reactorpump: Failure Time Intervals of Secondary Reactor Pumps

Description

This dataset contains the time intervals between failures (in thousands of hours) of secondary reactor pumps. The data were reported by Salman Suprawhardana, Prayoto, and Sangadji (1999) and later analyzed in Bebbington, Lai, and Zitikis (2007) in the context of flexible Weibull extensions.

Usage

reactorpump

Value

An object of class "numeric".

The vector consists of 23 observed time intervals between successive failures of secondary reactor pumps, measured in thousands of operating hours. Each value represents the elapsed time between two consecutive failure events for a pump component. The dataset is commonly used in reliability engineering and survival analysis for modeling lifetime distributions, studying hazard rate shapes, and evaluating the flexibility of parametric failure-time models.

Format

A numeric vector of length 23 containing time intervals between pump failures, measured in thousands of hours.

Details

These data are commonly used in the reliability engineering literature, particularly for assessing lifetime distributions, hazard shapes, and model flexibility in mechanical systems. The pump failure times originate from components of the RSG-GAS reactor.
