Computation of Approximate Optimal Policies in a Partially Observed Inventory Model With Rain Checks

Bensoussan, Alain - 2020

This paper proposes a new methodology to solve partially observed inventory problems. Generally, these problems have infinite dimensional states that are conditional distribution of the inventory level. Our methodology involves linearizing the state transitions via unnormalized probabilities. It...

Solution to a Class of Two-stage Stochastic Programs with Multivariate Normal Uncertainty

Bansal, Saurabh; Dyer, James - 2013

We provide results for an efficient analytical valuation of partial moments of the multivariate Gaussian distribution over convex polyhedrons to aid the solution, sensitivity analysis and structural analysis of a large number of two-stage resource acquisition and allocation problems. These...

A Dynamic Lot Sizing Model with Learning in Setups

Chand, Suresh; Sethi, Suresh - 2017

This paper considers the dynamic lot sizing problem of H. M. Wagner and T. M. Whitin with the assumption that the total cost of n setups is a concave nondecreasing function of n. Such setup costs could arise from the worker learning in setups and/or technological improvements in setup methods....

Asymptotic Optimal Feedback Controls in Stochastic Dynamic Two-Machine Flowshops

Sethi, Suresh; Yu Zhou, Xun - 2014

In this paper, we treat an optimal control problem of a stochastic two-machine flowshop with machines subject to random breakdown and repair. While the problem is difficult to solve, it can be approximated by a deterministic problem when the rates of machine failure and repair become large....

Modeling Supply Chain Planning Under Demand Uncertainty Using Stochastic Programming : A Survey Motivated by Asset-Liability Management

Sodhi, ManMohan S.; Tang, Christopher S. - 2009

We extend the linear programming (LP) model of deterministic supply-chain planning to take demand uncertainty and cash … for making modeling/solution choices in research and in practice to manage the risks pertaining to unmet demand, excess … inventory and cash liquidity when demand is uncertain …

The Impact of Innovation and Organizational Factors on Aps Adoption : Evidence from the Dutch Discrete Parts Industry

van Hezewijk, A.P; van Assen, Marcel; van de Velde, S. L. - 2014

Advanced Planning and Scheduling (APS) systems have gained renewed interest from academics and practitioners. However, literature on APS adoption is scant. This study explores the impact of organizational and innovation related factors on the adoption of APS systems from a factors approach. The...
