Abstract
Competing risks theory concerns the system of logical series structure consisted of
several causes of failure. Based on competing risks theory, we derive the likelihood
function of a combined of series and parallel structure using obtainable data such
as times to failure, causes of failure, functioning or failed states of the system
and its parts. A predictive model for the failure rate of each part is also built
up by using the derived likelihood function. When additional data are available,
it is shown that the failure rate can be updated by using the Bayesian approach.
