| Abstract: | Given the accelerated equation of k-stress with l-unknown parameters,This paper slves the problem of the optimal designs of the accelerated life tests of type Ⅱ with competing causes of failure,whose life of each failure cause is assumed to be exponential.We obtain the optimum test designs according to D-optimal and V-optimal. |

| Keywords: | competing causes of failure asymptotic variance fisher information matrix optimal design D-optimal V-optimal. |
