Abstract:

In this article, we describe an abductive representation of decision problems under uncertainty based on ATMS. Firstly, we extend the ATMS framework so as to include, in addition to the usual assumption symbols, preference and decision symbols. Then we show how this framework can be further extended, by allowing to assign multiple (real or qualitative) values to assumption and preference symbols, for modeling gradual uncertainty and preferences, respectively. Two extensions are described, agreeing respectively with two non-classical decision theories.
