| Abstract: | Degradation reliability prediction under stochastic failure threshold was studied. The explicit expression of reli.ability was derived, by charactering the uncertainty of failure threshold with probability distribution. Then, a possibilisticmethod for reliability modeling and prediction for degrading components was presented, by use of possibility distribution. |

| Keywords: | degradation models stochastic failure threshold uncertainty possibilistic method |
