A Belief-Function Based Decision Support System

In this paper, we present a decision support system based on belief functions and the pignistic transformation. The system is an integration of an evidential system for belief function propagation and a valuation-based system for Bayesian decision analysis. The two subsystems are connected through the pignistic transformation. The system takes as inputs the user's "gut feelings" about a situati...

Decision Making: A Cognitive Function Approach

This paper presents a cognitive function approach to decision-making. Traditional approaches are usually based on single-agent models that typically attempt to capture sequential information processing. They are limited to the account of cognitive functions such as observation, interpretation, planning and action execution. Multi-agent models enable the capture of both sequential and parallel i...

The lexicographic decision function

In this paper the lexicographic decision process is presented in a unified way. We construct a lexicographic decision function using a universal preference function and a unary function. This construction incorporates the different outranking approaches,the lexicographic decision process and the utility based decision making models. Finally we consider the connection of the lexicographic decisi...

A decision procedure for the existence of a rank function

Schneider’s work on rank functions [17] provides a formal approach to verification of certain properties of a security protocol. However, he illustrates the approach only with a protocol running on a small network; and no help is given with the somewhat hit-and-miss process of finding the rank function that underpins the central theorem. In this paper, we develop the theory to allow for an arbi...
