Access-control policies can be stated more succinctly if they support both rules that grant access and rules that deny access, but this introduces the possibility that multiple rules will give conflicting conclusions for an access. In this paper, we compare a new conflict-resolution method, which uses first specificity and then deny precedence, to the conflictresolution method used by Windows N...

today’s world economy situation forces enterprise organizations toward more soft and flexible organization, management, and production processes. they need to explore the most suitable knowledge management (km) tool not only to identify gaps and overlaps but also to maintain and support innovation cross organizations. in this study, a multiple-experts-multiple-criteria decision making model is ...

Conflict resolution is an important part of many intelligent systems such as production systems, planning tools and cognitive architectures. For example, the ACT–R cognitive architectire [Anderson and Lebiere, 1998] uses a powerful conflict resolution theory that allowed for modelling many characteristics of human decision making. The results of more recent works, however, pointed to the need o...

Common object models select method implementations based on the class of the receiver. If an object belongs to several classes, more than one implementation is applicable for a method call. We present a conflict resolution strategy to get exactly one implementation per call. This is achieved by adding derived classes with method redefinitions.

We introduce a new method for solving systems of linear inequalities over the rationals—the conflict resolution method. The method successively refines an initial assignment with the help of newly derived constraints until either the assignment becomes a solution of the system or a trivially unsatisfiable constraint is derived. We show that this method is correct and terminating. Our experiment...
