Chapter 7: Designing Accelerated Life Testing For Product Reliability Under Warranty Prospective

The modules of the difference between the true value of the parameter and its estimator converges to zero, hence consistent. whenever a product is tested for a long period of time, its reliability decreases because of the wear out in the product. The studies show that the preventive replacement will be strongly affected under PRRW. Particularly, when the product is proven to failures, and adding the PRRW will extend the optimal replacement age closer to the warranty period.
