An Optimization Framework For Integrating Variable Capacity And Pavement Thickness Requirements In Highway Cost Allocation, Saurav Kumar Dubey Aug 2017

An Optimization Framework For Integrating Variable Capacity And Pavement Thickness Requirements In Highway Cost Allocation, Saurav Kumar Dubey

Doctoral Dissertations

The objective of Highway Cost Allocation (HCA) is to distribute or allocate in a fair and rational manner the cost of a transportation facility (either a highway or bridge) among all vehicle classes using it. The purpose of this dissertation is to study and enhance a model, known as the least-core model, to include both pavement thickness and traffic capacity requirements for all coalitions formed with a given group of vehicle classes. Considering vehicle classes as players and groups of vehicle classes as coalitions, it is possible to quantify the thickness and width of pavement needed to accommodate the vehicle ...


Increasing Accuracy Of Simulation Modeling Via A Dynamic Modeling Approach, Prasanna Rao Venkateswara Rao May 2011

Increasing Accuracy Of Simulation Modeling Via A Dynamic Modeling Approach, Prasanna Rao Venkateswara Rao

Masters Theses

Simulating processes is a valuable tool which provides in-depth knowledge about overall performance of a system and caters valuable insight on improving processes. Current simulation models are developed and run based on the existing business and operations conditions at the time during which the simulation model is developed. Therefore a simulation run over one year will be based on operational and business conditions defined at the beginning of the run. The results of the simulation therefore are unrealistic, as the actual process will be going through dynamic changes during that given year. In essence the simulation model does not have ...
