A quadratic model for production-inventory planning was made famous by Holt, Modigliani, Muth, and Simon in 1960 in [3], especially for its application to a paint factory. A discrete control version of a related quadratic production-inventory model was studied by Kleindorfer, Kriebel, Thompson,...

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...

Production scheduling problem of style good manufacturer involves seasonal stochastic demands for their goods and limited production capacities. As a result, some production must take place before the selling season starts. The problem can be cast as a stochastic optimal control problem over...

We consider a production-inventory planning problem with time-varying demands, convex production costs and a warehouse capacity constraint. It is solved by use of the Lagrangian form of the maximum principle. The possible existence of strong decision and forecast horizons is demonstrated. When...

This paper describes a maximum principle for distributed parameter systems, i.e. systems characterized by partial differential equations. The maximum principle is applied to solve the problem of a cattle rancher who must decide the number of cattle in different age groups to be bought and sold...
