The Long Haul: Risks Associated With Livestock Transport, Michael Greger

Agribusiness Collection

The Food and Agriculture Organization (FAO) of the United Nations describes live animal transport as “ideally suited for spreading disease,” given that animals may originate from different herds or flocks and are “confined together for long periods in a poorly ventilated stressful environment.” Given the associated “serious animal and public health problems,” the Federation of Veterinarians of Europe has called for the replacement of the long-distance transportation of live animals for slaughter as much as possible to a “carcass-only trade.”

In the United States, more than 50 million live cattle, sheep, and pigs and an unknown number of the more …

Management Information Systems Faculty Publications

Organizations make considerable investments in information technology to support their internal and external operations. For instance, a recent research report by Gartner Inc. indicates that worldwide spending on information technology will reach United States $3.3 trillion for the year 2008.

Innovation In Logistics Services, Carlos Mena, Martin Christopher, Mark Johnson, Fu Jia

Business Faculty Publications and Presentations

The logistics industry manages the flows of products, services and information across customers and suppliers, allowing the integration of supply chains. Innovations in logistics can therefore help improve efficiency and effectiveness across many sectors of the economy. Furthermore, innovation can also have a major impact in reducing the environmental burden of this industry, particularly in terms of pollution and greenhouse gas emissions.

This overall aim of this report is to understand how the government can encourage and facilitate innovation in the logistics industry. The study focuses mainly on the UK and on the role of third party logistics providers (3PLs). …

Antecedents Of Supply Chain Visibility In Retail Supply Chains: A Resource-Based Theory Perspective, Mark Barratt, Adegoke Oke

Management Faculty Research and Publications

Although visibility has become a popular buzzword in the supply chain literature it remains an ill-defined and poorly understood concept. It is assumed that if companies across supply chains have visibility of demand, inventory levels, processes, etc., that organizational performance improves. This research explores the antecedents of high levels of supply chain visibility from a resource-based theory perspective across five different external supply chain linkages. We find that the level of visibility across these linkages differs considerably based on various contributing factors which are both technology and non-technology based. Using resource-based theory, we identify those factors that can give a …

Product Complexity: A Definition And Impacts On Operations, Mark A. Jacobs

MIS/OM/DS Faculty Publications

The difficulty for organizations arises because neither complexity nor its impacts on performance are well understood (Fisher & Ittner, 1999b). The mechanisms through which it affects cost, quality, delivery, and flexibility need to be explained (Ramdas, 2003). However, this cannot happen until complexity can be explained theoretically. But, to build theory there must first be a common understanding about the construct of interest (Wacker, 2004). Only then can researchers operationalize it and search for meaningful relationships. In light of this, I develop a definition of complexity below. A sampling of the operations management literature is then presented within the context …

Research And Development Project Valuation And Licensing Negotiations At Phytopharm Plc, Pascale Crama, Bert De Reyck, Zeger Degraeve, Wang Chong

Research Collection Lee Kong Chian School Of Business

We describe a research and development project-valuation model developed for Phytopharm plc, a pharmaceutical development and functional food company based in Cambridgeshire, United Kingdom. Phytopharm uses the model to value the projects in its research and development portfolio, and in licensing negotiations with potential product development and marketing partners. We include different valuation methods, including net present value, decision analysis, and Monte Carlo simulation. We also consider the technological risks of product development, as well as the uncertainty of commercial success. In addition to determining a value for a product in development, the model proposes appropriate licensing contract structures. A …

A Field Study Of Rfid Deployment And Return Expectations, Jonathan W. Whitaker, Sunil Mithas, M. S. Krishnan

Management Faculty Publications

Radio Frequency Identification (RFID) technology promises to transform supply chain management. Building on previous research in information systems and supply chain management, this paper proposes a theoretical framework for RFID adoption and benefits, and tests the framework using data on U.S. firms. Our analysis suggests that there is a positive association between information technology (IT) application deployment and RFID adoption. We find that RFID implementation spending and partner mandate are associated with an expectation of early return on RFID investment, and a perceived lack of industry-wide standards is associated with an expectation of delayed return on RFID investment. These results …

Is The World Flat Or Spiky? Information Intensity, Skills, And Global Service Disaggregation, Sunil Mithas, Jonathan W. Whitaker

Management Faculty Publications

Which service occupations are the most susceptible to global disaggregation? What are the factors and mechanisms that make service occupations amenable to global disaggregation? This research addresses these questions by building on previous work by Apte and Mason (1995) and Rai, Patnayakuni, and Seth (2006) that focuses on the unbundling of information and physical flows. We propose a theory of service disaggregation and argue that high information intensity makes an occupation more amenable for disaggregation because the activities in such occupations can be codified, standardized, and modularized. We empirically validate our theoretical model using data on more than 300 service …

Customer Relationship Management: A Theoretical Overview And The High Cost Of Failure (A Case Study), Tamilla Curtis, Donald Barrere, Tom Griffin

Publications

Despite the significant benefits offered by the customer relationship management (CRM) strategy together with advanced technology, there is still a high rate of companies who fail to see results promised by CRM in order to achieve a competitive advantage. A review of the empirical literature together with the case study of the CRM implementation within a midsize financial firm will result in deeper understanding of current CRM practices that could contribute to better planning, selection, and implementation of customer relationship management programs.

Acute Stress Induced By The Preslaughter Use Of Electric Prodders Causes Tougher Beef Meat, R. D. Warner, D. M. Ferguson, J. J. Cottrell, B. W. Knee

Slaughter and Slaughtering Practices Collection

Adrenergic activation and hormone release preslaughter is an inevitable outcome of the systems used to move cattle to slaughter. The aim of this experiment was to investigate the effects of acute preslaughter stress in beef cattle on postmortem muscle metabolism and the meat quality, including consumer-assessed eating quality. Eighty-four cattle were used on three separate days, with ‘mobs’ of four cattle allocated to either a ‘control’ (no electric goads used preslaughter) or a ‘stress’ (six prods given with an electric goad over 5–10 min) treatment at 15 min preslaughter. Cattle undergoing the ‘stress’ treatment had higher plasma lactate at slaughter. …

Influence Of Free-Stall Base On Tarsal Joint Lesions And Hygiene In Dairy Cows, W. K. Fulwider, T. Grandin, D. J. Garrick, T. E. Engle, W. D. Lamm, N. L. Dalsted, B. E. Rollin

Housing and Confinement of Farm Animals Collection

The objective was to quantify the incidence of tarsal lesions and level of hygiene by stall bed type. Cows were scored on 100 dairies from Wisconsin, Minnesota, Indiana, Iowa, and New York in the fall and winter. Thirty-eight dairies used rubber-filled mattresses (RFM), 27 had sand beds, 29 had waterbeds, and 6 used compost packs (CPk). Stocking density, stall dimensions, bedding amount, bedding frequency, and type of bedding were recorded. One pen of early-lactation multiparous cows on each dairy was scored based on injury of the tarsal joints at the lateral and medial surfaces and tuber calcis at the dorsal, …

Chaos And Convergence On Bucket Brigade Assembly Lines, John J. Bartholdi, Iii, Donald D. Eisenstein, Yun Fong Lim

Research Collection Lee Kong Chian School Of Business

One way to coordinate the efforts of workers along an assembly line that has fewer workers than work stations is to form a bucket brigade. Each worker in a bucket brigade simultaneously assembles a single item (an instance of the product) along the line. The worker carries the item from work station to work station until either he hands of his item to a downstream co-worker or he completes the work for his item. The worker then walks back to get another item, either from his co-worker upstream or from a buffer at the beginning of the line. The most …

Global Sourcing And Logistics, Martin Christopher, Fu Jia, Omera Khan, Carlos Mena, Erik Sandberg

Business Faculty Publications and Presentations

The sourcing of products from across the global marketplace is an increasing trend associated with economic development. This trend is the result of many independent decisions taken by firms around the world looking for new sources of competitive advantage. However, these decisions can also have unintended consequences, exposing the firms to hidden costs and risks, creating congestion at different points in the global transport infrastructure and increasing emissions of pollutants and greenhouse gases.

This report presents the results of a project conducted in 2006-07, aimed at improving global sourcing practices, with a particular emphasis on the implications for the UK. …

Machine Scheduling Performance With Maintenance And Failure, Yunsong Guo, Andrew Lim, Brian Rodrigues, Shuang Yu

Research Collection Lee Kong Chian School Of Business

In manufacturing control, machine scheduling research has mostly dealt with problems either without maintenance or with deterministic maintenance when no failure can occur. This can be unrealistic in practical settings. In this work, an experimental model is developed to evaluate the effect of corrective and preventive maintenance schemes on scheduling performance in the presence of machine failure where the scheduling objective is to minimize schedule duration. We show that neither scheme is clearly superior, but that the applicability of each depends on several system parameters as well as the scheduling environment itself. Further, we show that parameter values can be …

Evaluation Of An Expanded Satellite Based Mobile Communications Tracking System, Maciek A. Novak, Alan L. Erera

Journal of Transportation Management

Since the terrorist events in the United States on September 11, 2001, the Federal Motor Carrier Safety Administration has been testing and evaluating cargo tracking technologies to improve the safety, security, and efficiency of commercial motor vehicle operations. While satellite-based systems used for tracking vehicles and cargo provide sufficient geographic coverage in the majority of the United States, there remain several vital regions that are uncovered and difficult to monitor. One such region is Alaska, where officials arc particularly concerned with the hazardous materials shipments that are transported parallel to the Trans-Alaska Pipeline. This article analyzes the risks and benefits …

Entry-Level Heavy Truck Drivers And Highway Safety: Is It Finally Time For Federally Mandated Training?, Harry L. Sink

Journal of Transportation Management

This article examines the need for mandated instruction and a uniform curriculum for entry-level commercial drivers. The study also addresses the discontinuity resulting from the establishment of a uniform licensing standard without requiring preparatory training. The research involves a review of Federal regulations pertaining to obligatory operator instruction in the air, water and rail mode. The investigation concludes that weak support and lobbying efforts by certain trucking interests have thwarted the adoption of mandatory instruction and/or a uniform curriculum. The study also highlights a pressing need for policy revision given the imminent retirement of many “baby boom” generation drivers.

A Decision Support Approach To Designing The Inland Logistics Network In China, Hokey Min, Hyun-Jeung Ko, Chin-Soo Lin

Journal of Transportation Management

With the unprecedented growth of international trade, a growing number of multinational firms have coped with logistical challenges of shipping products to and from unfamiliar territories in many countries. These logistical challenges include the cross-border transportation of products originated from inland port to another inland port isolated from major waterways. In particular, the lack of access to major waterways would not only constrain the intermodal transportation option, but also make door-to-door, containerized delivery services nearly impossible. Such a limited option would eventually lead to increased transportation costs and transit time, and thereby offset low-cost global sourcing advantages. To aid multinational …

U.S. Firm Outsourcing/Offshoring Practices And Plans: An Update, Robert L. Cook, Brian J. Gibson

A study of U.S. firm outsourcing and offshoring practices and future plans regarding supply chain activities provides an update for supply chain managers. Specifically, the reported information provides supply chain managers of manufacturing/ merchandising firms with a competitive benchmark; facilitates third party logistics manager strategic planning efforts and provides an input to U.S. transportation planners who determine future transport and infrastructure requirements. The study reports the responses of 151 Chief Purchasing Officers from U.S. firms. Firms are benefiting from outsourcing logistics and production activities and over one-third of the firms plan to increase outsourcing spend. In addition, 60 percent of …

Transportation Management Systems: An Exploration Of Progress And Future Prospects., Stanley E. Griffis, Thomas J. Goldsby

Journal of Transportation Management

This research reports the experiences of both adopters and non-adopters of transportation management system (TMS) technology. TMS adopters represent a diverse array of companies, with a surprisingly high percentage of adopters using outsourced services for decision support activities. Motives for adoption tend to align with the firm’s strategic needs though functionality focuses on the shipper’s day-to-day operational needs. While expectations of system performance and return on investment vary greatly, TMS users illustrate a generally high level of satisfaction. Non-adopters view decision support for transportation activities as a low priority. The article explores future prospects for TMS development and adoption.

Internal Versus External For Small Weapons Systems, Joseph S. Elkins

Theses and Dissertations

The acquisition method used to gain access to new technologies can heavily influence whether our war fighters have the required tools to fight increasing and constantly shifting global threats (Kessler and others, 2000). The purpose of this study was to investigate the process and results of internal laboratory development, testing and fielding of small weapons systems as compared to traditionally acquired systems which encourage customer pull and contractor development. This research provides insight into how Air Force Research Laboratory (AFRL) personnel choose an acquisition method, retain personnel capability, and maximize product capability. This study consolidates the opinions of subject matter …
