Accelerated life tests are used to explore the lifetime of extremely reliable items by subjecting them elevated stress levels from stressors cause early failures, such as temperature, voltage, pressure, and so on. The alpha power inverse Weibull (APIW) distribution is great significance practical applications due its appealing characteristics, flexibilities in probability density function hazar...

Over the years, several researchers have worked to model phenomena in which distribution of data presents more or less heavy tails. With this aim, generalizations extensions Lomax been proposed. In paper, an attempt is made create a hybrid mixing functionalities Nadarajah–Haghighi and distributions, namely (NHLx) distribution. It can also be thought as extension exponential The NHLx has feature...

In survival analysis or reliability and maintenance studies, hazard-rate function plays an important role, since it describes the instantaneous failure probability given that the individual survived or the item has not failed up to that instance. Sudden changes in the hazard function may occur due to overhauls, treatment effects or maintenance activities. A problem of statistical interest is th...

Sequential order statistics can be used to describe the lifetime of a system with n components which works as long as k components function assuming that failures possibly affect the lifetimes of remaining units. In this work, the reversed hazard rates of sequential order statistics are examined. Conditions for the reversed hazard rate ordering and the decreasing reversed hazard rate property o...

This paper presents an analysis of an electro-optical hazard alerting system based on intruder line-of-sight rate. We use a recently-developed airspace encounter model to analyze intruder line-of-sight rate behavior prior to near miss. We look at a simple hazard alerting system that alerts whenever the line-of-sight rate drops below some set threshold. Simulations demonstrate that such an appro...

Multivariate Decomposition for Hazard Rate Models We develop a regression decomposition technique for hazard rate models, where the difference in observed rates is decomposed into components attributable to group differences in characteristics and group differences in effects. The baseline hazard is specified using a piecewise constant exponential model, which leads to convenient estimation bas...
