Welfare Issues With Selective Breeding Of Egg-Laying Hens For Productivity

Agribusiness Reports

Today’s commercial laying hens have been selectively bred to produce more than 250 eggs per year. This unnaturally high level of productivity is metabolically taxing, often causing hens to suffer from “production diseases,” including osteoporosis and accompanying bone fractures, and can lead to reproductive disorders. Research suggests that the problem of osteoporosis may be worsening, possibly due to industry’s continuous push toward maximizing productivity. For decades, economic considerations have been valued and emphasized over the welfare of individual birds. An immediate change in priorities is needed to aggressively address welfare problems associated with selective breeding for egg production.

The Scale Of Operation, Profitability Based Productivity And Capacity Utilization In Seaports, The Case Study Based On The Colombo Seaport In Sri Lanka, 1980-2005, Sarath W.S.B Dasanayaka

Business Review

The Sri Lanka (formerly Ceylon), an island nation, is strategically located in the South Asian main sea routes as a gateway to the Far-East, the Middle-East, Europe, Africa and Australia. This supreme strategic hub location created commendable achievements in seaports in different magnitudes over time. More specifically, after 1977 economic policy reforms, the Colombo seaport has earned the reputation as the best managed and the most efficient hub port in the South Asia and the major transshipment center in the Indian Ocean. This success further strengthened by the liberalization of shipping in 1990 which was the land mark of changing …

E-Grocer Strategies: A Case Study, Anand Jeyaraj, Dubravka Cecez-Kecmanovic, Ville-Pekka Mäkeläine

Management Information Systems Faculty Publications

The recent bankruptcy of the eGrocer Webvan demonstrates that online retailers face enormous risks and hence need well thought out business strategies (Porter, 2001). This paper presents a longitudinal study of the business strategies of two eGrocers that use physical stores to house their Internet-based grocery operations (clicks-and-bricks) and two online only (pure-play) eGrocers. Our study results in a number of recommendations for successful eGrocer strategy configuration. Even though we focus on eGrocer’s strategies, we suggest that the lessons learned are of interest to other retailers planning to embark on eCommerce activities.

Real-Time Supply Chain Control Via Multi-Agent Adjustable Autonomy, Hoong Chuin Lau, Lucas Agussurja, Ramesh Thangarajoo

Research Collection School Of Computing and Information Systems

Real-time supply chain management in a rapidly changing environment requires reactive and dynamic collaboration among participating entities. In this work, we model supply chain as a multi-agent system where agents are subject to an adjustable autonomy. The autonomy of an agent refers to its capability to make and influence decisions within a multi-agent system. Adjustable autonomy means changing the autonomy of the agents during runtime as a response to changes in the environment. In the context of a supply chain, different entities will have different autonomy levels and objective functions as the environment changes, and the goal is to design …

The Sox-Rfid Connection, Porcher L. Taylor Iii, Nezih Altay

School of Professional and Continuing Studies Faculty Publications

Companies expect to gain many benefits from implementing Radio Frequency Identification (RFID) technology. Perhaps the one cited most often is lower supply chain costs, which result from the improved inventory visibility that the technology affords. But there's another often overlooked advantage that supply chain managers should know about: RFlD technology can help them fulfill the requirements of the Sarbanes-Oxley Act (SOX) if implemented and integrated properly. Conversely, RFID can complicate the already complex and costly internal mandates of SOX if the implementation is not approached the right way.

A Framework For Supplier Relationship Management (Srm), Sabine Moeller, Martin Fassnacht, Sonja Klose

Research Collection Lee Kong Chian School Of Business

We perceive growing expectations concerning the impact of the purchasing function and the suppliers on overall value creation of a firm. Purchasing is the gateway between the external suppliers and the internal functions creating and delivering value for customers. This shift has incredibly enhanced the importance of the supplier base. While the old arm length collaboration is perfectly suitable for some suppliers others should be treated as close partners. However, an overall framework of Supplier Relationship Management (SRM) integrating such different types of suppliers along the course of the relationship remains desirable. Our research aims to contribute by developing a …

Within this framework, research requirements can be analyzed via probability constraints on the output process, and the research effort that …

An Adaptive Tabu Search Heuristic For The Location Routing Pickup And Delivery Problem With Time Windows With A Theater Distribution Application, Robert E. Burks Jr.

Theses and Dissertations

The time constrained pickup and delivery problem (PDPTW) is a problem of finding a set of routes for a fleet of vehicles in order to satisfy a set of transportation requests. Each request represents a user-specified pickup and delivery location. The PDPTW may be used to model many problems in logistics and public transportation. The location routing problem (LRP) is an extension of the vehicle routing problem where the solution identifies the optimal location of the depots and provides the vehicle schedules and distribution routes. This dissertation seeks to blend the PDPTW and LRP areas of research and formulate a …

The railroad industry is experiencing a worldwide resurgence. International trade is booming as populations continue to grow and transportation infrastructures are nearing capacity. In the United States, the industry is being pressured to provide more services, while at the same time traffic levels are skyrocketing on a network that is much smaller than it was just fifty years ago. Additionally, security and safety issues are challenging the industry, as well as the regulatory agencies associated with railroading. To help with these problems, the industry is calling for more academic involvement through new degree programs and research initiatives. This paper reviews …

Optimal Order Quantities With Remanufacturing Across New Product Generations, Shantanu Bhattacharya, V Daniel R. Guide, Luk N. Van Wassenhove

Research Collection Lee Kong Chian School Of Business

We address the problem of determining the optimal retailer order quantities from a manufacturer who makes new products in conjunction with ordering remanufactured products from a remanufacturer using used and unsold products from the previous product generation. Specifically, we determine the optimal order quantity by the retailer for four systems of decision-making: (a) the three firms make their decisions in a coordinated fashion, (b) the retailer acts independently while the manufacturer and remanufacturer coordinate their decisions, (c) the remanufacturer acts independently while the retailer and manufacturer coordinate their decisions, and (d) all three firms act independently. We model the four …

First Annual Logistics Faculty Salary Survey, M Theodore Ferris, Terrance L. Pohlen, Jerry W. Wilson

Journal of Transportation Management

While the Association to Advance Collegiate Schools of Business International (AACSB) conducts an annual survey of business school faculty and administrative salaries, the data do not include salary figures for logistics (and related areas such as transportation and supply chain management) faculty. Since the growth in number of logistics faculty positions has continued to exceed the output of doctoral programs in the field for more than a decade, it is logical to assume that logistics faculty salaries, at all levels, are increasing. However, without factual data, what salary should a new logistics Ph.D. expect, and what should an administrator budget …

Using the examples of state highway finances for Kentucky …

Outsourcing To Non-Identical Suppliers Via Service Competition, Ehsan Elahi, Saif Benjaafar, Karen Donohue

Management Science and Information Systems Faculty Publication Series

In this paper, we consider a single buyer who wishes to outsource a fixed demand for a manufactured good or service at a fixed price to a set of N suppliers. We examine the value of competition as a mechanism for the buyer to elicit good service quality from her suppliers. In particular, we consider a scheme in which the buyer allocates a proportion of demand to each supplier, with the proportion a supplier receives increasing in the service level she offers. Suppliers compete for expected market share, which increases in the offered service level. The suppliers affect their service …

Modeling A Reparable Supply Chain And Applying Cpfr Concepts, Sandra A. Mayhall

Theses and Dissertations

The Air Force supply chain includes parts required to build, fix, or maintain aircraft delivered to the warfighter to carry out missions. Industry has shown that following Collaborative Planning, Forecasting, and Replenishment (CPFR) concepts, particularly reducing inventory through accurate demand forecasts, has increased profits in part by lowering the holding costs of inventory and increasing sales. This is analogous to the Air Force increasing aircraft availability. There is scant evidence that demand forecasts generated at any level in the Air Force are shared with the intent of coordinating replenishment. This thesis uses a simple discrete-event stochastic simulation model to show …

Plant Supply Logistics: Balancing Delivery And Stockout Costs, Jennifer A. Pope, James A. Pope

Journal of Transportation Management

A manufacturer leases rail cars to transport raw material from the supplier to the factory. The manufacturer must balance the costs of leasing rail cars versus stockouts (leading to plant closings) and inventory carrying costs. Using a model of circular queues and a simulation, the cost implications of leasing different numbers of rail cars are analyzed. It is concluded that stockout costs exceed the cost of excess inventory and capacity in the logistics system.

Pure Pallets: Effectiveness And Efficiency Impacts On The Defense Transportation System, Michael B. Mongold, Alan W. Johnson

Journal of Transportation Management

The military supply chain must explore initiatives to improve its ability to meet warfighter needs. One initiative, developed during operations in Afghanistan and Iraq is the pure pallet process—by consolidating material early in the supply chain into user-specific pallets, these pallets are able to transit the defense transportation system without being broken down en route, theoretically arriving to the warfighter in less time than prior break-bulk methods required. The pure pallet initiative’s effectiveness and efficiency was assessed by measuring customer requisition wait time, cargo throughput, and revenue performance. It was found that effectiveness increased, without corresponding losses in efficiency.

Working Toward A Seamless Supply Chain: An Exploratory Analysis Of The Impact Of Supply Chain On Company Performance, Carol J. Johnson, Lidiya Sokhnich, Charles Ng

Journal of Transportation Management

This paper explores the role that several supply chain dimensions play in achieving overall firm performance. Measures suggested in prior studies were factor analyzed for convergent and discriminant validity and then used in a regression model. This study uses data from the Council of Supply Chain Management Professionals (CSCMP) member firms, with top level supply chain managers as informants. The results suggest that of the three dimensions tested, two are significant contributors to firm profitability, including customer service and business process usage. Relationship confidence was not found to significantly impact overall firm performance.

Perceptions Of The Pure Pallet Program, Michael T. Dye

Theses and Dissertations

In coordination with USCENTCOM, USTRANSCOM, and the DLA, AMC implements the pure pallet program to improve warfighter support. The cornerstone of the pure pallet program rests upon the consolidation of materiel early in the supply-chain by constructing end-user specific pallets. This research utilized a web-based survey to measure the perceptions of the air transportation specialists and logistics readiness officers who are implementing the program on behalf of the Air Force. The results indicate that the pure pallet program is achieving its intended results; however, there is a perception problem. Recommendations center on educating personnel on the importance of suboptimization avoidance …

Hazardous Material Cargo Frustration At Military Aerial Ports Of Embarkation, Niel E. Christensen

Theses and Dissertations

Since military units often require critical hazardous materials in an expedited manner, identifying choke points within the supply chain is necessary to improve logistic support to front line forces. Hazardous materials are some of the most critical assets for the war fighter, as well as the most restrictive and often most time consuming for transportation. This research quantifies the extent that vendor and depot supplied cargo is being delayed at Aerial Ports of Embarkation. By looking at frustrated hazardous material at Charleston Air Force Base, South Carolina and Dover Air Force Base, Delaware, a case study methodology is used to …

Improving Maintenance Data Collection Via Point-Of-Maintenance (Pomx) Implementation, William D. Cone

Theses and Dissertations

Maintenance data collection is an integral part of flightline aircraft maintenance. Historically, this data was input via traditional keyboard data entry methods at a computer terminal. These terminals are typically located in the aircraft maintenance unit (AMU) facility, away from where the actual maintenance is being performed. In contrast to the traditional approach, the Point-of-Maintenance system (POMX) seeks to reduce the data entry burden while increasing data accuracy through the use of E-Tools such as ruggedized laptop computers and handheld portable maintenance aids (PMAs). POMX enables data entry at the aircraft or other maintenance location via wireless local area network …
