Advancing Transportation Routing Decisions Using Riemannian Manifold Surfaces, Emre Tokgöz, Iddrisu Awudu, Saravanan Kuppusamy

Rohrer College of Business Departmental Research

We consider several real-world driving factors such as the time spent at traffic signs (e.g., yield signs and stop signs), speed limits, and the topology of the surface to develop realistic and accurate routing solutions. Though these factors increase the complexity of modeling, they provide the flexibility to evaluate the routing solutions from different perspectives: cost, distance, and time, to name a few. First, we develop a set of algorithms based on the Riemannian manifold surface (RMS) to factor in the Earth’s curvature to calculate distances. Second, we present a multiobjective, nonlinear, mixed-integer model (MINLP) that minimizes the distance traveled, …

Change Management In Construction: Necessity, Obstacles,And Suggested Solutions, Ihab M. H. Saad

The Professional Constructor

The construction industry is one of the major harbingers of the economy of any industrialized nation. Its contribution to the Gross Domestic Product is undeniable. The major economic downturn that lasted from 2008 to 2011 resulted in a lot of change in the industry personnel at both the administration and labor force levels. This resulted in expediting the retirement of a generation of seasoned professionals, and creating a gap in the ranks of construction firms that is still to be completely filled. Similar impacts followed the uncertainty resulting recently from Covid-19 and the economic instability and uncertainty it caused. One …

Pert, Cpm And The Tangled History Of Network Scheduling, Charles Christopher Smith, Vivek Sharma, Gregory B. Baecher

The Professional Constructor

The origins of two network scheduling techniques: The Program Evaluation Review Technique (PERT); and the Critical Path Method (CPM) are examined.

Transportation project owners are often concerned with the risks associated with construction, because these challenges can directly affect project outcomes and often lead to increased time and cost for projects. It is, therefore, vital to identify challenges early within the project life cycle. Transportation project delivery has evolved to strengthen the influence that the owner has upon the project, transitioning away from the exclusive use of traditional Design-Bid-Build to the more innovative and involved approaches of Design-Build and Construction Manager / General Contractor. Unfortunately, this has resulted in increased owner risk. In this research, transportation project owners were asked to …

A Culture-Based Analysis Of Construction Management Students’ Conflict Management Styles, David W. Martin

The Professional Constructor

The use of collaborative project delivery systems in the construction industry requires cooperation and shared management of the construction process to achieve success. This growth in collaborative systems requires project representatives to effectively manage conflict. Project failures utilizing collaborative methods are frequently attributed to an inability of project representatives to collaboratively resolve conflict. Research suggests that minorities are prone to use a collaborative conflict management style and the inclusion of minorities in construction management (CM) roles can reduce negative conflict. The growing evidence that increasing workforce diversity in CM is beneficial to the industry indicates that there is value in …

A Framework For Adaptive Capacity In Complex Systems, Abdulrahman Alfaqiri

Engineering Management & Systems Engineering Theses & Dissertations

Complex systems are characterized by their high level of inter-connectivity, ambiguity, and emergence. Therefore, a failure in one element of a system (e.g. cyber layer) due to external or internal disturbances can lead to a cascade effect that may influence all elements of the system. Consequently, the complex system will not be able to perform its functional performance. Threats related to complex systems are very dynamic, fast, complex and damage can be severe. Thus, to respond to the dynamic and unpredictable nature of these threats, complex systems need to be highly adaptive to survive and thrive in the face of …

A Machine Learning Approach To Delineating Neighborhoods From Geocoded Appraisal Data, Rao Hamza Ali, Josh Graves, Stanley Wu, Jenny Lee, Erik Linstead

Engineering Faculty Articles and Research

Identification of neighborhoods is an important, financially-driven topic in real estate. It is known that the real estate industry uses ZIP (postal) codes and Census tracts as a source of land demarcation to categorize properties with respect to their price. These demarcated boundaries are static and are inflexible to the shift in the real estate market and fail to represent its dynamics, such as in the case of an up-and-coming residential project. Delineated neighborhoods are also used in socioeconomic and demographic analyses where statistics are computed at a neighborhood level. Current practices of delineating neighborhoods have mostly ignored the information …
