Analysis of Bivariate Accelerated Life Test Data for the Bivariate Exponential Distribution

SYNOPTIC ABSTRACT

Accelerated life testing of a product is commonly used to reduce test time and costs. Accelerated testing is achieved by subjecting the test units to conditions that are more severe than the typical ones. The results obtained at the more severe conditions are then extrapolated to typical conditions to obtain an estimate of life distribution under typical conditions. This problem is considered when the product is a 2-component system with the bivariate exponential distribution of Marshall and Olkin (1967); our interest is the joint analysis of data with two failure times.

Key Words and Phrases:

• bivariate exponential distribution
• power rule model
• acceletated life tests
