Arguing for Decisions: A Qualitative Model of Decision Making
  We develop a qualitative model of decision making with two aims: to describe
how people make simple decisions and to enable computer programs to do the
same. Current approaches based on Planning or Decisions Theory either ignore
uncertainty and tradeoffs, or provide languages and algorithms that are too
complex for this task. The proposed model provides a language based on rules, a
semantics based on high probabilities and lexicographical preferences, and a
transparent decision procedure where reasons for and against decisions
interact. The model is no substitude for Decision Theory, yet for decisions
that people find easy to explain it may provide an appealing alternative.
