Hazard Rate Order Between Parallel Systems With Multiple Types of Scaled Components

Applied Stochastic Models in Business and Industry
This study delves into the comparison of two parallel systems, each composed of multiple component types following the scale models with a shared baseline distribution.

SOME RESULTS ON REVERSED HAZARD RATE ORDERING

Communications in Statistics - Theory and Methods, 2001
Recently, the reversed hazard rate (RHR) function, defined as the ratio of the density to the distribution function, has become a topic of interest having applications in actuarial sciences, forensic studies and similar other fields. Here we establish results with respect to RHR ordering between the exponentiated random variables.

Performance bounds for optimal sales mechanisms beyond the monotone hazard rate condition

Journal of Mathematical Economics, 2019
In mechanism design, Myerson’s classical regularity assumption is often too weak to imply quantitative results about the performance of sales mechanisms.

A note on hazard rates of order statistics

Communications in Statistics - Theory and Methods, 1988
Let Fk:m be the cumulative disribution function of the kth order statistic in a sample of size n from a distribution F(x) with density function f(x).The primary objective of this paper is to show that Fk+1mis IHR(increasing hazard rate) if Fkm(x)is IHH and that Fk-1:n(x)is DHR.(decreasing hazard rate) if Fkm(x) is DHR.

Resolving an open problem on the hazard rate ordering of p-spacings

Probability in the Engineering and Informational Sciences, 2022
AbstractLet $V_{(r,n,\tilde {m}_n,k)}^{(p)}$ and $W_{(r,n,\tilde {m}_n,k)}^{(p)}$ be the $p$-spacings of generalized order statistics based on absolutely continuous distribution functions $F$ and $G$, respectively. Imposing some conditions on $F$ and $G$ and assuming that $m_1=\cdots =m_{n-1}$, Hu and Zhuang (2006.

Estimation in a Model of Sequential Order Statistics with Ordered Hazard Rates

2015
As a generalization of order statistics from independent and identically distributed random variables, sequential order statistics (SOSs) may be applied as a model for ordered data, when assuming changes of underlying distributions immediately after the occurrences of ordered observations.

Component redundancy vs system redundancy in the hazard rate ordering

IEEE Transactions on Reliability, 1995
Design engineers are well aware of the stochastic result which says that (under the appropriate assumptions) redundancy at the component level is superior to redundancy at the system level. Given the importance of the hazard rate in reliability and life testing, we investigate to what extent this principle holds for the stronger stochastic ordering ...
