposed new methodology. |
