Accelerated Destructive Degradation Test Planning
Accelerated Destructive Degradation Tests (ADDTs) provide reliability information quickly. An ADDT plan specifies factor level combinations of an accelerating variable (e.g., temperature) and evaluation time and the allocations of test units to these combinations. This paper describes methods to find good ADDT plans for an important class of destructive degradation models. First, a collection o...
متن کاملPlanning Accelerated Destructive Degradation Test with Competing Risks
Accelerated destructive degradation tests (ADDTs) are widely used in manufacturing industries to obtain timely product reliability information, especially in applications where few or no failures are expected under use conditions in tests of practical length. An ADDT plan specifies the test conditions of accelerating variables, running time, and the corresponding allocation of test units to eac...
متن کاملAccelerated Test Planning with Independent Competing Risks and Concave Degradation Path
Abstract: A step-stress test in the presence of competing risks and using degradation measurements is considered. It is assumed that underlying degradation path follows a concave degradation model and the intensity functions corresponding to competing risks depend only on the level of degradation. In this work, information from step-stress test at high level of stress is extrapolated, through a...
متن کاملMethods For Planning Accelerated Repeated Measures Degradation Tests
Accelerated repeated measures degradation tests can sometimes be used to assess product or component reliability when one would expect few or even no failures during a study. Such tests can be used to estimate the lifetime distributions of highly reliable items. This paper describes methods for selecting a single-variable accelerated repeated measures degradation test plan when the (possibly tr...
متن کاملOptimal step-stress accelerated degradation test plan for Gamma process
Step-stress accelerated degradation test (SSADT) is a useful tool for assessing the lifetime distribution of highly reliable products (under a normal-use condition) when the available test items are very few. Recently, an optimal SSADT plan has been proposed in the literature which is based on the assumption that the underlying degradation path follows a Wiener process. However, the degradation...
