This paper presents a simulation model to determine the impact of various container inspection protocols on the operation of a seaport container terminal. The inspection protocols are A) no inspection, B) container sampling with unloading and inspection coupled and C) inspection after unloading or decoupling inspection from unloading. Any sampling plan using Protocol B had  Read more »

This paper presents a modeling approach to determine the impact on throughput on air fleet resources on the operation of airports. The primary constraints for this analysis are i) adherence to schedules, ii) optimization of resource utilization and iii) reduction of operational costs. Any plan for an impact analysis on throughput on air fleet resources  Read more »

This paper presents the development of a conceptual framework for simulating interstate traffic. ProcessModel was selected as the simulation package. The framework has been successfully used to model interstate I-65 from Montgomery to Birmingham, AL. The study corridor begins near the Alabama River Bridge north of downtown Montgomery at mile marker 172 and extends north  Read more »

This paper presents a scenario analysis to determine the impact of a terrorist attack at Köhlbrand bridge across the river Elbe on the transportation chains on metropolitan Hamburg. It is of special interest to decide how to redirect trucks for the time of impossible traveling across the bridge as a consequence of the terrorist attack.  Read more »

This paper presents the development of a simulation model to evaluate the impact of increased 18-wheel truck traffic on the I-10 tunnel crossing the Mobile River in downtown Mobile, Alabama. The increased truck traffic is resulting from overall globalization of international trade and from truck traffic resulting from the expansion of the container terminal at  Read more »

This paper presents a scenario analysis to determine the impact of a ship disaster on river Elbe on the transportation chain of the port of Hamburg. It is of special interest to decide how to dodge ships for the time of the disaster, and to detour trains and trucks for loading and unloading. This paper  Read more »

This paper presents a simulation model to determine the impact of various container inspection sampling plans on the operation of a seaport container terminal. Of special interest is the turn around times for ships, trains and trucks. Included in this paper are the development of the simulation model, the experiment to evaluate the impact of  Read more »

This paper presents a conceptual framework for the development of seaport simulation models. The framework has been successfully used to model a bulk coal handling terminal, a seaport container terminal and an airport intermodal center. Included in this paper are a description of the modeling framework, descriptions of the application implementations and conclusions. Conceptual Framework  Read more »

This paper presents an analysis to determine the impact of bottlenecks on multimodal transportation chains. A bottleneck-analysis in general is a process related approach to identify shortages. In relation to transportation it is concerned with analysis of resource planes, depth of optimization of multimodal transportation, consideration of timeliness and concurrency while using resources, analysis of  Read more »

This research features the development of a transportation model that accurately shows the current state of Alabama’s infrastructure and allows for predictive analysis of the impact that relocating or developing industries would have on the local areas. A survey was conducted to determine freight volume and movement for a select group of industries. Data from  Read more »
