We present and analyze results from the 2004 Trading Agent Competition supply chain management scenario. We identify behavioral differences between the agents that contributed to their succcess in the competition. In market for components, early procurement remained an important factor despite rule changes from the previous year. We provide additional experimental evidence to confirm that this phenomenon is still rational. Strategic interations also played an important role in procurement; one agent, FreeAgent, employed a strategy designed to block other agents ’ access to suppliers at the start of the game. The different ways agents responded to this challenge were an important factor in the outcome of the tournament. In the customer sales market, average selling prices were a decisive difference between the top agents. Our analysis shows that the economic forces of supply and demand were key factors in determining overall market prices, and that some agents were more adept at finding and exploiting advantageous market conditions. 1
