Cng As A Feasible Replacement For The U.S. Transportation Sector, Veysel Uz
Theses and Dissertations
For many years there has been much attention on reducing U.S. fuel imports to improve the nation's energy independence. Much of the focus has been on the transportation sector, as it accounts for 28% of total U.S. energy consumption. This thesis examines compressed natural gas (CNG) as a possible alternative fuel for the U.S. transportation sector. To fully explore this possibility, it is essential to understand both the supply and demand sides of the problem. This research examines the availability and adequacy of CNG as a full or partial fuel replacement for U.S. transportation fuels, the factors that prevent CNG …

The Impact Of Supply Chain Business Processes On Competitive Advantage And Organizational Performance, John F. Perry Ii
Theses and Dissertations
Organizational performance has routinely been viewed through a limited scope primarily focused on functions, practices, and resources directly controlled by the focal organization, but supply chain management (SCM) has broadened this scope to incorporate all organizations along the supply chain. This shifted the notion of competition from that of between individual organizations to between supply chains. Supply chain management is an ever growing field; multiple SCM frameworks exist today and are being further developed and defined. Successful firms must reside on the leading edge of management techniques, theories, and practices in order to stay competitive in an ever growing, more …

The Relationship Between Key Supply Chain Process Implementation, Competitive Advantage, & Organizational Performance, Anthonelli White Jr.
Theses and Dissertations
In spite of an ever-accumulating body of research on the topic of supply chain management (SCM), an agreed upon definition or framework regarding its essential constructs or practices does not exist. There are, however, a few leading academic perspectives on SCM that have been bolstered by the acceptance of industry leaders. One such perspective is that presented by the Global Supply Chain Forum (GSCF). This study applies established survey methods to expand the body of knowledge pertaining to SCM by empirically validating the relationships conceptualized by the GSCF framework through an analysis of the perception of mid-level managers and senior-level …

The Welfare Of Animals In The Foie Gras Industry
Agribusiness Reports
The production of pâté de foie gras involves force-feeding ducks and geese by placing a long tube down the birds’ esophagi and pumping an unnatural quantity of food directly into their stomachs. Force-feeding induces hepatic lipidosis and causes the birds’ livers to become diseased and enlarged. Substantial scientific evidence suggests that force-feeding can cause pain and injury from feeding tube insertion, fear and stress during capture and handling, gait abnormality due to distended livers, pathologies in liver function, and increased mortality. Force-feeding birds to produce foie gras is detrimental to their welfare.

Lifecycle Pricing For Installed Base Management With Constrained Capacity And Remanufacturing, Andreas Robotis, Shantanu Bhattacharya, Luk N. Van Wassenhove
Research Collection Lee Kong Chian School Of Business
Installed base management is the policy in which the manufacturer leases the product to consumers, and bundles repair and maintenance services along with the product. In this article, we investigate for the optimal leasing price and leasing duration decisions by a monopolist when the production and servicing capacity are constrained. The effect of diffusion of consumers in the installed base is considered, with the ownership of the product resting with the monopolist during the product lifecycle. The monopolist operating the installed base jointly optimizes the profits from leasing the product/service bundle along with maintenance revenues and remanufacturing savings. We formulate …

Becoming Aware Of The Unknown: Decision Making During The Implementation Of A Strategic Initiative, Ronald Klingebiel, Arnoud De Meyer
Research Collection Lee Kong Chian School Of Business
This qualitative study analyzes the decision-making process involved in adapting preconceived courses of action during the implementation of a strategic initiative. We observe that the type of decision-making process hinges on the nature of managers’ emerging awareness of future events. When managers become aware of new uncertainty, the process involves selectiveness, deliberateness, and diligence. By contrast, when managers become aware of new certainty, the process conforms to the problem-solving adhocracy and decision-making messiness emphasized in prior literature. We summarize our findings in a framework, proposing that decision-level differences in awareness and uncertainty can explain the observed variation in strategic decision-making …

Agent Based Modeling And Simulation Framework For Supply Chain Risk Management, Tiffany J. Harper
Theses and Dissertations
This research develops a flexible agent-based modeling and simulation (ABMS) framework for supply chain risk management with significant enhancements to standard ABMS methods and supply chain risk modeling. Our framework starts with the use of software agents to gather and process input data for use in our simulation model. For our simulation model, we extend an existing mathematical framework for discrete event simulation (DES) to ABMS and then implement the concepts of variable resolution modeling from the DES domain to ABMS and provide further guidelines for aggregation and disaggregation of supply chain models. Existing supply chain risk management research focuses …

Research On Pre-Slaughter Stress And Meat Quality: A Review Of Challenges Faced Under Practical Conditions, A. Y. Chulayo, O. Tada, V. Muchenje
Slaughter and Slaughtering Practices Collection
Transportation and handling of animals are important components in meat production systems. Animals destined for slaughter are stressed by factors such as loading, transportation, restraint, handling, and novelty of the slaughter environment, adverse weather conditions, hunger, thirst and fatigue. When an animal is stressed in the pre-slaughter environment, there is a rapid release of enzymes, cortisols and catecholamines which may lead to depletion of glycogen, high meat ultimate pH (pHu) and dark cuts. Pre-slaughter stress also affects the physiology of the animal resulting in an increase in creatine kinase (CK) activity, glucose, lactate and other blood metabolites. Pre-slaughter stress and …

Extended Grazing: A Detailed Analysis Of Irish Dairy Farms, D. Läpple, T. Hennessy, M. O'Donovan
Farm Animal Husbandry Collection
Profitability and factors affecting grazing season length were econometrically analyzed using a representative sample of Irish dairy farms. The objective of this study was to explore what potential exists on Irish dairy farms to extend the grazing season and to quantify the possible economic benefits that result from lengthening the grazing season. Regression results indicate that location factors affect the length of the grazing season, but even when physical factors are controlled, farmer characteristics, such as education, also affect the grazing season length. The results of a panel data analysis show that significant cost reductions can be achieved by extending …

The Welfare Of Calves In The Beef Industry
Agribusiness Reports
Calves raised for beef often begin life unconfined, on rangeland where they are free to express their natural behavior. However, the welfare of calves can be compromised by certain specific management practices, typical on many ranching operations. These include castration of male calves, dehorning, and branding, all of which are usually performed without anesthesia or analgesia, pain relief of any kind. Welfare is also a concern during weaning, handling, auction, and transport, common stressful events that occur before calves are moved to feedlots. Techniques to minimize pain and distress should be used or further developed in order to address the …

The Benefit Of Information Sharing In A Logistics Outsourcing Context, Hossein Zolfagharinia, Michael Haughton
Business Faculty Publications
The goal of this article is to examine the value of information sharing in outsourcing of logistics activities. Our examination is in the context of a fairly complex network in which location and capacity of carriers are considered. The current research also examines the moderating effect of network settings on the benefit of information sharing. A core component of our methodology is use of computational experiments to provide a variety of logistics network conditions under which we investigate information sharing value. The investigation involves comparing two strategies, namely full and no information sharing. Underlying the experiments are procedures to optimise …

Impact Of Rotated Aisles On Travel Distance In Manufacturing Facilities, Dale Masel, Samantha Hedges
12th IMHRC Proceedings (Gardanne, France – 2012)
To design a facility, expected flows between the resources is one of the most important input. Flows are usually calculated given some statistics of previous periods or from the expected demand and the process required. However, in a refurbishing and recycling facility, flows are very fluctuating and not trivial to predict. The quantity produced by such facility not only depends on the demand but also on the supplies which are returned products under guaranty or discarded products after their end-of-use. The uncertainty and the variability on these supplies are often higher than the one on the demand which makes it …

Optimal Design Of Container Terminal Layout, Debjit Roy, Ren´E De Koster
12th IMHRC Proceedings (Gardanne, France – 2012)
Due to rapid growth in foreign trade using sea vessels, there is a growing focus in improving the infrastructure and operational efficiencies at the container terminals. Particularly, the operational responsiveness of loading and unloading of containers, affects the vessel idle times and profitability of the shipping liners. In this research, we deter- mine optimal stack layout design, which minimizes the container unload times using Automated Guided Vehicles (AGVs). To analyze alternate stack layout designs, we develop integrated queuing network models that capture the stochastic interactions among the container terminal processes (quayside, vehicle transport, and stack side), and provides realistic estimates …

Cycle Time Models For Aisle Changing As/Rs Considering Acceleration/Deceleration, Jörg Oser
12th IMHRC Proceedings (Gardanne, France – 2012)
In multi-aisle AS/RS systems one or more S/R machines serve several aisles with storage racks on both sides of the aisle. An important feature of multi-aisle configurations are aisle changing devices with transfer cars, curve guided aisle switching mechanisms or closed loop rail tracks with curved sections for a two-aisle layout. These systems offer an economic solution, when the number of storage and retrieval transactions is low and storage volume is high. One or several S/R machines each serving a specified number of aisles can be arranged in various layouts to meet the required storage capacity and throughput.

The Order Picking Problem In Fishbone Aisle Warehouses, Melih Celik, Haldun Sural
12th IMHRC Proceedings (Gardanne, France – 2012)
A recent trend in the layout design of unit load warehouses is the application of layouts without conventional parallel pick aisles and straight middle aisles. Two examples for such designs are flying- V and fish bone designs for single and dual command operations. In this study, we consider the same layout types under the case of multiple-item pick lists and show that, for both layout types, the routing problem can be solved in polynomial time. We also propose simple heuristics for this problem inspired by those put forward for parallel-aisle warehouses. Our computational results reveal that under certain cases, fish …
