Random sets and fuzzy interval analysis. (English) Zbl 0734.65041

A random set is a convex combination of sets, and it is claimed that it is better than interval analysis for dealing with uncertain numerical data. A general framework for calculation under uncertainty is described in terms of random sets, via the generalization of a so-called extension principle, and then one considers calculation with random set valued operands.
