| Popis: | 98 In reliability test, accelerate life test, a method to achieve the goal of reducing test period utilizes products degradated under higher working stress level faster then ones under normal working stress level. Step stress testing is a special kind of ALT in which the stress on each specimen is increased step-by-step over time. Complete data, which record all failure times and grouped data, which only include the numbers of failure items are part types of data in life test. In this thesis, assume each product of lifetime follows an exponential distribution under the step stress accelerate life test Type-I censoring with grouped data. The few data cause Statistical analysis is very difficult. Therefore utilizes the characteristic that the product under stress level promotes unceasingly to propose that the new solution, and compare with the way of researching and analysing in the past. Finally, provide the suitable analytical method and experimental norm to predict products of lifetime. Provides the basis of the tactics of products improved and maintained. |
