On the Real-Time Coalition Formation Support Algorithm for the Electronic Group Buying

摘要

Group buying is one form of electronic commerce that is growing quickly. In group buying, the unit price of goods changes with the number of buyers, and a buyer can purchase goods at a lower price if many buyers participate in group buying. Thus, in the group buying on the Internet, we can purchase a good at a lower price. In commercial transactions on the Internet, the number of buyers and sellers changes dynamically change because anybody can participate wherever they want. Therefore, it is difficult for buyers to form a large group, and the advantage of group buying is lost. In this paper, we propose a real-time coalition formation method based on Genetic Algorithms.
