Abstract

Several approaches for estimating the shape and scale parameters of mixed failure mode data are discussed. It is assumed that the equipment has two failure modes, and that the failure distributions of the two failure modes can be described with Weibull functions. Maximum likelihood method is the most commonly used technique for analyzing failure data resulting from competing failure modes, acting on a machine or product. The method is used by the researchers to estimate the relationship between life and death, the life distribution at any stress with all acting modes and the life distribution that would result if certain failure modes are eliminated.
