Uncertainty is lack of believable knowledge or information about (1) all relevant antecedent conditions;(2) all possible outcomes; and (3a) either universal laws (governing deterministic outcomes as the only physically possible ones) or (3b) probability laws (governing indeterministic/stochastic sets of outcomes).

Despite the fact that deterministic relationships are used in most compiterized models for engineering,the model outputs are indeterministic due to the uncertain and stochastic nature of the model inputs and parameters. All the uncertainty may contribute to the stochsticity of the input parameters of a corresponding model which, in turn, result in output uncertainty.
