Eric North - Undergraduate Student

The Summer Undergraduate Research Fellowship (SURF) program:

Over the past two decades, natural disasters (for example, earthquakes) have grown in number and intensity. These events have led to the destruction of property and in most instances the loss of life with worldwide costs in the hundreds of billions. The key to a rapid recovery from such events is dependent on available resources (where they are located) and a reliable transportation network. Examples of critical resources may be heavy equipment for clearing debris or for helping in the reconstruction of damaged infrastructure (e.g., bridges, powerlines, water lines, etc.), utility repair equipment and materials (e.g., power transformers, cable, conduits, etc.), and much more. As for a reliable transportation network, simply is the road network dependable enough as to allow for the various entities (e.g., utilities, state and federal agencies, etc.) to access their critical resources for the recovery efforts? The decision of where to locate these critical resources as to guarantee that they will be accessible after a disastrous event like an earthquake is very difficult since there is no assurance that the transportation network will remain intact. Hence in this project we propose to develop an optimization model based on discrete location and network flow theory that takes into account two decisions that an entity can make, first where to locate critical resources and second determine the most probable paths between resource locations and impacted destinations as to minimize recovery efforts.

USDA- Green Sustainable design of warehouses/manufacturing and location

Abstract: The increasing reliance on fossil fuels by today’s emerging economies has a profound implication on the sustainability of many warehousing and distribution logistical systems worldwide. Hence, this research attempts to fill the gap in current green warehousing literature by investigating how warehousing and distribution facilities view greener strategies as a way to increase operation efficiency through a stated preference approach, namely and industry survey. A survey instrument was developed and conducted to identify warehousing characteristics, green practices, and current green views of warehouse managers in El Paso, Texas. The survey results found a balanced outlook within the environment and business needs. Companies revealed the importance of investing on the environment, while also improving operational efficiencies and lowering costs, in spite of an economic downturn. Others showed indications of incorporating green strategies for the purpose of benefiting the company, and if these investments are not too costly.

Mouyid B. Islam, PhD (Works for CH2M HILL)



This research aims to analyze large-truck involved crashes (i.e., having a gross vehicle weight rating more than 10,000 pounds) through the application of advanced econometric modeling techniques—namely, random parameter models (i.e., tobit regression, mixed logit). To achieve this, various national and state specific data sets are analyzed with the goal to provide an improved understanding of the complex interactions of contributing factors (e.g., factors related to drivers and occupants, vehicle, and road-environment) influencing large-truck crashes. Additionally, the modeling techniques considered in this research account for possible unobserved effects related to the data. The aforementioned econometric techniques provide an analytical foundation for exploring the contributing factors leading to large-truck involved crashes.

Comparison of EU and US seaport facilities and liner shipping


Maritime trade is the backbone of international trade, specifically seaports which provide the gateway for the shipping and receiving of all international goods. Any disruption in operation can trickle down the global supply chain increasing costs and delay delivery of supplies. Hence, the objective of this work is the formulation of optimization models to study the vulnerability of intercontinental ports. Experiments are applied to container transportation between U.S. and Europe. The work differentiates itself from previous studies in that we analyze the vulnerability of the sea ports and compare how the closing of some ports or liner shipping lanes influence/impact the total supply chain costs for a set of commodities.

A Multimodal Freight Collaborative Hub Location and Network Design Problem


New collaborative technologies have been developed in recent years and they offer potential solutions and opportunities for collaboration among all modes of transportation. Multimodal transportation is the shipment of goods in a single transportation unit. The main factor for the creation of efficient multimodal transportation network is an appropriate location of multimodal facilities and effective routing through existing transportation networks with focus on minimizing the operational costs. This research seeks to understand and develop collaboration models for both rail and highway modes of transportation, referred to as rail-road collaboration, thereby filling a key gap in the current collaborative logistics literature. From an operations research perspective, two models were developed. First, a static multimodal freight collaborative hub location problem (MFCHLP) was addressed to gain insights on effects of multiple commodities on collaborative intermodal transshipment facility locations from a planning perspective. Second, a collaborative freight multimodal fixed charge network design problem (SMMCCP) was also addressed to gain insights on the effects of multiple commodities on multimodal collaborative routing over a fixed network. The aforementioned models provide an analytical foundation for exploring the LTL carrier collaboration paradigm.

Condition Monitoring of Truck-Drivers in the EU and the USA


Road accidents involving trucks cause far-reaching consequences for property as well as human lives in comparison with other accidents. Therefore, it is necessary to create an environment in which truck drivers can safely perform their work and find a way of keeping tired truck drivers off the roads. The goal of this research is to review the required policies and legislation for truck drivers in the EU and the U.S. Based on this review, a comparison analysis of both policies will be performed. A further step will involve the analysis of crash data from the EU and the U.S. A principal focus is labeled at the behavior of drivers and driving conditions. Statistical analyses will be performed on the crash data and inferences will be drawn. This work will also draft recommendations and propose changes in legislation in terms of road safety based on the advantages extracted from both the EU and the U.S.

Collaborative Freight Carrier Systems: Collaborative Hybrid Hub-and-Spoke Networks

Sayten is develped algorithmic approaches to a centralized carrier collaboration multi-hub location problem (CCCMLP) for the small- to medium-sized less-than-truckload (LTL) industry. The CCCMLP represents a strategy in which a central entity (e.g., a third party logistics firm) seeks a set of hybrid collaborative consolidation transshipment hubs to help establish a collaborative hybrid hub-and-spoke system that minimizes that total collaborative costs for the set of collaborating carriers. A carrier has the option to either collaborate or directly ship their respective demand without collaborating. This decision is dependent on the expected profit margin over shipping directly while following a revenue generating rate setting behavior. The CCCMLP is formulated as a variant of the P-hub location problem, which is NP-hard and solved…
