A product usually consists of multiple components. Product design needs to specify the life limit of each component. The life limit can be viewed as a preventive replacement age and expressed as a B X life. A large value of X means low cycle reliability but small life loss. As such, X must be appropriately specified so that a good tradeoff between reliability and life can be achieved. This...
This paper deals with the problem of determining the maximum service life (or BX life) of a component, whose life follows a normal distribution. The problem is equivalent to determining the value of X of the BX life. A heuristic method is used to find the change point of the failure rate, which depends on the coefficient of variation and is smaller than the left inflection point of the pdf. It appears...
