具有广义Gumbel分布的两部件系统故障率的某些性质
Some Hazard Rate Properties on Systems with Two Components Following Generalized Gumbel Distribution
摘要
Abstract
We consider systems with two components following a generalized Gumbel joint distribution and a same marginal distri-bution.We study the monotony of their hazard rate functions and gain the bounds of them.A sufficient condition of hazard rate func-tion on series system which has an upside-down bathtub shape (a bathtub shape)is found.It is shown that when component is in-creasing failure rate (IFR),so is parallel system.These results partially generalized some conclusions on Joo and Mi.关键词
