The Eu Ban On Battery Cages: History And Prospects, Michael C. Appleby

State of the Animals 2003

On June 15, 1999, the European Union (EU) passed a directive on the welfare of laying hens, requiring that battery cages (so called because they are arranged in batteries of rows and tiers) be phased out by 2012. Enriched laying cages (which may also be arranged in batteries but which provide increased area and height, when compared with conventional cages, and a perch, nest box, and litter area) will still be allowed. This chapter outlines how this directive came about, and the social, economic, and political issues involved. It considers prospects for the future, both within and outside the EU, …

Inventory Competition In Make-To-Stock Systems, Ehsan Elahi, Saif Benjaafar, Karen Donohue

Management Science and Information Systems Faculty Publication Series

We present models for competition among multiple suppliers for demand from a single manufacturer. The suppliers produce to stock a single product and are allocated demand by the manufacturer based on the amount the amount of inventory they hold. We prove the existence of a Nash equilibrium for a broad class of market allocation schemes. For the special case of identical suppliers under either a stock-proportional or fill rate-proportional allocation, we show the uniqueness of the Nash equilibrium. Analysis of the Nash equilibrium for this case reveals that (a) the manufacturer benefits from competition (in the form of higher fill …

A New Node Centroid Algorithm For Bandwidth Minimization, Brian Rodrigues, F. Xiao, A. Lim

Research Collection Lee Kong Chian School Of Business

We propose a Node Centroid method with Hill-Climbing to solve the well-known matrix band-width minimization problem, which is to permute rows and columns of the matrix to minimize its bandwidth. Many heuristics have been developed for this NP-complete problem including the Cuthill-McKee (CM) and the Gibbs, Poole and Stockmeyer (GPS) algorithms. Recently, heuristics such as Simulated Annealing, Tabu Search and GRASP have been used, where Tabu Search and the GRASP with Path Relinking have achieved significantly better solution quality than the CM and GPS algorithms. Experimentation shows that the Node Centroid method achieves the best solution quality when compared with …

Managing Project Uncertainty: From Variation To Chaos, Arnoud De Meyer, Christoph H. Loch, Michael T. Pich

Research Collection Lee Kong Chian School Of Business

The article cites a study finding that accurately gauging the degree of uncertainty inherent in the projects can help project managers quickly adapt to it. Researchers studied 16 projects in areas including personal-computer development, telecommunications, Internet startups, pharmaceutical development, iron-ore processing, airship development, and building construction, to examine risk management and project outcomes. They found that most managers failed to recognize that there are different types of uncertainty, each requiring a different management approach. This paper explores uncertainty-based management, which derives planning, monitoring and management style from an uncertainty profile comprising four types of uncertainty: variation, foreseen uncertainty, unforeseen uncertainty, …

Short-Line Railroad Managers Discuss Class I Railroads, James C. Johnson, Diane J. Mcclure, Kenneth C. Schneider, Donald F. Wood

Journal of Transportation Management

Managers/owners of short-line railroads were queried about three issues: (1) How would you describe your company’s business relationship with the Class I railroad(s) with which you interchange traffic; (2) Do you believe that mergers between Class I railroads have been good or bad for short-line railroads; and (3) Besides merger activity, what do you believe will be the most important trend for Class I railroads in the next 10 years?

Liberalization Of International Air Transportation Markets: The Effect Of Terrorism On Market Trends, Dawna L. Rhoades

Journal of Transportation Management

Since the United States deregulated its airline industry with the Airline Deregulation Act of 1978, the international air transport industry has been on a path toward market liberalization. Market changes have included entry, capacity, and pricing freedom as well as increased levels of foreign ownership. The recent terrorist acts of September 11, 2001 have the potential to alter, if not reverse this course. This paper examines the forces fueling the trend toward liberalization and analyzes the impact of recent events on the future prospects of open aviation markets.

Journal of Transportation Management

The research reported in this manuscript provides several insights regarding the specific behaviors and traits of transportation salespersons as sought by a sample of shippers. Shippers in both manufacturing and non-manufacturing industries were asked to evaluate the importance of 30 potential salesperson characteristics. Overall, dependability, ethical conduct, honesty, provision of regular service, and solution selling were ranked as the most important (“must have”) characteristics. In addition to the overall rankings, t-tests were used to compare the manufacturing and non-manufacturing groups and ANOVA tests were used to compare the responses of shippers which were grouped by number of contacts from salespersons.

Solving The Pickup And Delivery Problem With Time Windows Using "Squeaky Wheel" Optimization With Local Search, Hongping Lim, Andrew Lim, Brian Rodrigues

Research Collection Lee Kong Chian School Of Business

The Pickup and Delivery Problem with Time Windows (PDPTW) is an important problem in fleet planning where decisions can involve not only dispatching company fleets but also the selection of carriers on certain routes. In this problem, vehicles travel to a variety of locations to deliver or pick up goods and to provide services. The increasing costs for additional vehicles motivate managers to optimize fleet usage. Managers also seek to achieve economical use of fuel, maintenance and overtime costs by minimizing travel distance and duration. As such, PDPTW impacts the interface of supplier-customer relationship management in the supply chain process …

On Uncertainty, Ambiguity, And Complexity In Project Management, Michael T. Pich, Christoph H. Loch, Arnoud De Meyer

Research Collection Lee Kong Chian School Of Business

This article develops a model of a project as a payoff function that depends on the state of the world and the choice of a sequence of actions. A causal mapping, which may be incompletely known by the project team, represents the impact of possible actions on the states of the world. An underlying probability space represents available information about the state of the world. Interactions among actions and states of the world determine the complexity of the payoff function. Activities are endogenous, in that they are the result of a policy that maximizes the expected project payoff.

Combining Two Heuristics To Solve A Supply Chain Optimization Problem, Hoong Chuin Lau, Yuyue Song

Research Collection School Of Computing and Information Systems

In this paper, we consider a real-life supply chain optimization problem concerned with supplying a product from multiple warehouses to multiple geographically dispersed retailers. Each retailer faces a deterministic and period-dependent demand over some finite planning horizon. The demand of each retailer is satisfied by the supply from some predetermined warehouse through a fleet of vehicles which are only available within certain time windows at each period. Our goal is to identify a combined inventory and routing schedule such that the system-wide total cost over the planning horizon is minimised. This problem in essence is an amalgamation of two classical …

Exchanging Preliminary Information In Concurrent Engineering: Alternative Coordination Strategies, Christian Terwiesch, Christoph H. Loch, Arnoud De Meyer

Research Collection Lee Kong Chian School Of Business

Successful application of concurrent development processes (concurrent engineering) requires tight coordination. To speed development, tasks often proceed in parallel by relying on preliminary information from other tasks, information that has not yet been finalized. This frequently causes substantial rework using as much as 50% of total engineering capacity. Previous studies have either described coordination as a complex social process, or have focused on the frequency, but not the content, of information exchanges. Through extensive fieldwork in a high-end German automotive manufacturer, we develop a framework of preliminary information that distinguishes information precision and information stability. Information precision refers to the …

Where Have All The On-Line Grocers Gone? Lessons Learned From The Demise Of On-Line Grocers, M Theodore Farris Ii, Phil Wilson

Journal of Transportation Management

The grocery concept has evolved over many years to drive cost out of the process. Grocery margins are very thin, typically ranging from 1% to 1 1/2 % such that the grocery business continues to look for innovative ways to take cost out of the process. Ordering groceries on the Internet was initially thought to be a very promising new opportunity. So what happened to on-line grocers? This paper considers what went right and what went wrong for the on-line grocers and uncovers a few logistics lessons along the way.

The Impact Of Lumper Costs, Empty Miles, And Shipment Size On The Profitability Of Motor Carriers: A Case Study, Hokey Min

Journal of Transportation Management

The passage of landmark deregulatory reforms in the Motor Carrier of Act of 1980 has constantly pressured the U.S. trucking industry to reduce transportation costs. Thanks to such pressure, total logistics costs have declined from 16.5% in 1980 to 10.1% of gross domestic product (GDP) in 2000. In particular, transportation costs have fallen from 7.6% to 5.9% of GDP in 2000. Transportation cost savings definitely benefit shippers, while jeopardizing the viability of carriers. To help transportation carriers cope with enormous cost pressure, this paper examines the impact that “lumper” costs, empty miles, and shipment size have on the very competitive …

An Analysis Of Intermodal Transport Carrier Selection Criteria For Pacific-Rim Imports To New England, Shashi N. Kumar, Vijay Rajan

Journal of Transportation Management

The introduction of double stack rail services opened up a variety of transportation options for shippers located in the North Eastern parts of the U.S. The availability of transcontinental double stack service from the Canadian West Coast has increased this option even further particularly because of a recent new service introduced by a small U.S. railroad company. The paper uses Analytical Hierarchy Process (AHP) methodology to provide a decision-making framework for the intermodal choices of shippers located in the region suitable for duplication elsewhere where similar options exist.

The Case For U.S. High Speed Rail, Drew Stapleton, Melissa Cooley, Darlene Goehner, Daoud Jandal

Journal of Transportation Management

High-speed rail is a form of self-guided ground transportation, which utilizes steel-wheels or magnetic levitation (i.e., Maglev) and can travel in excess of 200 miles per hour. High-speed ground transportation (i.e., HSGT) has been widely used in Europe and Asia, but the debate continues over the usefulness of high-speed rail in the United States. Several metropolitan areas in the United States have been identified as corridors that would benefit from HSGT. High speed rail can offer an alternative or a compliment to over-the-road and air transportation. Initial investment cost for this mode of transportation are high, but other factors such …

Interim Brigade Combat Team (Ibct) Munitions Distribution Study, Todd S. Bertulis

Theses and Dissertations

This research sought to describe an alternative way for calculating expected back order (EBO) for reparable inventory systems. The high costs associated with reparable items management, together with its importance for system's availability, make the assessment of back orders of great importance in supporting decisions of what-to-buy and where-to-locate those items. Starting at the point that existing models (METRIC, MOD-METRIC, and VARIMETRIC) rely on some assumptions that often cannot be met in real life, the proposed method (called P-METRIC), which is a mix of simulation and mathematical analytical model, relaxes assumptions about Demand, Time to Repair (TTR), and Ordering & …
