Abstract

For some products that degrade over time, failure is defined in terms of a specified critical value of performance characteristic. The life of such a product depends on the specified critical value. The more severe the critical value, the shorter the life would be, and vice versa. This paper presents a method of accelerating life by using severe critical values. The method, based on degradation measurements, provides estimates of the relationship between life and critical value and reliability. An example is given to illustrate the application of the proposed method. Comparison between the method and traditional time-to-failure analysis shows that the proposed method is more efficient and cost-effective.
