New Flexible Weibull Distribution

Abstract

In the present paper, a new function is suggested to develop a new lifetime model. The new model is proposed by considering the linear scheme of the two logarithms of cumulative hazard functions. The proposed model is known as New Flexible Weibull distribution, capable of modeling data with increasing or bathtub shaped failure rates and offers a greater distribution flexibility. Therefore, it can be useful to use an alternative model to many other ageing distributions, where, data modeling with increasing or bathtub shaped failure rates are of interest. A brief mathematical explanation for the reliability function is provided. The parameters of the proposed model are estimated by using the maximum likelihood method. To claim the workability of the proposed model, two illustrated examples are provided.
