Generalized Relay Network Design And Collaborative Dispatching In Truckload Transportation, Amin Ziaeifar Oct 2019

Generalized Relay Network Design And Collaborative Dispatching In Truckload Transportation, Amin Ziaeifar

Operations Research and Engineering Management Theses and Dissertations

The truckload industry faces a serious problem of high driver shortage and turnover rate which is typically around 100\%. Among the major causes of this problem are extended on-the-road times where drivers handle several truckload pickup and deliveries successively; non-regular schedules and get-home rates; and low utilization of drivers dedicated time. These are by-and-large consequences of the driver-to-load dispatching method, which is based on point-to-point dispatching or direct shipment from origin-to-destination, commonly employed in the industry. In this dissertation, we consider an alternative dispatching method that necessitates careful design of an underlying network. In this scheme, a truckload on its …

Equilibrium-Based Workload Balancing For Robust Emergency Response Operations In Metropolitan Areas, Parya Roustaee Apr 2019

Equilibrium-Based Workload Balancing For Robust Emergency Response Operations In Metropolitan Areas, Parya Roustaee

Civil and Environmental Engineering Theses and Dissertations

This thesis presents an equilibrium-based modeling framework for emergency response (ER) workload balancing to achieve robust operation in large-scale metropolitan areas. The problem is formulated as a non-linear mathematical program (NLP), which determines the optimal workload cutoff for each ER station such that the weighted sum of the area-wide expected response time and its variation are minimized. The concept of Marginal Cost of Uncertainty (MCU) is introduced to measure the impact of a station’s workload increase on the area-wide service performance. The solution of the NLP is proved to be equivalent to a state of equilibrium in which all stations …


Behavior Of Geothermal Energy Piles Embedded In Rock, Ehab Sabi Apr 2019

Behavior Of Geothermal Energy Piles Embedded In Rock, Ehab Sabi

Civil and Environmental Engineering Theses and Dissertations

Geothermal energy piles are categorized as closed systems. Energy piles are a relatively new technology which couples the structural role of traditional pile foundations to that of heat exchangers to fulfill the required energy demand of buildings and infrastructures. These foundations are equipped with pipes embedded in the concrete forming the pile. While connected to a heat pump, the fluid circulating inside these pipes provides the exchange of heat with the ground for heating and cooling purposes. As the undisturbed temperature at the shallower depths of the ground stays comparatively constant the whole year, being warmer than the surrounding temperature …

Congestion Mitigation Strategy: Modeling The Effect Of Different Geometric Configurations Of A Two-Lane On-Ramp On Capacity Using Vissim, Rhizlane Brachmi

ETD Archive

Freeway on-ramps are critical components of freeway systems since they control the entry of traffic to the mainline. According to the Highway Capacity Manual (HCM), a two-lane on-ramp configuration will achieve less turbulence than a similar one-lane on-ramp but little guidance on the desired lengths of the acceleration lanes or their effect on the operation of the influence area is provided. An experiment was designed to investigate the effect of the lengths of the acceleration lanes of isolated, two-lane on-ramps on the operation of the ramp influence area. The Highway Capacity Software (HCS) was used to calculate the density of …

Investigation Of Dredge Material Dewatering Through Hydraulic And Ground Improvement Methods, Monica Moody Jan 2019

Investigation Of Dredge Material Dewatering Through Hydraulic And Ground Improvement Methods, Monica Moody

Williams Honors College, Honors Research Projects

Every year almost 1.5 million tons of material is dredged from Lake Erie to allow passage for boat traffic. In the past, this material has been placed back into the open waters of the lake. However, starting July 2020 this will no long be permitted due to the passing of Senate Bill 1. Therefore, secondary uses of this dredging material are being investigated. To be used, the material needs to be quickly dewatered and stabilized. This project consists of literary reviews of two methods of rapid dewatering, hydraulic placement and ground improvement methods. Hydraulic placement dewatering requires the use of …

Effect Of Continuity Plate Eccentricity On The Performance Of Welded Beam-To-Column Connections, Jason Thomas Norwood Dec 2018

Effect Of Continuity Plate Eccentricity On The Performance Of Welded Beam-To-Column Connections, Jason Thomas Norwood

Graduate Theses and Dissertations

Beam-to-column connections in structural steel buildings may have varying degrees of rotational restraint and varying degrees of moment transfer. In fully restrained moment connections, shear is typically transferred through the beam web, while the moment is mostly transferred through the beam flanges which create tension/compression force couples. Column sections that are incapable of resisting these flange forces are often retrofitted with continuity plates within the connection region to improve capacity. In cases of unequal beam depths on either side of the column, an eccentricity between the framed-in beam flange and continuity plate may be required; however, limited research exists to …
