Sizing Mobility Readiness Spares Packages For Today's Warfighting Units, Christopher M. Beckley

Theses and Dissertations

As the Air Force transforms from a garrisoned force into a light expeditionary force, one area for restructuring is the manner in which mobility readiness spares packages (MRSPs) are managed and stocked. For a war tasking, thirty days supply is typically deployed in a MRSP as it is assumed that there will be no re-supply for thirty days. Studies of combat operations from the past decade suggest that thirty days without re-supply is an outdated assumption. The objective of this thesis is to economically build a robust MRSP that is flexible enough to provide adequate support for a variety of …

Carcass Composition And Meat Quality Of Three Different Iberian × Duroc Genotype Pigs, Rosario Ramírez, Ramon Cava

Slaughter and Slaughtering Practices Collection

Carcass composition and meat quality of Longissimus dorsi (LD) and Biceps femoris (BF) muscles from three different Iberian × Duroc genotype pigs were studied: GEN1: ♂ Iberian × ♀ Duroc1; GEN2: ♂ Duroc1 × ♀ Iberian; GEN3: ♂ Duroc2 × ♀ Iberian. Duroc1 (DU1) were selected for the manufacture of dry-cured meat products while Duroc2 (DU2) were pigs selected for meat production, with high percentages of meat cuts and low carcass fat. Genotype had a significant effect on the differences found while sex had not. GEN2 showed the highest weights at days 180 and 238 of weaning and the highest …

Class Viiia Materiel: What Problems Were Encountered Transiting Oif Air Transshipment Nodes?, Jessica L. Buck

Theses and Dissertations

Medical cargo (Class VIIIA) is critical to the success of the United States military stationed across the globe; therefore, the military must successfully ship its Class VIIIA materiel to the Warfighter. The shipping and handling of the time and temperature sensitive Class VIIIA materiel is a complex process. Since the initial stages of Operation IRAQI FREEDOM (OIF) the medical field has complained about Class VIIIA materiel arriving unserviceable to the final destination. Unserviceable materiel includes items that expired over time and items that expired from exposure to temperatures outside of their allowable range. This thesis focused on one possible area …

The Viability Of The Air Mobility Command Pure Pallet Program For Us Army Reparable Retrograde Shipments, William L. Jackson Jr.

Theses and Dissertations

Last year, Congress approved $17.1 billion dollars, an increase of $4 billion dollars more than originally was requested by the Bush Administration, for US Army vehicles to be repaired or replaced (commonly referred to as reset) as a result of military operations in Iraq and Afghanistan. A large portion of the repair workload falls upon the Army depots in Anniston and Red River in Texarkana, Texas and must rely on the DOD transportation system for air and surface movement of retrograde cargo deemed serviceable and unserviceable to fill requisitions and backorders for entry into the national supply inventory. Headquarters Air …

Commercial Firm Training Practices Versus Aerial Port Hazardous Cargo Frustration, Jill L. Maynard

Theses and Dissertations

The military is dependent on commercial vendors to augment their supply system, to include hazardous materials. Hazardous materials must be packaged and labeled differently than general cargo for shipment in the defense transportation system. Previous research has shown there is an increase in frustration levels at Aerial Ports of Embarkation. The reasons for frustration range from minor discrepancies to improperly completed shipping documents. This research investigates if commercial companies are a cause of the frustration problems. A case study methodology was used to investigate training practices of companies that had frustrated hazardous cargo at either Charleston or Dover Aerial Ports. …

A Multi-Objective Decision-Making Model For Resources Allocation In Humanitarian Relief, Seungbae Park

Theses and Dissertations

This thesis addresses the critical resource allocation in the initial days of a disaster relief operation. One of the most important and essential components of relief operations is the allocation of scarce resources to accomplish the relief efforts. Every operation for disaster relief needs various critical resources whether they are personnel, equipment, supplies, or simply finances. Several research efforts for disaster relief have suggested methods to allocate scarce resources across a variety of competing objectives and programs in a disaster relief operation. Many of those efforts focused on optimizing a mathematical programming model subject to budget constraints. However, capturing the …

A Comparison Of Cross Training Policies In Different Job Shops, Kum Khiong Yang

Research Collection Lee Kong Chian School Of Business

This research compares a set of cross-training policies represented by different numbers of cross-trained workers, additional skills per cross-trained worker, and additional machines. The policies are evaluated in job shops, represented by different efficiency losses, labour utilization, variability in processing times, and worker absenteeism. Our results show that adding one machine in each department and cross-training one or two workers from each department with one additional skill is generally sufficient to realize most of the benefits of cross-training. Cross-training is thus beneficial in most job shops, unless the cost of the minimal training and spare machines is high. Our results …

Outsourcing Via Service Competition, Ehsan Elahi, Saif Benjaafar, Karen Donohue

Management Science and Information Systems Faculty Publication Series

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 potential suppliers. We examine the value of competition as a mechanism for the buyer to elicit service quality from the suppliers. We compare two approaches the buyer could use to orchestrate this competition: (1) a Supplier-Allocation (SA) approach, which allocates a proportion of demand to each supplier with the proportion allocated to a supplier increasing in the quality of service the supplier promises to offer, and (2) a Supplier-Selection (SS) approach, which allocates all …

Logistics Network Design With Supplier Consolidation Hubs And Multiple Shipment Options, Michelle L. F. Cheong, Rohit Bhatnagar, Stephen C. Graves

Research Collection School Of Computing and Information Systems

An important service provided by third-party logistics (3PL) firms is to manage the inbound logistics of raw materials and components from multiple suppliers to several manufacturing plants. A key challenge for these 3PL firms is to determine how to coordinate and consolidate the transportation flow, so as to get the best overall logistics performance. One tactic is to establish consolidation hubs that collect shipments from several suppliers, consolidate these shipments, and direct the consolidated shipments to the appropriate manufacturing plant. We consider the network design problem to implement this tactic, namely deciding the number, location and operation of consolidation hubs …

Virtual Transfer Pricing Mechanisms In Global Supply Chain, Kun Liao, Jie Jennifer Zhong

All Faculty Scholarship for the College of Business

Increasingly global firms establish plants across their national borders while utilizing their home country suppliers in diverse locations. In view of complex risk factors including political uncertainty, tax rate differences, exchange risks and labor condition changes, the issues of optimizing profits through their global operations have received much attention from both academic researchers and executives. Yet, little attention has been paid in regard to virtual transfer pricing in the global supply chain. In this paper, a virtual transfer pricing model is proposed by using contract bundle within a global supply chain to lower the risks and maximize the profit potentials.

Effect Of Stall Base Type On Herd Health, Costs, And Producer Satisfaction, 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 of this field study was to compare effect of stall base on herd health, stall maintenance, bedding cost, and producer satisfaction. Ninety-one dairies visited during a 4-mo period starting October 14, 2005 included 33 rubber-filled mattress (RFM), 27 sand, and 31 waterbed (WB) dairies. In this study, percent culled was higher for RFM (P = 0.001) and sand (P = 0.06) than WB stall base dairies. Percent of cows in fourth lactation or greater was higher on WB than either RFM (P = 0.01) or sand (P = 0.02) dairies. There was no difference between base types for …

The Welfare Of Animals In The Meat, Egg, And Dairy Industries

Agribusiness Reports

Each year in the United States, approximately 11 billion animals are raised and killed for meat, eggs, and milk. These farm animals—sentient, complex, and capable of feeling pain and frustration, joy and excitement—are viewed by industrialized agriculture as commodities and suffer myriad assaults to their physical, mental, and emotional well-being, typically denied the ability to engage in their species-specific behavioral needs. Despite the routine abuses they endure, no federal law protects animals from cruelty on the farm, and the majority of states exempt customary agricultural practices—no matter how abusive—from the scope of their animal cruelty statutes. The treatment of farm …

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.

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.

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 …
