Defeasible logic is a nonmonotonic reasoning approach based on rules and priorities. Its design supports efficient implementation, and it shows promise to be successfully deployed in applications. So far only static priorities have been used, provided by an external superiority relation. In this paper we show how dynamic priorities can be integrated, where priority information is obtained from ...

To achieve a decision with which the group is satisfied, the group members must accept the judgments, and ultimately the priorities. This requires that (a) the judgments be homogeneous, and (b) the priorities of the individual group members be compatible with the group priorities. There are three levels in which the homogeneity of group preference needs to be considered: (1) for a single paired...

Congestion games are a well-studied model for resource sharing among uncoordinated selfish players. Usually, one assumes that the resources in a congestion game do not have any preferences regarding the players that can access them. In typical load-balancing applications, however, different jobs can have different priorities, and jobs with higher priorities get, for example, larger shares of pr...

OBJECTIVE A lack of agreement between clinician and patient priorities can impact the clinician-patient relationship, treatment concordance, and potential health outcomes. Studies have suggested that patients with osteoarthritis (OA) may prioritize comorbidities over their OA, but as yet no explicit systematic exploration of OA patients' priorities in relation to comorbidities exists. This stud...

Over the past three decades substantial research has been dedicated to the task of providing theoretical models for group decision processes. Unfortunately, many models remain grounded in single-period decision contexts. The current work investigates an extremely basic process approach to multi-criteria multi-period group decision-making. The time-series model considered incorporates factors re...

We study properties of priority synthesis [2], an automatic method to ensure desired safety properties in component-based systems using priorities. Priorities are a powerful concept to orchestrate components [3], e.g., the BIP framework [1] for designing and modeling embedded and autonomous systems is based on this concept. We formulate priority synthesis for BIP systems using the automatatheor...

Information-sharing is an integral part of cancer care. Several studies have examined the information needs of patients with various types of cancer. However, the priorities of information needs among patients with cancer have not been reported. A systematic review was performed to identify published studies that examined priorities of information needs in patients with cancer. PubMed (1966 to ...

BACKGROUND Quality end-of-life care depends on understanding patients' end-of-life choices. Individuals and cultures may hold end-of-life priorities at different hierarchy. Forced ranking rather than independent rating, and by-person factor analysis rather than averaging may reveal otherwise masked typologies. METHODS We explored Saudi males' forced-ranked, end-of-life priorities and dis-prio...

BACKGROUND Many stakeholders have little or no confidence in the ability of the public to express their opinions on health policy issues. The claim often arises that lay people prioritize according to their own personal experiences and may lack the broad perspective necessary to understand the needs of the population at large. In order to test this claim empirically, this study compares the pub...
