ABSTRACT = {Existing non-monotonic formalisms are generally designed to capture a
single criterion for determining preference among competing models. As 
pointed out by Jon Doyle, one must aggregate individual preference
orders into a global order to obtain unified non-monotonic formalisms.
As long as one considers preference modeling in terms of classical
decision theory, any attempt at aggregating different criteria will 
violate certain commonsense postulates about preference orderings.

Fortunately, recent advances in multiple-criteria decision theory permit
the use of preference orderings not limited by the classical constraints
of complete comparability and transitivity. The advantage is that one
is able to model decision scenarios where information is incomplete and
inconsistent. In addition, non-conventional preference modeling may provide
a potential solution to the aggregation problem discussed by Doyle. One
obstacle towards applying non-conventional preference modeling has been the
lack of a sufficient axiomatization for non-conventional preference
structures. The main contribution of this paper is to propose the use
of a multi-valued para-consistent logic, WL4, as a means of providing a robust
semantic theory for non-conventional preference modeling.
