Using Active Learning To Enhance Supply Chain Knowledge, Joe B. Hanna, Brian J. Gibson, Randall Chapman Apr 2005

Using Active Learning To Enhance Supply Chain Knowledge, Joe B. Hanna, Brian J. Gibson, Randall Chapman

Journal of Transportation Management

The constantly evolving logistics discipline confronts practitioners with the challenge of keeping pace with the many advancements in the field. The authors examine ways in which logistics trainers may be able to improve their ability to effectively convey knowledge to logistics practitioners by supplementing the traditional lecture-based approaches with active learning exercises. The results of a recently conducted survey detailing current usage levels and approaches of active learning exercises, specifically simulations, by logistics educators is then presented. The paper also summarizes comments from individual simulation participants after they have completed a training experience designed to immerse them in a real …

Air Force Jp-8 Fuel Distribution System: A Statistical Analysis To Determine Where And When To Sample, Eric J. Heath Mar 2005

Air Force Jp-8 Fuel Distribution System: A Statistical Analysis To Determine Where And When To Sample, Eric J. Heath

Theses and Dissertations

The Air Force Petroleum Office at Wright-Patterson Air Force Base, Ohio collects JP-8 sampling data, but this data doesn't undergo analysis to determine the health of the base-level JP-8 fuel distribution system. Commanders possess no known confidence level when assessing base-level fuel health. Therefore, the objective of this research is to assess Air Force base-level fuel sampling data to determine the base-level sampling point that ensures a quality and healthy product at the aircraft. Also, this research seeks to identify how often correlation sampling should take place. Sample test pass rates are analyzed from three locations, receipt, storage, and vehicles/aircraft, …

Study On The Air Force's Ability To Field Senior Logistics Readiness Officers Experienced In Fuels Management, Keith A. Lewis Mar 2005

Study On The Air Force's Ability To Field Senior Logistics Readiness Officers Experienced In Fuels Management, Keith A. Lewis

Theses and Dissertations

A major initiative resulting from the 1999 Chief of Staff of the Air Force Logistics Review (CLR) was the development of the logistics readiness officer (LRO) career field, which combined three previous logistics fields; supply, transportation, and logistics plans. As a result, the training for a LRO promotes logistics function familiarity rather than expertise. This is of particular concern in the critical area of fuels management. Fuel is an absolute necessity in all military operations and its proper management is vital to mission success. The objective of this research is to determine the impact due to the LRO career field …

An Examination Of Reverse Logistics Factors Impacting The 463-L Pallet Program, Andrew J. Peterson Mar 2005

An Examination Of Reverse Logistics Factors Impacting The 463-L Pallet Program, Andrew J. Peterson

Theses and Dissertations

During peacetime operations, the process of tracking and managing 463-L assets within the Air Mobility Command airlift system results in infrequent imbalances or accountability issues. However, during contingency operations, AMC loses control of 463-L assets as they are turned over to the intra-theater distribution system. Since current contingency operations began in October of 2001, the Air Force has been unable to account for over 97,000 463-L pallets and 220,000 cargo nets. With a single pallet and net set costing over $1,300, the total value of the equipment unaccounted for exceeds $126 million. If not corrected, this failure to account for …

Pick-Up And Delivery: A Comparison Of Functional Alignments And The Impact On Customer Service And Vehicle Operator Utilization, Shawn K. Booher Mar 2005

Pick-Up And Delivery: A Comparison Of Functional Alignments And The Impact On Customer Service And Vehicle Operator Utilization, Shawn K. Booher

Theses and Dissertations

The Chief of Staff Logistics Review of 1999 examined a multitude of process issues and their resulting impact on organizational structure. A resulting initiative was to transition the pick-up and delivery function from the Material Management flight (LGRM) to the Vehicle Operations section (LGRVO). The motivation of this initiative, more specifically referred to as Supply/Transportation Reengineering, was to streamline similar processes, and to effectively and efficiently utilize resources. The goal of this transition was to use fewer people and resources to provide pick-up and delivery service to wing customers with minimal adverse impact to customer service and to improve overall …

A Case Study Of The Degree Of Collaboration Between Various Levels In The Reparable Chain In The United States Air Force, Robert A. Lee Mar 2005

A Case Study Of The Degree Of Collaboration Between Various Levels In The Reparable Chain In The United States Air Force, Robert A. Lee

Theses and Dissertations

Collaborative Planning, Forecasting, and Replenishment and other logistics processes were developed in the commercial sector to reduce total system costs of production while simultaneously providing reduction in inventory levels, improved customer service levels, greater flexibility in scheduling, greater velocity of inventory through the pipeline, and, as a result, greater profitability (Ploos van Amstel, 1990:1). Many companies including Wal-Mart, Motorola, Target, Johnson & Johnson, and Kellogg's, just to name a few, have seen great achievements since implementing CPFR processes. Can these processes be applied to the Air Force supply chain? This thesis intends to examine the flows and relationships to identify …

Using Depot Inventory Position To Determine Transportation Mode Of Retrograde Reparable Assets, Edward C. Snow Jr. Mar 2005

Using Depot Inventory Position To Determine Transportation Mode Of Retrograde Reparable Assets, Edward C. Snow Jr.

Theses and Dissertations

Air Force logistics policies direct the "expedited evacuation of repairables to the source of repair", in an effort to allow smaller inventories. Transportation Mode selection is based only on the asset itself. This focus works well when shipping assets out from the depot to a base. When a base ships an asset back to the depot however, the priority of the asset may not be the best way to select the transportation mode. The quantity of the assets at the depot may indicate that fast transportation is unnecessary. The depot may already have enough serviceable assets to meet demand or …

Optimization Model For Base-Level Delivery Routes And Crew Scheduling, Young-Ho Cha Mar 2005

Optimization Model For Base-Level Delivery Routes And Crew Scheduling, Young-Ho Cha

Theses and Dissertations

In the U.S. Air Force, a Logistic Readiness Squadron (LRS) provides material management, distribution, and oversight of contingency operations. Dispatchers in the LRS must quickly prepare schedules that meet the needs of their customers while dealing with real-world constraints, such as time windows, delivery priorities, and intermittent recurring missions. Currently, LRS vehicle operation elements are faced with a shortage of manpower and lack an efficient scheduling algorithm and tool. The purpose of this research is to enhance the dispatchers' capability to handle flexible situations and produce "good" schedules within current manpower restrictions. In this research, a new scheduling model and …

K-Center Problems With Minimum Coverage, Andrew Lim, Brian Rodrigues, Fan Wang, Zhou Xu Feb 2005

K-Center Problems With Minimum Coverage, Andrew Lim, Brian Rodrigues, Fan Wang, Zhou Xu

Research Collection Lee Kong Chian School Of Business

In this work, we study an extension of the k-center facility location problem, where centers are required to service a minimum of clients. This problem is motivated by requirements to balance the workload of centers while allowing each center to cater to a spread of clients. We study three variants of this problem, all of which are shown to be -hard. In-approximation hardness and approximation algorithms with factors equal or close to the best lower bounds are provided. Generalizations, including vertex costs and vertex weights, are also studied.

Managing Learning Resources For Consecutive Product Generations, Lieven Demeester, Mei Qi Feb 2005

Managing Learning Resources For Consecutive Product Generations, Lieven Demeester, Mei Qi

Research Collection Lee Kong Chian School Of Business

In this paper, we study how a firm should allocate its learning resources when it is concurrently producing two consecutive generations of one product. We define learning resources as scarce firm-specific resources that a firm allocates towards the improvement of the cost, quality or timeliness of its existing products and processes. We use empirically tested models for demand substitution and learning curves to formulate this problem, and we present our results as propositions with regard to the optimal time at which a firm should direct all its learning resources to the newer product generation, depending on the substitution rate of …

The Effects Of Land Transport On Animal Welfare, D. M. Broom Jan 2005

The Effects Of Land Transport On Animal Welfare, D. M. Broom

Transport of Farm Animals Collection

Animal welfare during and as a result of transport can be assessed by using a range of behavioural, physiological, pathological and carcass-quality indicators that are described in this paper. Measures of the extent of any disease, injury or mortality resulting from, or exacerbated by, transport are important because health is an important part of welfare. Many of the indicators are measures of stress as they involve long-term adverse effects on the individual. Factors affecting the welfare of animals before, during and after transport which are discussed are: definition of the responsibilities and competence, attitudes to animals and need for training …

The Effect Of Influence Tactics And Contingency Factors On The Adoption And Diffusion Of Is/It Innovations In Social Networks, Anand Jeyaraj Jan 2005

The Effect Of Influence Tactics And Contingency Factors On The Adoption And Diffusion Of Is/It Innovations In Social Networks, Anand Jeyaraj

Management Information Systems Faculty Publications

Despite considerable research on both adoption and diffusion of IS/IT innovations, there is a lack of coherent understanding of the processes by which innovations diffuse within social systems. This research proposes that the nature of the innovation diffusion process will depend on the characteristics of the innovation, the personal attributes of the individual, the interpersonal relationships, the composition of the social networks, and the specific influence tactics used by individuals. The empirical investigation involves a combination of three different research methods: meta-analysis, interpretive case studies, and simulation. The meta-analysis, at the organizational level, identifies the various factors (individual, dyad, social …

Information System Development Methodologies As Learning Systems, Anand Jeyaraj, Vicki L. Sauter Jan 2005

Information System Development Methodologies As Learning Systems, Anand Jeyaraj, Vicki L. Sauter

Management Information Systems Faculty Publications

Although information system development methodologies supposedly improve development processes and end-products, information systems have continued to fail. In practice, methodologies have not been universally accepted, and even when accepted, not consistently used. Often development teams adapt methodologies to respond to perceived problems in past applications and/or specifics of the project under consideration. While it is possible that a combination of these factors contributed to less-than-effective system development processes or final end-products, we believe that there may be a subtler explanation for such failures. Although methodologies recommend best practices for system development, they rarely prescribe mechanisms to capture or evaluate problems …
