BDI and QDT: A Comparison Based on Classical Decision Theory

In this paper we compare Beliefs-Desire-Intention systems (BDI systems) with Qualitative Decision Theory (QDT). Our analysis based on classical decision theory illustrates several issues where one area may profit from research in the other area. BDI has studied how intentions link subsequent decisions, whereas QDT has studied methods to calculate candidate goals from desires, and how to derive intentions from goals. We also discuss the role of goals and norms in both approaches.
