Exploring The Effects Of Cooperative Adaptive Cruise Control In Mitigating Traffic Congestion, Georges M. Arnaout

Engineering Management & Systems Engineering Theses & Dissertations

The aim of this research is to examine the impact of CACC (Cooperative Adaptive Cruise Control) equipped vehicles on traffic-flow characteristics of a multilane highway system. The research identifies how CACC vehicles affect the dynamics of traffic flow on a road network and demonstrates the potential benefits of reducing traffic congestion due to stop-and-go traffic conditions. An agent-based traffic simulation model is developed specifically to examine the effect of these intelligent vehicles on the traffic flow dynamics. Traffic performance metrics characterizing the evolution of traffic congestion throughout the road network, are analyzed. Different CACC penetration levels are studied.

Minimizing Post-Production Weight Growth In Tanks Using A Decision Analysis Model, Michael F. Cochrane

Engineering Management & Systems Engineering Theses & Dissertations

Post-production weight growth of tanks is an historic problem for the military. Tanks are difficult to transport because of their weight, and post-production modifications tend to cause this weight to increase over the lifecycle of the tank. In this thesis, a computer model is constructed which uses influence diagrams to model tank weight growth as a probabilistic process. Historical weight data for the MI Abrams tank program is used to derive probabilities for the model. The model is used to predict tank weight growth over both the short and long term with the goal of understanding more about how and …
