Synthetic Weighted Method of Failure Samples Allocation in Maintainability Test

In the maintainability demonstration and evaluation test, the failure samples allocation considers single influence factor, the allocation result is not too reasonable, it affected the accuracy of the maintainability demonstration and evaluation result. In order to solve the problem, the synthetic weighted method of failure samples allocation was proposed which considered the failure samples allocation influence factors synthetically. Firstly, on the basis of analyzing the influence factors, it defined the influence factor set of failure samples allocation, and cleared the synthetic weighted allocation algorithm; then, it determined the influence coefficient and the value of the influence factors; finally, a maintainability demonstration and evaluation test had been done on certain system. The test result showed, the method proposed in this article considered more influence.
