Optimale Sequenzen von Marktbeobachtungen und Lagerinventuren bei unsicherer Nachfrage

Summary

A profit-maximizing firm operating in a stochastic environment can supplement in any period its estimate of demand with a more or less intensive and a more or less costly market analysis. Similarly it has to decide upon physical stocktakings over time of its inventories. The balancing of information costs and losses caused by decisions based on inexactly known states of the market and the firm leads to optimal market and inventory monitoring policies for the planning period. The problem is solved with a discrete dynamic model of the firm by using the Kalman-filter.
