Managing local fuzzy logics in MILORD-II

MILORD is a working expert system shell oriented to classification tasks. The authors describe a modular extension of the MILORD system. This modular extension, called MILORD-II, addresses two main characteristics of human problem solving: the application of general knowledge to particular problems, and the dependence of the kind of management of uncertainty on the particular subtasks. The focus is on the two important roles uncertainty plays in this modular system: (i) as part of local deductive mechanisms, and (ii) as a control feature in the process of selecting and combining knowledge base units or modules
