摘　　要：可信性是系统的内在属性,也是评估系统质量的一项重要指标。系统可信性在其生命周期的不同阶段受到不同因素的影响,必须适当地加以管理,采用生命周期方法来获得可信性是实现可信性的关键。在现有的产品、数据、系统等生命周期模型的基础上,构建了系统可信性生命周期模型,包括概念、开发、实现、使用和退役/重用等5个生命周期阶段,并给出了各阶段应开展的可信性活动。通过系统生命周期各阶段可信性活动的实施,可促进系统可信性的实现,进行可信性价值创造。Dependability is an intrinsic attribute of a system and an important index to evaluate the quality of the system.The dependability of a system is affected by different factors in different stages of its life cycle,and it must be properly managed.The key to achieve dependability is to adopt a life-cycle approach to obtain dependability.Based on the existing life cycle models of products,data and systems,the system dependability life cycle model is constructed,including five life cycle stages of concept,development,realization,utilization and retire⁃ment/re-use,and the dependability activities to be carried out in each stage are given.The implementation of dependability activities in each phase of the system life cycle can promote the real⁃ization of system dependability and create dependability value.
