Equilibrium Analysis Based Pricing Mechanism in a MultiAgent Based Supply-Chain System

This paper describes the pricing mechanism adopted by UAM-TAC, a multi-agent based supply-chain system that will compete in TAC SCM (trading agent competition supply chain management) 2007. UAM-TAC consists of a procurement agent, an inventory agent, a production agent, a bidding agent and a delivery agent. The pricing mechanism is based on the equilibrium policy derived from the projected dynamic system, whose trajectory describes the dynamic evolution of product transactions, demand market prices, and shadow prices that the manufactures are willing to pay for the components. The game performance demonstrates that UAM-TAC is very responsive to the market price fluctuations and capacity variability.
