Abstract

Generally, most Decision Systems do not consider the uncertainty that might be present in knowledge. On many occasions, this leads to proposed solutions that are sometimes inconsistent with the expected results. Case-Based Reasoning is one of the techniques of Artificial Intelligence used in the solution of decision-making problems. Consequently, Case-Based Systems, must consider imperfection in the available knowledge about the world. In this paper, we present a model to make case-based decisions under uncertainty conditions. The model uses Decision Trees and Rough Set Theory to assure an efficient access and an adequate retrieval of cases.
