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 ...

This example illustrates probability plotting and distribution fitting for data grouped by the levels of a special group-variable. The data are from an accelerated life test of an insulating fluid and ...

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 ...

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 ...

This paper addresses a common problem associated with data analysis when a 1st failure in n, Weibull analysis is used. This is known among Weibull practitioners as the method of "sudden death".

Most products are built to specifications that include some measure of reliability. In the design stage, FEA does a good job of pinpointing the weak spots in parts and assemblies. But the real test ...

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 ...
