This book constitutes the refereed proceedings of the 19th International Conference on Group Decision and Negotiation, GDN 2019, held in Loughborough, UK, in June 2019. The field of Group Decision and Negotiation focuses on decision processes with at least two participants and a common goal but conflicting individual goals. Research areas of Group Decision and Negotiation include electronic negotiations, experiments, the role of emotions in group decision and negotiations, preference elicitation and decision support for group decisions and negotiations, and conflict resolution principles. The 17 full papers presented in this volume were carefully reviewed and selected from 98 submissions. They were organized in topical sections named: preference modeling for group decision and negotiations; collaborative decision making processes; conflict resolution; behavioral OR, and negotiation support systems and studies.

This book constitutes revised selected papers from the 16th International Conference on Group Decision and Negotiation, GDN 2016, held in Bellingham, WA, USA, in June 2016. The GDN meetings aim to bring together researchers and practitioners from a wide spectrum of fields, including economics, management, computer science, engineering, and decision science. The 12 papers presented in this volume were carefully reviewed and selected from 70 submissions. They deal with the fundamental part of all decision processes and individual preferences; the situations of group decision making; the collective decision making in situations characterized by a higher level of conflict; and the group processes and negotiations in different subject areas.

This book constitutes the refereed proceedings of the 18th International Conference on Group Decision and Negotiation, GDN 2018, held in Nanjing, China, in June 2018. The field of Group Decision and Negotiation focuses on decision processes with at least two participants and a common goal but conflicting individual goals. Research areas of Group Decision and Negotiation include electronic negotiations, experiments, the role of emotions in group decision and negotiations, preference elicitation and decision support for group decisions and negotiations, and conflict resolution principles. The 15 full papers presented in this volume were carefully reviewed and selected from 143 submissions. They were organized in topical sections named: theoretical concepts of group decision and negotiation; decision support and behavior in group decision and negotiation; and applications of group decision and negotiations.

Marita Haas claims that social processes are decisive for the success of SME networks and creates a phase concept based on group theory that describes how owners of small enterprises enter into a cooperation. The framework is applied to three network formation cases in Austria, Belgium and Turkey. The author shows that group theory is a useful tool to understand and anticipate processes in networked organizations and indicates that the group formation process must be accomplished before a network will be able to create benefits.

Dieses Buch gibt eine fundierte Einfuhrung in Informationssysteme zur Unterstutzung der Unternehmensfuhrung. Es verbindet informationstechnische und betriebswirtschaftliche Aspekte, die zum Verstandnis dieser komplexen Systeme erforderlich sind. Durch Einbeziehung aktueller Ergebnisse sowohl aus der theoretischen, als auch der empirischen Forschung wird ein aktuelles Bild des Gebietes in Theorie und Praxis vermittelt. Erstmals steht damit eine kompakte und zugleich umfassende deutschsprachige Gesamtdarstellung dieses Gebietes zur Verfugung.

Die Arbeit stellt einen Beitrag zur Theorie entscheidungsunterstutzender Systeme fur Gruppen (Group Decision Support Systems - GDSS) dar. Sie erweitert das in der Literatur bisher benutzte hierarchische Konzept der Trennung zwischen Individual- und Gruppenebene um die explizite Modellierung von Ruckwirkungen von (vorlaufigen) Ergebnissen der Gruppenebene auf individuellen Bewertungen. Ausgangspunkt ist ein umfassender Literaturuberblick, der ein breites Spektrum an Ansatzen zur Unterstutzung von Gruppenentscheidungen vorstellt und klassifiziert. Darauf aufbauend wird das eigene Konzept ruckkopplungsorientierter GDSS zunachst in allgemeiner Form entwickelt und anschliessend fur unterschiedliche Entscheidungsverfahren ausformuliert. Abschliessend wird ein konkret implementiertes experimentelles GDSS vorgestellt. Die Arbeit deckt somit das gesamte Spektrum von der Entwicklung allgemeiner theoretischer Grundlagen der Unterstutzung von Gruppenentscheidungen bis zur konkreten Systementwicklung ab. Das Buch wurde in Osterreich vom Kardinal-Innitzer-Studienfonds mit einem Forderungspreis ausgezeichnet.
