摘要：

We introduce a new finite range life distribution with a hazard rate function of the form of a nonstandard beta density function. The hazard rate function is either increasing, or has a bathtub shape with a long flat middle interval. The proposed model has a simple structure. Several datasets from the reliability literature with known bathtub shaped hazards were successfully fitted to this distribution.
