This note examines the stability of an optimal control problem based on a particular stochastic extension of the Nerlove-Arrow advertising model. It is shown that depending on the parameters of the problem and the initial conditions, the optimal solution may converge monotonically or...

This paper investigates the dynamic inventory model for the case when production in a period is restricted to a finite set of specified values. The model allows the production rate to be any value in the set {0, P, 2P, ..., mP}, where m is a nonnegative integer. It is assumed that the setup cost...
