Preference Analysis and Decision Support in Negotiations and Group Decisions
PADSING

Economics views the outcomes of group decision and negotiation processes in terms of efficiency. To measure outcome efficiency, the preferences of all participants must be obtained. Preference elicitation requires formalization of the decision problem and it relies on one of many elicitation methods. The result is a utility function or a simple scoring system which can be used to compare alternatives and concessions. They have been used to visualize the process and provide participants with graphical support tools. They also can be used for facilitation, arbitration and mediation as well as the specification of fair and equitable solutions.

Various formal methods, techniques and models may be used for supporting group decision-makers and negotiators in defining their goals, eliciting preferences and building the negotiation offers' scoring systems. Most of these methods are derived from the fields of decision analysis, multiple criteria decision-making and game theory. They need to be modified and adapted in order to fit the decision requirements of negotiations and group decisions. To this end, they need to allow for the consideration of time pressure, concession-making, imprecisely defined decision space, strategizing, as well as modification of preferences, and reservation and aspiration levels. These are some of the challenges faced by designers of models and algorithms and by developers of support tools and aids.

The main goal of the PADSING stream is to create a forum for the scientists, researchers and practitioners working in the field of group decision and negotiation analysis. The forum will allow the participants to exchange their experiences and discuss recent developments and results of their research. Thus we invite all the interested contributors to submit papers to the PADSING stream. The papers should focus on both the theoretical and empirical aspects of designing and using formal models and techniques for preference analysis and decision support in negotiation and group decision making.

Topics of interest include:

  • Formalizing group decision and negotiation problems
  • Designing and evaluating negotiation templates
  • Methodological issues of preference analysis
  • Handling the imprecise and vague preference information
  • Group decision support based on partial information
  • Application of MCDM methods for negotiation and group decision support
  • Game-theoretic symmetric and asymmetric analysis of the negotiation
  • Methods and models for mediation and arbitration
  • Experimental studies on use and usefulness of decision support in negotiation and group decision making
  • Experimental studies on decision makers' cognitive capabilities
  • Formal models of negotiation and group decision making support
  • Empirical applications of formal decision support tools in facilitating real-world negotiations and group decisions
  • Preference learning and modification
  • Preference aggregation of decision makers versus knowledge aggregation of experts
