Some New Proofs of Results on Hazard-Rate Functions
IEEE Transactions on Reliability, 1971Simple proofs are given for the properties of hazard-rate functions of systems, whose subsystems are operating sequentially (in series) or simultaneously (in parallel) and whose hazard-rate characteristics are known.

Statistical functions to represent various types of hazard rates
Microelectronics Reliability, 1980Abstract This paper presents two hazard rate models, I and II. Hazard rate and reliability expressions are presented. Model I parameters are estimated by applying the hazard plotting technique.

A unimodal hazard rate function and its failure distribution
Statistical Papers, 1992A unimodal hazard rate function is suggested to model a failure rate that has a relatively high rate of failure in the middle of expected life time. This unimodal hazard rate function has two shape parameters. One of the parameters indicates the location (time) of the mode and the other controls the height of the mode.

Nonparametric estimation of the hazard rate function and its derivative
Russian Physics Journal, 1999A class of nonparametric kernel estimates is suggested for an unknown hazard rate function and its derivative. Distribution and mean square convergences of the proposed estimates to the unknown hazard function and its derivative are proved. These estimates can be used for solving the problems of operational reliability of complex physical, technical ...

Bathtub-Shaped Hazard Rate Function for Ultra-thin Gate Dielectrics
ECS Transactions, 2007The hazard rate function for the time-dependent dielectric breakdown of gate dielectrics is reported in this study. Time-to-breakdown data are simulated from a lifetime distribution that considers the physical nature of the breakdown mechanisms. The bathtub-shaped hazard rate function is observed based on a simulation study.

MEAN RESIDUAL LIFE FUNCTION FOR ADDITIVE AND MULTIPLICATIVE HAZARD RATE MODELS
Probability in the Engineering and Informational Sciences, 2015This paper deals with the mean residual life function (MRLF) and its monotonicity in the case of additive and multiplicative hazard rate models. It is shown that additive (multiplicative) hazard rate does not imply reduced (proportional) MRLF and vice versa. Necessary and sufficient conditions are obtained for the two models to hold simultaneously.

A reliability comparison of basic systems using hazard rate functions
Applied Stochastic Models and Data Analysis, 1997Let us denote by \(F_{X}(t)\), \(\overline F_{X}(t)=1-F_{X}(t)\), \(f_{X}(t)\), respectively, the distribution function, the survival function and the density function of continuous random lifetime \(X\). The hazard rate function of \(X\) is defined by \(r_{X}(t)=f_{X}(t)/\overline F_{X}(t)\).
