In view of the complexity and uncertainty of system, both the state performances and state probabilities
of multi-state components can be expressed by interval numbers. The belief function theory is used to
characterize the uncertainty caused by various factors. A modified Markov model is proposed to obtain the state
probabilities of components at any given moment and subsequently the mass function is used to represent the
precise belief degree of state probabilities. Based on the primary studies of universal generating function (UGF)
method, a belief UGF (BUGF) method is utilized to analyze the reliability and the uncertainty of excavator rectifier
feedback system. This paper provides an available method to evaluate the reliability of multi-state systems
(MSSs) with interval state performances and state probabilities, and also avoid the interval expansion problem.
