We, in this paper, establish a functional inspection model（ FIM） the cost model and the availability model for the immeasurable potential failure state based on the delay time concept. This model can be used to determine the appropriate Functional Inspection Interval（FII） to achieve the goal of specific cost and availability and to assist in maintenance decision making.展开更多

On the basis of above research,a numerical example was given to illustrate the engineering application and generality of the warranty reliability model.展开更多

The intervals of the plant from new to when the potential failure and from potential failure to functional failure are regarded, in this paper, as a random variables. Numerical examples indicate both the nature and sensitivity of the output from the models.展开更多
