When products start failing, management wants answers. Are they failing because of manufacturing problems? Or is the design to blame? One of the most widely regarded methods for ferreting out the ...

This paper presents, in a case study format, a methodology for combining the methods of Design of Experiments, Accelerated Testing, and Weibull Analysis to improve the reliability of an ABS ...

Exponentiated Weibull distribution, introduced as an extension of the Weibull distribution, is characterized by bathtub shaped, unimodal failure rates besides a broader class of monotone failure rates ...

A Weibull reliability analysis of a repeated pump problem at Chevron Corp.'s Pascagoula, Miss., refinery helped the company identify the failure mode and improve reliability. Rather than accepting the ...

Table 30.1 shows the time in months of each inspection period and the number of cracked parts found in each period. These data are said to be interval censored since only the time interval in which ...

Here’s a way to calculate the reliability for designs with several subsystems. • Weibull plots fit a curve through data, not data to a predetermined distribution’s curve. • After evaluating subsystems ...

Due to widespread improvements in the manufacturing and testing of tantalum capacitors, AVX’s new Q-Process hopes to replace the Weibull Reliability Assessment as the industry standard. The process ...

Light emitting diodes (LEDs) have emerged as a cornerstone of modern lighting technologies, and ensuring their reliability and optimal performance is both a technical and economic imperative. Recent ...
