چکیده
This paper introduces the idea of using the Dempster-Shafer theory of evidence with qualitative values. Dempster-Shafer theory is a formalism for reasoning under uncertainty which may be viewed as a generalisation of probability theory with special advantages in its treatment of ambiguous data and the ignorance arising from it. Here we are interested in applying the theory when the numbers that it usually operates over are not universally available. To cope with this lack of numbers, we use qualitative, linguistic and relative values.

متن کاملProject Risk Assessment Framework
This study presents a framework for calculating the risk of various projects, especially projects under uncertain circumstances. First, the related literature is reviewed and then the relationship between risk and projects is examined. Using a case study an approach is provided to determine the project risk in uncertain circumstances where sufficient data is not available for decision-making. I...

متن کاملOn reasoning in networks with qualitative uncertainty
In this paper some initial work towards a new approach to qualitative reasoning under un certainty is presented. This method is not only applicable to qualitative probabilistic reasoning, as is the case with other methods, but also allows the qualitative propagation within networks of values based upon possi bility theory and Dempster-Shafer evidence theory. The method is applied to two simpl...
