摘要：
The theory of evidence and the theory of possibility have been suggested as possible alternatives to probability theory in safety analyses of engineering systems. This paper discusses three issues: (1) how formal probability theory has been relaxed to develop these nonprobabilistic models; (2) how degrees of belief are expressed in probabilistic and nonprobabilistic theories; and (3) the degree to which these nonprobabilistic models can be applied to system analysis in terms of their capability to combine knowledge. © 1990.
