Base-Stock Policies For Lost-Sales Problems With Stochastic Lead Times (2007)
Robin O. Roundy, Ganesh Janakiraman
Subject Classification: Inventory/Production- base stock policies, stochastic lead times, lost sales. 0 We consider a system that faces stochastic demand, reviews the system periodically and places...
A Production-based Model for Predicting Heating Oil Prices (2007)
James R. Porter, Robin O. Roundy
We attempt to determine the impact of production decisions on the price of heating oil. A model for the production of distillate fuel oil is proposed. Its solution, obtained using stochastic dynamic...
Provably near-optimal sampling-based policies for stochastic inventory control models (2006)
Retsef Levi, Robin O. Roundy, David B. Shmoys
In this paper, we consider two fundamental inventory models, the single-period newsvendor problem and its multi-period extension, but under the assumption that the explicit demand distributions are...
Approximation algorithms for stochastic inventory control models (2005)
Retsef Levi, Martin Pál, Robin O. Roundy, David B. Shmoys
In this paper we address the long-standing problem of finding computationally efficient and provably good inventory control policies in supply chains with correlated and nonstationary...
Optimal capaciti, expansion and contraction under demand uncertain,” Working paper (2002)
Metin Çakanyıldırım, Robin O. Roundy
This paper presents a novel approach to compute optimal machine capacity expansion/contraction times under uncertain demand. A polynomial time Expansion/Contraction (EC) algorithm is developed to...

SeDFAM: Semiconductor demand forecast accuracy model (1999)
Metin C Akanyildirim, Robin O. Roundy
In the semiconductor industry, many critical decisions are based on demand forecasts. However, these forecasts are subject to random error. In this paper, we lay out a scheme estimating the variance...
Optimal capacity expansion strategies under demand uncertainty (1999)
Metin C Akanyildirim, Robin O. Roundy, Samuel C. Wood
This paper presents a novel approach to compute optimal machine, shop floor and shell space expansion times under uncertain customer demand. It considers multiple machine types and allows for...

Manufacturing logistic research: Taxonomy and directions (1999)
S. David Wu, Robin O. Roundy, Robert H. Storer
This paper examines research directions and opportunities in manufacturing logistics based on recommendations from an NSF sponsored workshop, and subsequent efforts by the authors to synthesize,...
Procurement of Common Components in a Stochastic Environment (1998)
Ramesh Srinivasan, Rangarajan Jayaraman, James A. Rappold, Robin O. Roundy, Sridhar Tayur
We consider a multi-period, two level product-component configuration where many of the components are common to several products. The demands for the products in any period are stochastic and...
