Ηλεκτρονικό σύστημα υποστήριξης διαπραγμάτευσης (Negotiation system)
Ρούσση, Κωνσταντίνα Ε.
In this thesis a negotiation support system was developed, which aims to facilitate two-party negotiation over two criteria. This system is called NJoint Gains and provides a structured process which helps the negotiating parties analyze their preferences and move gradually to a Pareto-optimal agreement. The NJoint Gains is an implementation of the jointly improving direction, developed by Ehtamo, Verkama and Hamalainen (1999) and Ehtamo, Kettunen and Hamalainen (2001), which is presented in detail in this thesis. Based on an initial tentative agreement the method evaluates the preferences of the two parties, calculates the improving direction and proposes a new mutually acceptable point along the compromise direction. Repeatedly moving along the jointly improving directions from the tentative agreements produced by the method, the negotiating parties can achieve a Pareto-optimal agreement.
