The 5 Principles of Supply Chain Management - White Paper
Competitive advantage can be gained only if several key attributes exist in a supply chain. We identify the 5 Guiding Principles that must be followed in constructing and operating a world class, high velocity supply chain, illustrated with examples from a client’s experience. The Cliff’s Notes version of our academic paper “Collaborative Supply Chain System Design and Operation”.
Fulfilling Orders in a Large Scale On-line Retail System
We worked closely with one of the world’s leading on-line retailers to design an effective and efficient fulfillment system. This included establishing policies and procedures for the ordering, receiving, storing and shipping of goods. New approaches were established to position inventories in their multi-echelon system and using them to fulfill specific customer orders. We present a computationally tractable approach for a system that must fulfill many hundreds of thousands of orders daily.
Managing Inventories in a Large Scale On-line Retail Fulfillment System
In designing and operating a responsive, cloud-based order fulfillment system for a retailer with many millions of items, many factors must be taken into account. Determining stock levels quickly is a necessity. This paper describes a model for setting stock levels for each item, presents a computationally tractable method for determining their values, and provides numerical results that illustrate the applications of the model to the on-line retailer’s environment.
Maintenance Scheduling Models and Algorithms for Complex, Modular Systems
We explore new models of scheduled maintenance management for modular systems, consisting of multiple components with respective cycle limits. The cycle limit of each component specifies the time interval in which this component must be repaired or replaced. The goal is to compute a feasible maintenance schedule that minimizes cost. Applications of these models arise in Air Force aircraft maintenance other complex systems with required preventive maintenance. The models are computationally challenging. We develop two efficient and operationally tenable approximation algorithms. We prove constant factor worst-case guarantees for both algorithms, and present computational experiments showing that these algorithms perform within a few percent of optimality on operationally relevant instances.
Modeling Flows through Engine Repair Facilities
In this paper we present two types of models that can be employed to analyze the time dependent behavior of flows of engines through maintenance facilities. These models first focus on engine repair when the length of the planning horizon is assumed to be short, say a few weeks at most. Then we discuss how to extend one of our models to include both repairs of engines and components. We first consider depot-only models, and then two-echelon models.

An innovative inventory and production strategy to better manage items with unpredictable demands by increasing fill rates while reducing holding and backorder costs.
Concept of Operations for a Regional Telemedicine Hub to Improve Medical
Telemedicine (TM) is a tool that permits medical services to be provided remotely. Applications of telemedicine to disaster response began in the mid-1980s for natural disasters such as earthquakes, tsunamis, and hurricanes and for “staged” disasters in experiments and exercises. These activities led to the concept of a regional telemedicine hub (TMH) with an extended network of clinical providers, which potentially could alleviate problems associated with surge capacity during disaster response. However, health-related benefits associated with this organizational model for disaster-related telemedicine remain to be quantitatively tested.
In this paper, we describe a simulation study used to examine the operation of a regional telemedicine hub during the acute phases of hospital patient management in a hypothetical earthquake scenario. We explore the impact of using telemedicine to provide emergency specialty care to expand surge capacities at both local and regional levels.
Supply Chain Leadership Seminar: 3 Day Agenda
The seminar is based on a comprehensive case study of Nova, Inc., a fictional manufacturing company that has implemented a variety of new technologies, business processes and organizational changes to maintain competitiveness over the years, yet continues to lose market share. The case study uses actual operating data to illustrate business scenarios and the economic value of collaborative supply chain management techniques.

Aeroquip Group: A Troubled Ohio Plant Becomes An Exemplar
If there was ever a plant that pulled itself out of a morass of poor quality, declining sales, and low employee morale, it is Aeroquip Group’s 47-year-old factory in Van Wert, Ohio, near the Indiana border. Once a sad sack, it has become a superman of best practices that have been adopted by many of Aeroquip’s 35 other plants in the U.S. and abroad. By borrowing some of Van Wert’s ideas, in fact, some of those plants have won quality leadership awards in such states as Michigan and North Carolina, as well as many other honors.
