This paper considers an infinite horizon stochastic production planning problem with the constraint that production rate must be nonnegative. It is shown that an optimal feedback solution exists for the problem. Moreover, this solution is characterized and is then compared with the solution of...

First-order necessary and sufficient conditions are obtained for the following quasilinear distributed-parameter optimal control problem:max{J(u)=IntF(x,u,t)dw IntG(x,t)dsigma},subject to the partial differential equationA(t)x =f(x, u, t),where t, u, G are vectors and x, F are scalars. Use is...

An exploration and consumption model for exhaustible natural resources is used to formulate a deterministic optimal control problem over an infinite time horizon. A dynamic programming approach is employed throughout. The non-linear partial differential equation which results from an application...

A general sates-advertising model is developed in which the state of the system represents a population distribution over a parameter space. With appropriate interpretations, this can include income, family size, geographic distributions, etc. Effects of information diffusion, interaction, and...

The method of variational inequalities is a useful theoretical tool in stochastic control, but there are few problems in which this method leads to an explicit solution. We present such a problem drawn from portfolio management. An agent can distribute his wealth between two investments, one...

An asymptotic analysis of a hierarchical manufacturing system with machines subject to breakdown and repair is presented. The machine fluctuations are much faster than the accumulation and discounting of costs, and this gives rise to a limiting problem in which the stochastic machine...
