Conquering the challenge of reliability: text mining to map trends in reliability engineering literature
Reliability engineering faces many of the same challenges in 2023 that it did at its inception in the 1950s. The fundamental issue remains uncertainty in system representation, specifically related to performance model structure and parametrization. Details of a design are unavailable early in the …

Bayesian Inference of the Weibull-Pareto Distribution
… Some of these topics include survival analysis, reliability engineering, general insurance, electrical engineering, and industrial engineering. The Weibull distribution was further extended by the Weibull-Pareto distribution. A desirable property this distribution has is its shape can skew being …
