| Abstract: |
| Objective To study the question of parameter estimation for missile accelerated storage life tests. Methods A series of repeated and continuous accelerated simulation tests for missile storage life were designed with insufficient data. The results of previous test was taken as prior distribution of the next test. An accelerated storage life model of missile was established based on Bayes method to propose the algorithm of estimation of storage life parameters and discuss methods for reliability assessment of missile storage. Results The example provided the maximum likelihood estimation of parameters. The value of estimation was adjusted with RBA method and the storage reliability of missile was proposed. The mean square errors of the new estimation are less. Conclusion Bayes algorithm of sequence tests is simple and precise, which will be applicable to evaluation of missile storage reliability. |
