Strategic Sales Management Guided By Economic Regimes by Wolfgang Ketter, John Collins, Maria Gini, Alok Gupta and Paul Schrater We describe a method for automated characterization of market conditions, which we call economic regimes, and for prediction of future market conditions and of price trends. These predictions can then be used by the agent to make strategic and tactical sales decisions. The method is based on learning dominant market conditions, such as over-supply or scarcity, from historic data and using this knowledge, together with real-time observable information, to identify current market conditions, forecast market changes, and compute price trends over a planning horizon. The approach is presented in the context of the Trading Agent Competition for Supply Chain Management (TAC SCM), a market simulation in which six autonomous agents buy parts, assemble personal computers, and sell them in daily auctions to customers.
