The theory of interval-probability as a unifying concept for uncertainty

The concept of interval-probability is motivated by the goal to generalize classical probability so that it can be used for describing uncertainty in general. The foundations of the theory are based on a system of three axioms - in addition to Kolmogorov's axioms - and definitions of independence as well as of conditional-probability. The resulting theory does not depend upon interpretations of the probability concept. As an example of generalising classical results Bayes' theorem is described - other theorems are only mentioned.
