Benchmarking And Evaluating The Comparative Efficiency Of Urban Paratransit Systems In The United States: A Data Envelopment Analysis Approach, Hokey Min, Thomas E. Lambert
Benchmarking And Evaluating The Comparative Efficiency Of Urban Paratransit Systems In The United States: A Data Envelopment Analysis Approach, Hokey Min, Thomas E. Lambert
Journal of Transportation Management
Passenger rail service is perceived to provide important benefits to Michigan communities. However, the extent of these benefits has never been quantified in a systematic way. The study reported on here involved the performance of a broad based assessment of the community level benefits of passenger rail serv ice. The main objective of the research project was to estimate the full range of these benefits at the community level, as opposed to at the state level. Benefits were estimated for individual travelers, Amtrak expenditures, and local businesses. This research indicates local communities currently realize $62.0 million annually in benefits. Additional …
The Relationship Between Measures Of Operations Efficiency And Financial Success Of Truckload Motor Carriers: An Empirical Analysis, Ahren Johnston
The Relationship Between Measures Of Operations Efficiency And Financial Success Of Truckload Motor Carriers: An Empirical Analysis, Ahren Johnston
Journal of Transportation Management
This research paper examines the statistical relationship between clay to day performance and effi ciency measures and financial performance in the motor carrier industry. Key findings are that carriers with more miles per tractor per year, a larger average length of haul, more revenue per mile, and more revenue per tractor per week tend to perform better financially as measured in three separate models by operating ratio, return on assets, or return on equity. Unexpectedly, for the eight publicly traded carriers included in the analysis, there was a negative relationship between empty mile percentage and financial performance, indicating that carriers …

The accelerated globalization of logistics activities over the last several decades has spurred a rapid expansion of port facilities all cross the world. However, the recent slowdown of international trade, coupled with a global financial crisis, has created an on-going glut of international port facilities throughout the world. Although the abundance of port facilities provides more transshipment options for carriers and shippers, it makes the port selection decision more complex and difficult. To cope with this new set of challenges, this paper proposes a hybrid data envelopment analysis (DEA)/ analytic hierarchy process (AHP) model that is designed to identify factors …
Using Artificial Neural Networks For Transport Decisions: Managerial Guidelines, Robert L. Cook, Lawrence O. Jenicke, Brian Gibson
Using Artificial Neural Networks For Transport Decisions: Managerial Guidelines, Robert L. Cook, Lawrence O. Jenicke, Brian Gibson
Journal of Transportation Management
One information technology that may be considered by transportation managers, and which is included in the portfolio of technologies that encompass TMS. is artificial neural networks (ANNs). These artificially intelligent computer decision support software provide solutions by finding and recognizing complex patterns in data. ANNs have been used successfully by transportation managers to forecast transportation demand, estimate future transport costs, schedule vehicles and shipments, route vehicles and classify earners for selection. Artificial neural networks excel in transportation decision environments that are dynamic, complex and unstructured. This article introduces ANNs to transport managers by describing ANN technological capabilities, reporting the current …

Trip Patterns In Akure, Nigeria: A Land-Use Analytical Approach, A.O. Owolabi
Journal of Transportation Management
For transportation planners, the use of Origin-Destination (OD) matrix adjustment, is receiving considerable attention. However, there are concerns about the validity of results, primarily related to the number and location of traffic count posts. This leads to the question “What would be the best set of traffic count posts to use in OD matrix adjustment modules?” It has been proved that solving this problem is cumbersome. There have been several attempts (either exact or heuristic approaches) to address this problem. But due to the inherent complexities, there is no efficient and easy-to-use methodology able to address situations on the scale …
Developing Reverse Logistics Programs: A Resource Based View, Stephen E. Genchev, Timothy D. Landry, Patrica J. Daugherty, Anthony S. Roath
Developing Reverse Logistics Programs: A Resource Based View, Stephen E. Genchev, Timothy D. Landry, Patrica J. Daugherty, Anthony S. Roath
Journal of Transportation Management
Previous research proposes a six-process model for reverse logistics (RL) program design and execution. This manuscript advances RL related knowledge by incorporating the previous model into a broader theoretical framework, namely, the Resource Based View (RBV) of the firm. The current research employs exploratory techniques to investigate the applicability of RBV and its main tenants within the RL context. Based on in-depth interviews with 16 executives from seven different companies, the relationships among resources. RL capabilities, and RL competencies are explored.
Forward Positioning And Consolidation Of Strategic Inventories, Joseph B. Skipper, John E. Bell, William A. Cunningham Iii, Daniel D. Mattioda
Forward Positioning And Consolidation Of Strategic Inventories, Joseph B. Skipper, John E. Bell, William A. Cunningham Iii, Daniel D. Mattioda
Journal of Transportation Management
The forward positioning of strategic inventory in the supply chain has an impact on transportation times and is important for sensitive demand profiles. Consolidation of stocks creates pooling effects and minimizes costs. This study analyzes a current military case where forward consolidation of equipment is considered using optimization, and payback periods are calculated for the cost of consolidating inventory at one of six locations. Results indicate that forward positioning and consolidation reduces time and cost, and also creates savings in reverse logistics flows. The study has implications for geographically diverse supply chains such as humanitarian aid and emergency response operations.
A Study Of Logistics Strategies In Small Versus Large U.S. Manufacturing Firms, John E. Spillan, Jonathan W. Kohn, Michael A. Mcginnis
A Study Of Logistics Strategies In Small Versus Large U.S. Manufacturing Firms, John E. Spillan, Jonathan W. Kohn, Michael A. Mcginnis
Journal of Transportation Management
The research reported in this manuscript empirically compares the similarities and differences of logistics strategies for small and large manufacturing firms. The hypotheses focus on whether there are significant differences between logistics strategies of small and large manufacturing firms and whether logistics strategy outcomes differ. The findings indicate that there are many similarities but differences do exist. The results identify dimensions of logistics strategy and assess their impact on logistics coordination effectiveness, customer service commitment, and company/division competitive responsiveness.
Adapting Baumol’S Inventory Theoretic To Landed Cost Decisions, Stephan P. Brady, Peter F. Swan, Richard R. Young
Adapting Baumol’S Inventory Theoretic To Landed Cost Decisions, Stephan P. Brady, Peter F. Swan, Richard R. Young
Journal of Transportation Management
Major U.S. corporations have been importers for over 200 years. A significant impetus for “offshoring” has been reducing costs—usually labor costs. Often, other costs were overlooked. There has been a growing disenchantment with sourcing goods overseas, especially when there may be domestic alternatives as other costs begin to dominate. Baumol and Vinod’s Inventory Theoretic model was useful in adding transportation considerations. However, Baumol leaves out several important costs that unless considered in offshoring decisions can lead to suboptimal solutions. This paper extends that model, providing a prescriptive model that could be operationalized by firms to evaluate offshore sourcing decisions.
Fuel Costs And Supply Chain Decisions, Cliff Welborn
Fuel Costs And Supply Chain Decisions, Cliff Welborn
Journal of Transportation Management
The affect of rising fuel costs on the individual consumer is well documented in current media. Consumers are paying more for their basic necessities. Fuel surcharge, transportation cost, and logistics have become house hold words. The rising cost of crude oil creates an increase in fuel cost, and this creates an increase in the cost to transport products from one location to another. Managers, who are responsible for acquiring products and delivering them to customers, are also feeling the impact of higher fuel prices. This article will outline three significant areas where fuel prices are affecting U.S. supply chain decisions. …
