Selection of Acceleration Models for Test Planning and Model Usage

Acceleration models have a high potential to save resources, such as time and money within the reliability determination by tests. A high number of acceleration models are available in the literature, for that reason it is difficult to select an adequate model for special cases. This paper provides an overview of the large number of available acceleration models for the most common failure mechanisms in literature, as well as a methodical approach for their selection by considering the occurring operation conditions and the failure mechanism within the system structure. Furthermore, a way to determine the necessary product-specific model parameters is shown, together with a list of literature values and their references. Some information for the usage of acceleration models within a system consideration is given, as well.
