Fuzzy preferences in bilateral negotiation support systems

The paper presents a bilateral negotiation support system (NSS) based on a multi-attribute utility model that adapts a fuzzy set methodology in determining user´s preference functions. The system can concurrently handle negotiations that span across multiple mediating issues in a manner that increases the joint utility of both parties. The NSS is expected to impart a more interactive and realistic approach to capturing uncertainties while developing the utility functions using the standard approach. The potentiality of the proposed NSS lies in its ability to allow negotiators to evaluate potential treaties quickly, explore alternate arrangements that reveal to be more advantageous to both parties than those which are arrived at intuitively
