Abstract
En 中文
This paper is the second in the series of three addressing the problem of how to deal with uncertainties in the modelings of engineering problems using only available data. The problem of the heat exchanger was selected as the example because it is sufficiently complex but still simple so that the difficulties and ideas will be apparent. There are various theories on how to treat the uncertainties in the first paper. In the series we use only the fuzzy set, respectively the possibility theory. In this paper we use the fuzzy approach for some model parameters and the probability approach for the others. The third paper will use the Bayesian theory. (C) 2013 Elsevier B.V.
