New solution concepts for n-decision maker conflicts based on generalized metarationalities for modelling possible human behaviour under conflict are proposed.A classification of these solution concepts,also called stability definitions,is presented both to simplify understanding and to illustrate important differences among different stability *** relationships among solution concepts are explored and new,more specific results are obtained in the comparison among existing stability concepts and the newly proposed *** informative example is used to demonstrate the applicability and insights of these solution concepts.

The strategic decisions and resulting consequences surrounding the conflict between the United States of America (US) and Iran regarding the Iranian nuclear program are formally investigated using a flexible decision methodology called the Graph Model for Conflict Resolution (GMCR). This highly controversial dispute caught the world's attention as concerns were growing that Iran would reach a position where it would be able to build nuclear weapons, thereby posing a risk to world security. While Iran insisted on its rights for the peaceful use of nuclear technology;the international community;led by the US, tried to discourage the nuclear activities of Iran to ensure its obligations to the non-proliferation of nuclear weapons. This led to an escalation of tension on both sides, with an extension of the nuclear program by Iran and an increase in sanctions by the US, before it was possible to arrive at a negotiated agreement. As demonstrated in this paper, a systematic GMCR investigation provides valuable strategic insights into this important conflict. Further, it illustrates ways in which the conflict could have evolved, as well as mechanisms for stopping an escalation like this in the future.

A formal methodology for analyzing the importance of weighing a decision maker＇s attitudes in a conflict is introduced and applied to the problem of negotiating a fair transfer of a brownfield property. A decision maker＇s attitudes are expressed in his consideration of his own preferences, as well as those of his opponents. Dominating attitudes are used to suggest that in a circumstance in which a decision maker takes into account multiple perspectives due to his attitudes, he may favor one perspective more heavily. The analysis of a brownfield acquisition conflict illustrates the types of insights that this methodology reveals.

Research discussing potential environmental toxins that may be related to the etiology of childhood leukemia has been growing. The suspected environmental contaminants include solvents, air pollutants, pesticides, and tobacco smoke. Exposure to various pesticides has come under particular scrutiny, with positive associations with childhood leukemia [1]. Poynter et al. [2] conducted a population-based study assessing the association between self-reported chemical exposures and odds of acute myeloid leukemia (AML) and myelodysplastic syndromes(MDS).

The key objective of this special issue of the Journal of Systems Science and Systems Engineering (JSSSE) is to assess papers con? taining leading-edge ideas on the theory and practice of conflict resolution and group decision making. Earlier versions of these fine papers were originally delivered by the authors at the 18th International Conference on Group Decision and Negotiation (GDN) which was held in Nanjing, China, from June 9 to 13,2018 (GDN 2018), and which appeared as extended abstracts in a conference proceedings ed让ed by Jiang et al.

The utilization of decision support systems which are flexible enough to handle information about cooperative behavior and stakeholder attitudes are useful for analyzing complex social conflicts. One such conflict which arose from the redevelopment of a private brownfield property in Kitchener, Ontario, Canada is examined using such a decision support tool. Specifically, a formal model referred to as COAT which allows for the examination of conflicts with both coalition and attitude properties is rigorously defined and then implemented within the framework of the Graph Model for Conflict Resolution in order that insights may be gained on how the decision makers can reach win-win resolutions.
