| Abstract: | Degradation data provide an effective method for reliability analysis of high reliability and long life products,which has more information about reliability than time to failure data.A review of theory and engineering application in degradation modeling area is presented.Firstly,the conception and development of degradation modeling are introduced.The relationship between degradation model and time to failure distribution is presented.Then the related researches on degradation modeling with and without stress factors are summarized.Finally,some problems in the area of degradation modeling are analyzed briefly,and the future research is also presented. |
