The maintenance service policy plays a main role to assist any manufacturing organization for safe and available its equipment's and maintenance cost effective. Therefore, we need to estimate the costs of maintenance service policy. The partially step -stress accelerated life test is assumed when the lifetime of test units follows an extension of exponential distribution. Based on Type II censo...

Constant-stress procedure based on parametric lifetime distribution and model is often used for accelerated life testing in product reliability experiment. Maximum likelihood estimation is the typically statistical inference method. This paper presents a new inference method, named random variable transformation (RVT) method for Weibull constant-stress accelerated life test with progressively T...

A collaboration between the developer of a Removable Hard Disk Drive (RHDD) storage technology product and academics presents an accelerated life test of non-spinning powered down hard disks. The results are used to predict the reliability of removable disk cartridges stored in shirtsleeve environments as archival media. The contributions of this paper include an initial study of the reliabilit...

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...
