Title:  Commercial Aircraft Passenger Boarding Model

Speaker: Dr. Flanigan

Date: Wednesday, July 13, 2016 @ 6:30PM

Location: Arlington Central Library, 1015 N Quincy St, Arlington, VA (1st floor auditorium)

Schedule: Networking and refreshments from 6:30 to 7:00, talk from 7:00 to 8:00 with Q&A

Abstract: Commercial aircraft have numerous passenger boarding strategies to optimize the boarding time that often cause delays in airports across the world.  These strategies are modeled to identify which one provides the best overall boarding time.  The passenger boarding model methodology is presented to describe the variables and factors considered while developing the baseline model, in addition to comparing the results with available boarding data.  By developing this baseline model, we may then explore the concept a biometric exit tracking system that will scan the outgoing passengers’ biometric features prior to boarding the plane, and evaluate the impact to airline boarding times.  This model is extended to conduct additional analysis to evaluate the passenger growing (or decreasing) satisfaction dependent on which boarding strategy is used.

Bio: Dr. Flanigan supports multiple government sponsors in the early stage systems engineering phases of development. In this position, he often works within an integrated product team structure with government, industry, and academia organizations to plan and execute analytical studies in support of advanced concepts and integrated acquisition strategies. Before arriving at The Johns Hopkins University Applied Physics Laboratory (JHU/APL), Dr. Flanigan was a Surface Warfare Officer onboard two AEGIS cruisers and was stationed in Washington, DC.  He retired from the U.S. Navy after 20 years of active and reserve service.  Dr. Flanigan holds the following degrees: B.S. in Physics from the University of Arizona; M.S. in Information Systems and Technology from the Johns Hopkins University; M.S. in Systems Engineering from the Johns Hopkins University, and a Ph.D. in Systems Engineering and Operations Research from George Mason University.  Dr. Flanigan is the vice chair of the Systems Engineering Program for the Johns Hopkins University Engineering for Professionals.  Dr. Flanigan is a member of INCOSE, INFORMS, and MORS.

What do coin tosses, decision making under uncertainty and vessel traffic risk assessment have in common?

Speaker: Dr. J. Rene van Dorp

Date: Tuesday, March 29th, 2016

Location: GW University – Science & Engineering Hall, Room B1220 - Lehman Auditorium (Lower Level), 800 22nd St NW Washington, DC 20052

Abstract:  Is it safer for a river gambling boat in New Orleans to be underway than to be dockside? Should wind restrictions for outbound tankers at Hinchinbrook Entrance in the Prince William Sound Alaska be lowered from 40 knots to 35 knots? Is investment in additional life craft on board Washington State Ferries in Seattle warranted or should the International Safety Management (ISM) code be implemented fleet wide? Can enhanced ferry service in San Francisco Bay and surrounding waters alleviate traffic congestion on roadways in a safe manner? Do potential traffic increases made possible through the addition of a pier terminal at a refinery located north of the San Juan Islands in Washington State increase or reduce oil transportation risk? The risk management questions above were raised in a series of projects over a time frame spanning more than 20 years and were addressed using a single risk management analysis methodology developed over the course of these projects by a consortium of universities. This methodology centers around dynamic maritime risk simulations of Maritime Transportation Systems (MTS) that also integrate incident/accident data collection, expert judgment elicitation and consequence models. Via a coin toss argument we will advocate decision making under uncertainty in this context to be informed by relative risk comparisons by highlighting the analogy of an potential accident with the toss of a biased coin. An overview of the most recent Vessel Traffic Risk Assessment 2010 (VTRA 2010) shall be presented.

Bio:  J. Rene van Dorp has been exposed to multiple projects assisting organizations in making structured decisions involving complex systems, specializing in risk and reliability problems. His research has resulted so far in 44 refereed journal publications, 17 conference proceedings, 1 book, 4 book chapters and 19 technical reports. General themes have been the development of formal methods integrating expert judgment, distribution theory, available data and Monte Carlo Methods, specifically, Markov Chain Monte Carlo Methods, Monte Carlo Integration for Uncertainty Analysis and Maritime Traffic Simulation. Clients include Puget Sound Partnership, Makah Indian Tribe, BP, the San Francisco Bay Water Transit Authority, Washington State Department of Transportation; Prince William Sound Shipping Companies; United States Coast Guard; United States Air Force; a Dutch dredging company (HAM); The National Aerospace Laboratory in Amsterdam and a Dutch Chemical Multinational DSM. His responsibilities ranged from organizing and overseeing data analysis efforts; developing, validating and integrating various mathematical/statistical models to creating presentations/reports describing technical findings in ways for both experts and lay persons. The success of these projects depended to a large extent on the successful integration and coordination of the work of a team of analysts/ researchers. Research domains of special interest to J. Rene van Dorp include Maritime Risk Management Analysis, Probabilistic Risk Assessment, Reliability Analysis, Uncertainty Analysis, Health Care Management Science and Distribution Theory.

Where Science Meets Practice: OR in Cyber

Speaker: Dr. Julie Ryan

Date: Thursday, January 14th, 2016 @ 6:30 PM

Location: George Washington University: Science & Engineering Hall, Room B1220 - Lehman Auditorium, 800 22nd St NW Washington, DC 20052

Abstract:  The fields of cyber-whatever have exploded in the past decade.  Cyber-security, cyber-warfare, cyber-operations, etc. have etched a presence on the military structure.  And yet, much of cyber is as much art as it is science, particularly in the areas of cyber-warfare, both defensive and offensive.  This is an expected situation, given the maturity of cyber.  In this presentation, the areas in which OR can contribute to the development of robust and effective cyber capabilities will be explored.  A strategy for moving forward will be suggested based on historical lessons learned.

Bio:  Dr. Julie Ryan has been working in the field of information security for over 30 years.  Starting out as an intelligence officer in the US Air Force, she has tackled problems in the military, in government, in industry, and in academia.  Currently, she is Associate Professor of Engineering Management and Systems Engineering at the George Washington University, located in downtown Washington, D.C., where she teaches and directs research in information security, cyberwarfare, systems dynamics, and analytics.  Her books include “Defending Your Digital Assets Against Hackers, Crackers, Spies and Thieves” (McGraw-Hill 2000), “Leading Issues in Information Warfare and Security” (API 2011), and “Detecting and Combating Malicious Email” (Elsevier 2014).  Her degrees include B.S. from the U.S. Air Force Academy, MLS from Eastern Michigan University, and D.Sc. from George Washington University.
