We describe UCFTAC, a trading agent based on control based principles, which has participated with success in 2006 Supply Chain Management Trading Agent Competition. The UCFTAC approach uses a sophisticated procurement strategy and an aggressive price control feature. It achieved competitive results in the TAC-SCM 2006 qualification round. Our design consists of a loosely coupled set of agent-managers, which exchange hints with each other and respond to direct commands from a central controller. We discuss the results obtained by the UCFTAC agent in the qualifying round of the trading agent competition.
