A Cooperative Trading System Model Aiming at Efficient Supply-and-Demand Balance

Abstract

This paper proposes a new cooperative trading system model using marketers’ evaluation functions of their preferences to goods. We introduce a computational market mechanism as a solution to the distribution of goods according to the market model. Every customer would not accept any reduction of evaluation without any merit like price cuts. As a result, suppliers must pay rewards to customers to cooperate with each other. This approach provides us with an on-line estimation of the evaluation functions and rewards. In addition to them, it can deal with time-variable tendency of customers.
