Qualitative Approaches,d for reasoning is to add new beliefs to the current set of beliefs. In such a monotonic approach, common-sense reasoning, the frame problem, and the control problem, three problems studied by M. Minsky, J. McCarthy, and others (Doyle, 1979), cannot be resolved

Two-Valued Quantitative Approaches,ory or evidence theory, appeared in the seventeenth century, in works of G. Hooper and J. Bernoulli. The INERNO system was introduced in Quinlan (1983b). A number of systems, reasoning under uncertainty using the Dempster-Shafer theory, have been implemented, for example, Lowrance .. (1986), Biswas and Anand (1987), Zarley .. (1988).

Set-Valued Quantitative Approaches,ch may also be viewed as a fuzzy set. An incidence from incidence calculus is a set, a subset of the set of discourse. Finally, a rough set characterizes uncertainty by a family of subsets of the universe
