Although a broker plays an important role in e-marketplaces, theory and guidelines for matching between buyers and sellers in multi-attribute exchanges are limited. Therefore, a challenge for a broker＇s responsibility is how to maximize a buyer＇s total satisfaction degree as its goals under the consideration of trade-off between a buyer＇s buying quantity and price paid to a seller, and other attributes. To solve this challenge, this paper proposes an economic model-based matching approach between a buyer＇s requirements and a seller＇s offers. The major contributions of this paper are that （i） a broker can model a seller＇s price policy as per a buyer＇s buying quantity through communication between a broker and a seller; （ii） due to each buyer＇s different quantity demand, a broker models a buyer＇s satisfaction degree as per a buyer＇s buying quantity based on communication between a broker and a buyer; and （iii） to carry out a broker＇s matching processes, an objective function and a set of constraints are generated to help a broker to maximize a buyer＇s total satisfaction degree. Experimental results demonstrate the good performance of the proposed approach.展开更多
