Abstract: This seminar will discuss the pursuit of creative and novel research in the foundations of systems engineering to enable a reimagining of systems engineering. A reimagining is needed due to the growing challenges in costs, schedules, etc. that systems engineering is facing as systems become ever more complex. Specifically two research topics will be discussed: decision making in systems engineering and the art of systems engineering. Decision making is researched in order to reduce inconsistencies in systems engineering by advancing the state of observing, communicating, and representing preferences. Inconsistencies in decision making typically lead to designs that are non-optimal due to stakeholders disagreeing on what is best. Utility and game theories are the primary tools used in this research. The arts are researched to identify approaches that could aid in understanding and performing systems engineering and to infuse those artistic approaches into systems engineering. The arts research that will be discussed in this seminar are gaming, storytelling, and theatre. In particular, the need for a surrogate of complex systems due to the high costs, long durations, and limited accessibility of common complex systems will be discussed, with theatre proposed as a surrogate. The findings of the research demonstrate that systems engineering can be improved, but a fundamental transformation of systems engineering may need to occur for those improvements to be fully realized.

Biography: Dr. Bryan Mesmer is an Assistant Professor in the Department of Industrial and Systems Engineering and Engineering Management at the University of Alabama in Huntsville. Dr. Mesmer was previously a Postdoctoral Research Associate in the Department of Aerospace Engineering at Iowa State University. He completed his Ph.D. in August 2012 at the State University of New York at Buffalo in Mechanical Engineering. Also at the University at Buffalo, he completed his M.S. in Mechanical Engineering (2010) and a dual B.S. in Mechanical and Aerospace Engineering (2007). His research has focused on improving the systems engineering process, particularly for large-scale complex systems. He uses his background in decision analysis, multidisciplinary design analysis and optimization, system/subsystem modeling, design theory, and value-based design to perform research on topics including: interactions in systems and design; incorporation of end-user models and simulations in design; preference representation and communication; the arts in systems engineering; and integration of new system and design processes in government and industry practice. He is currently the University Lead of the NASA Systems Engineering Research Consortium, leading efforts on the development of systems engineering principles and the integration of modelling techniques.

 

 

Scott Wiederhold to Present Seminar

UTA IMSE alumnus Scott Wiederhold from American Airlines will present at the IMSE Seminar on Monday April 23 at 1:15pm in Room 105 of Nedderman Hall. Mr. Wiederhold’s presentation title, abstract, and biographical sketch are below.

0Title: From Mainframes to Machine Learning: Advanced Analytics at American Airlines
Author: Scott Wiederhold
Location: Nedderman Hall (NH) Room 105
Date: Monday, April 23
Time: 1:15pm – 2:15pm

Abstract: Every day at American Airlines over 6,500 flights depart carrying over 500,000 passengers. Planning for every single flight starts almost a year in advance, and requires the input of multiple departments. The Operations Research Team at American Airlines plays a critical role in the models, systems, and analytics that departments across the airline rely on to do their jobs on a daily basis. This talk gives insight into the entire flight and passenger journey – from building a schedule, pricing and selling tickets, airport layouts, and post-travel items. We’ll also discuss how the Operations Research team supports departments across the airline, and how a new team dedicated to Machine Learning and Data Science is advancing the thinking of Artificial Intelligence across the organization.

Biographical sketch: Scott Wiederhold has been with American Airlines for over 17 years. He manages a new team of OR Consultants responsible for workforce analytics and Human Resources. Prior to working in Operations Research he held positions in Airports, Maintenance, Operations Centers, and Headquarters. Scott received his undergraduate degree from the University of California, San Diego, and his MS in Industrial Engineering from the University of Texas at Arlington.

Abstract: A simulation model must be validated, i.e. demonstrated to accurately represent the system it studies, for its results to be reliable. However, simulation validation is a challenging task.  One of the primary sources of this challenge is the absence of an oracle to test its validity, as without an oracle one cannot determine if the result of a program is correct. This oracle problem has long been studied in software engineering. Metamorphic Testing has been found to be an effective technique to test software without an oracle by creating pairs of test cases that act as pseudo-oracles. We provide guidelines on applying a modified version of metamorphic testing to increase confidence in the validity of simulation models. In this technique, pseudo-oracles are developed based on metamorphic relations between parameters and behaviors within an executable simulation model. These relations represent an understood property of the system being studied, which can be used to check the validity of the simulation without knowing the correct answer. In this talk we will explain metamorphic testing and how it applies to simulation model validation, including a demonstration of its effectiveness via a case study on a gossip propagation model.

 

Biographical Sketch: Dr. Megan Olsen is an Associate Professor of Computer Science at Loyola University Maryland. She earned her M.S. (2009) and Ph.D. (2011) in computer science from University of Massachusetts Amherst, and her B.S. in computer science from Virginia Tech (2005). Dr. Olsen’s research currently focuses on improving simulation approaches and validation. Recent work includes quantifying the level of validation achieved on a simulation model, guidelines for using metamorphic testing for simulation validation, and utilizing reinforcement learning within agent-based predator-prey models. Recent work has been published in Summer Sim, Winter Sim, Spring Sim, and the International Conference on Computational Science.
