Failure rate is a commonly used reliability measure for engineering systems. Accurately describing failure rate of a system often plays a crucial role in maintainability analysis and modeling. The failure dependency among components will accelerate the failure process of entire system. This paper proposes a new failure rate model with considering the failure interaction between components. Examples...
Reliability is one of the critical attributes for long life and high performance satellite. To deal with the limitation on satellite reliability analysis confronted in the past decades, a series of papers has been published recently by Saleh et al. In these papers, thousands of Earth-orbiting satellites successfully launched between 1990 and 2008 have been analyzed. This paper extends the statistical...
The bathtub-shaped curve is essential in interpreting the failure rate function for the reliability analysis, and its parameters determine the representation of the bathtub-shaped function. This paper introduces a parameterised bathtub curve that provides an adaptive bathtub-shaped failure rate function (ABF) modelling approach which can be also easily utilised as a universal objective for further...
Many mechanical components exhibit more than one failure mode; and not all components under study have been exposed to similar operating conditions. For example, components may have been used in different operating environments or there may be differences in design and/or material. In these cases, life time data of components would not fall on a straight line on a Weibull probability paper (WPP),...
