Preference Analysis and Decision Support in Negotiations and Group Decisions
Adiel Teixeira de Almeida, Tomasz Wachowicz · Group Decision and Negotiation · 2017
Making individual decisions is often challenging because the decision maker needs to take into consideration many different alternatives and conflicting issues (criteria) at the same time. The situation becomes even more challenging when decisions need to be made jointly or negotiated by many decision makers, each having their own viewpoints, preferences, aspirations or reservation levels. To find decision that would satisfy, at least partially, the needs of all parties involved, quantitative measurements may be introduced that allow the expression of the decision makers’ preferences in a more precise (numerical) way. Such measurements facilitate the analysis of how well the different alternatives meet the parties’ goals and find those that build an equilibrium from the viewpoint of mutual quality and effectiveness.
