学术报告题目：Some extended Weibull distribution for the modelling bathtub shaped failure rate in reliability engineering
学术报告摘要：Exponential distribution is widely used in the modelling and analysis of time-between-events, particularly in reliability engineering. It is well-known that this distribution implies no-ageing which is not realistic. Weibull distribution can be used for increasing failure rate or decreasing failure rate. It is especially suitable for industrial applications because of its graphical interpretation and probability plotting procedure for both parameter estimation and model validation. However, the basic Weibull distribution with two parameters cannot be used for the well-known bathtub-shaped failure rate function. Several extended Weibull distributions have been developed and studied. In this talk, we will introduce some of our research works in this area. Some useful models will be presented and their properties and uses will be discussed. A few related research directions will also be highlighted.
