针对传统的可靠性分析模型知识描述能力差和分析结果指导意义较弱的问题,设计一种功能模型用于可靠性分析.这种模型能够描述系统功能知识和性能知识,并且能够建立系统性能对功能的影响关系.此模型的建模过程较为简捷,模型结构适合于可靠性推理.由于模型描述了系统本身的领域知识,基于该模型得到的可靠性分析结果较传统的可靠性分析结果更具指导意义.最后,基于这种建模策略建立了某型家用门铃系统的功能模型,并分析了其可靠性,验证了该模型及其算法的有效性.
Aiming at the problem that the traditional reliability analysis model has poor knowledge description ability and weak guidance of the analysis results, a functional model is designed for the reliability analysis, which can describe the system functional knowledge and performance knowledge and establish the system performance pairs Function of the relationship between the model of the modeling process is relatively simple and the model structure is suitable for reliability reasoning.As the model describes the domain knowledge of the system itself based on the model reliability analysis results obtained more than the traditional reliability analysis results more It is instructive to use it.Finally, based on this modeling strategy, a functional model of a home doorbell system is established and its reliability is analyzed. The validity of the model and its algorithm is verified.
