We show how an autonomous agent can useobservable market conditions to characterize the microeconomicsituation of the market and predict future market trends. Theagent can use this information to make both tactical decisions, suchas pricing, and strategic decisions, such as product mix andproduction planning. We develop methods to learn dominantmarket conditions, such as over-supply or scarcity, from historicaldata using Gaussian mixture models to construct price densityfunctions. We discuss how this model can be combined withreal-time observable information to identify the current dominantmarket condition and to forecast market changes over a planninghorizon. We forecast market changes via botha Markov correction-prediction process andan exponential smoother.Empirical analysis shows that the exponential smoother yields more accuratepredictions for the current and the next day(supporting tactical decisions),while the Markov correction-prediction process isbetter for longer term predictions (supporting strategic decisions).Our approach offers more flexibility thantraditional regression based approaches,since it does not assume a fixed functionalrelationship between dependent and independent variables. Wevalidate our methods by presenting experimental results in a casestudy, the Trading Agent Competition for Supply Chain Management.
