Definition of optimal accelerated test plan
Résumé
The objective of this paper is to define an optimal accelerated test plan considering an economic approach. The objective function is defined by two terms: the cost linked to testing activities and the cost associated to operation of the product. The optimal test plans are defined in considering a prior knowledge on reliability parameters (choice of reliability function, scale and shape parameters …) and acceleration model (choice of model, model parameters …) to characterize the accelerated life model. This information is used in Bayesian inference (to optimize the testing plan). The prior knowledge contains also the uncertainty on real reliability of new product. So, the developed methodology proposes to define an optimal accelerated testing plan in considering an objective function based on economic approach, Bayesian inference for optimizing the test plan and taking into account the uncertainty on parameters to obtain a robust optimal test plan.
