Optimal Feedback Controls in Dynamic Stochastic Jobshops

Presman, Ernst; Sethi, Suresh; Suo, Wulin - 2009

We consider a production planning problem for a general jobshop subject to breakdown and repair of machines and subject to lower and upper bound constraints on work-in-process. The machine capacities and demand processes are assumed to be finite state Markov chains. The problem is to choose the...

Stochastic Multi-Product Inventory Models with Limited Storage

Beyer, Dirk - 2009

This paper studies multiproduct inventory models with stochastic demands and a warehousing constraint. Finite horizon as well as stationary and nonstationary discounted-cost infinite-horizon problems are addressed. Existence of optimal feedback policies is established under fairly general...

Optimal Feedback Production Planning in a Stochastic Two-Machine Flowshop

Lou, Sheldon - 2019

In this paper, we consider a production planning problem in a two-machine flowshop subject to breakdown and repair of machines and subject to non-negativity constraints on work-in-process. The machine capacities and demand processes are assumed to be finite state Markov chains. The problem is to...

Stochastic Production Planning with Production Constraints

Bensoussan, Alain - 2019

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...

An Optimal Stochastic Production Planning Problem with Randomly Fluctuating Demand

Fleming, Wendell H - 2017

This paper considers an infinite horizon stochastic production planning problem with demand assumed to be a continuous-time Markov chain. The problems with control (production) and state (inventory) constraints are treated. It is shown that a unique optimal feedback solution exists, after first...

Multilevel Hierarchical Decision Making in Stochastic Marketing-Production Systems

Sethi, Suresh - 2017

This paper presents an asymptotic analysis of hierarchical marketing-production systems with stochastic demand and stochastic production capacity modelled as finite state Markov processes. The decision variables used are advertising and production rates which influence capacity, demand, and...

Hierarchical Production Control in a Stochastic Manufacturing System with Long-Run Average Cost

Sethi, Suresh - 2009

This paper presents an asymptotic analysis of a stochastic manufacturing system consisting of parallel machines subject to breakdown and repair and facing a constant demand, as the rates of change of the machine states approach infinity. This situation gives rise to a limiting problem in which...
