Inference for exponentiated Weibull distribution under constant stress partially accelerated life tests with multiple censored

Optimum Constant-stress Partially Accelerated Life Tests for the Truncated Logistic Distribution under Time Constraint

This paper presents an optimum design of constant-stress partially accelerated life test (PALT) plan in which each item runs either at use or accelerated condition and product life follows Truncated Logistic distribution truncated at point zero under type-I censoring. Truncated distributions arise when sample selection is not possible in some sub-region of sample space. The optimal sample propo...

Failure Process Modeling with Censored Data in Accelerated Life Tests

Manufacturers need to evaluate the reliability of their products in order to increase the customer satisfaction. Proper analysis of reliability also requires an effective study of the failure process of a product, especially its failure time. So, the Failure Process Modeling (FPM) plays a key role in the reliability analysis of the system that has been less focused on. This paper introduces a f...

Design and Analysis of Step Stress Accelerated Life Tests for Censored Data}

Life testing often is consuming a very long time for testing. Therefore, the engineers and statisticians are looking for some approaches to reduce the running time. There is a recommended method for reducing the time of failure, such that the stress level of the test units will increase, and then they will fail earlier than normal operating conditions. These approaches are called accelerated li...
