Dynamic fault tree analysis is widely used for the reliability analysis of the complex system with dynamic failure characteristics. In many circumstances, the exact value of system reliability is difficult to obtain due to absent or insufficient data for failure probabilities or failure rates of components. The traditional fuzzy operation arithmetic based on extension principle or interval theory...
In the storage reliability evaluation, storage equipment is typically evaluated by stored data or accelerated test data. But the effect of component degradation on system degradation is not considered in depth. A storage reliability evaluation method based on probability density evolution is proposed from the point of view of the component in this paper. This method does not need to discretize the...
For the purpose of assessing the accelerated degradation failure time distribution of product, a kind of method to extend extremely small sample for large sample is put forward in this paper. This method divides the original degradation test data into sections and randomly selects partial data from each piece of data. Then, the sampled data form a new test sample. Through this method the sample size...
