The Weibull distribution remains an indispensable tool in reliability engineering and lifetime analysis, offering flexibility for modelling diverse failure behaviours. Modern parameter estimation ...

今回も品質管理に関する記事を記載いたします。 はじめに ワイブル分布（Weibull distribution）は、寿命データや故障時間を扱う分野で最も広く使われている分布の一つです。部品や機械の寿命、材料の強度にも応用されます。 本記事では、下記について ...

Abstract: The time to electric breakdown, and the electric field necessary to result in breakdown of solid insulation, seem to be best represented by a Weibull probability distribution. This tutorial ...

The following data are taken from Lawless (1982, p.193) and represent the number of days it took rats painted with a carcinogen to develop carcinoma. The last 2 observations are censored data from a ...

Maximum likelihood estimation of the parameters of a statistical model involves maximizing the likelihood or, equivalently, the log likelihood with respect to the parameters. The parameter values at ...

Abstract: In modern refinery and chemical production, equipment is the lifeblood and foundation of enterprise safety production. The reliability analysis of the rotating equipment is aimed at the ...
