It is an honor to serve as the next Chair of the Industrial & Manufacturing Systems Engineering Department at UTA. The University and Department are experiencing tremendous growth so the job is even more exciting. This growth opens up many opportunities and challenges for us, ones that I am looking forward to meeting with you.
The academic community is experiencing significant changes. Increased attention on costs, greater competition, and decreasing federal budgets are all putting pressure on us to rethink how we do business. Likewise we also see new technologies, new education models, and an increased interest in science, technology, engineering and mathematics fields. It’s critical that we prepare our faculty, staff and students for the changing educational environment of the 21st century.
I would like to thank Dr. Chen and Dr. Liles for their leadership serving the department over these past years. IMSE has made significant gains under their tenure and this has made my job that much easier!

I came to UT Arlington to pursue my master’s in August 2007 in Industrial Engineering. I was a life-long student having never worked in the industry, so it was not a very big jump to go from B.Tech to a master’s and then on to a Ph.D. which I completed in December 2013. The operations research courses attracted me the most in my master’s, especially the ones taught by Dr. Corley, Dr. Rosenberger, and Dr. Chen. Even though I made some B’s, I had a lot of fun learning some amazing mathematics and statistics.
As a part of my master’s, I undertook research projects under Dr. Jay Rosenberger which gave me my first exposure to Ph.D. level research. The projects were done by previous students in the Center On Stochastic Modeling, Optimization, & Statistics (COSMOS) . My first impression of joining the COSMOS lab was when I peeked through the door and found that Spock from Star Trek was looking straight at me, disapprovingly. I started smiling when I realized it was only a life-sized replica. I was relieved to see that even though I was jumping into some serious research, there was still an element of humor to lighten the somber mood of the lab. Even though, quite frustratingly, when my own lack of knowledge and ignorance was brought into sharp focus, I looked at those times as a great learning opportunity. I worked on a nurse optimization project which was entering the testing stage at HEB hospital. After my master’s, I joined the Ph.D. program as a natural extension to my research work. Around that time, Dr. Anjomani came to Dr. Rosenberger for optimization of urban planning. The problem was to choose which would be the best land use to assign any given land piece. Each land piece would be given a certain rating regarding various land uses, e.g., high residential, low industrial, open areas, etc. It was a simple assignment optimization problem. We tried to use the methodology that was used for nurse optimization for urban planning optimization, but we hit a block which did not allow us to make any progress due to symmetry issues.
Given that we recognized we would not be able to make progress in the research in the direction we were headed, we decided to switch directions. I extended the simple land use optimization problems with more constraints by taking into account urban sprawl. After literature review, I recognized that urban sprawl had a lot of research towards solving it but there were not many comprehensive optimization models. So, the next step was to construct a mathematical model which would address all the various factors contributing towards urban sprawl. After the model was constructed, it was so large that CPLEX, an optimization software, would not even accept the model. It allowed us to experiment with Benders Decomposition method to reduce the model size and allow us to solve the model.
I also worked as a teaching assistant for the IMSE Department when I joined the master’s program. I sincerely enjoyed my time at UT Arlington since it gave me an opportunity to try a variety of things, e.g., salsa, yoga, aikido, etc.
I am currently working as a software engineer for E2open as their optimization specialist.

Some of you may remember Kaushik Gorahava from his time at UT Arlington as a student and a teaching assistant. Below is his reflection on his research and experience at UT Arlington:
I completed my Ph.D. from the Industrial & Manufacturing Systems Engineering department at The University of Texas at Arlington in summer 2013. After having worked as an Industrial Engineer in India’s manufacturing industry for more than three years, I came to the USA in August 2007 to pursue further studies. I completed my M.S. in Industrial Engineering degree in 2009 and took many advanced Statistics, Optimization, and Mathematical Modeling courses in the Industrial Engineering and Mathematics department, respectively.
As a project in the Stochastic Processes course, I reviewed and analyzed a Stochastic Model for using Ring Vaccination for smallpox control. The project was well received in the class and motivated me to pursue further research at the interface of Systems Science and Epidemiology. Under the guidance of my mentors, I developed my broad research area, optimization in neglected public health issues, for my Ph.D. dissertation. In fall 2009, I started my Ph.D. in the Center On Stochastic, Modeling, Optimization, and Statistics (COSMOS) laboratory, under the guidance of Dr. Jay Rosenberger, an expert in Optimization. I was also mentored by my dissertation co-adviser, Dr. Anuj Mubayi, an applied mathematical scientist working at the intersection of epidemiology and social networks.
Being from India, a developing country, I had observed first-hand the suffering caused by disease and poverty. I noticed an urgent need for improvement in public health policies, especially the basic ones. I chose to work on improving one of the basic control measures for a neglected infectious disease, Leishmaniasis, which mostly affects poverty stricken communities and is the second deadliest vector-borne disease in the world. Leishmaniasis spreads to humans by the bite of an infected sandfly. Bihar’s Public Health Department has limited financial resources and can spray insecticide at a limited number of sites. My research aimed to address questions on optimal insecticide allocation for conducting a spray campaign. My dissertation research involved building and analyzing optimization models. The mathematical models were built by considering factors affecting disease transmission and metrics to help the Public Health Department make better decisions. The results of my dissertation study recommended an improved and long-lasting insecticide spray campaign policy for Bihar’s Public Health Department.
I also enjoyed training and teaching individuals, a set of skills which I acquired through my experience as a Teaching Assistant at the Industrial Engineering department during my doctoral studies. During my graduate studies, I mentored some undergraduate and master’s students. I am an independent researcher now and aim to work at the interface of System Dynamics Engineering and Medical Sciences.

The Fall semester came to a cold end as ice and snow blanketed the North Texas area, forcing the University to reschedule many final exams; but the freezing weather didn’t hang around long enough to spoil the College of Engineering Commencement Ceremony on Saturday, December 14 at College Park Center. The new University president, Dr. Vistasp Karbhari, who has a degree in engineering was the guest speaker at the ceremony which was attended by hundreds of families and friends. For all their achievements, the Industrial and Manufacturing Systems Department would also like to congratulate all our graduates on this special occasion. Here is a list of our newest alumni, as published in The Shorthorn:
Ph.D. in Industrial Engineering:
Degrees Conferred Summer 2013
M.S in Engineering Management
M.S. Industrial Engineering
M.S. in Logistics
M.S. in Systems Engineering
B.S. in Industrial Engineering

As this entry goes online, I will be in Minneapolis at the annual INFORMS conference presenting a paper entitled “A Cooperative Dual for the Nash Equilibrium.” The gist of this research is that people can often fare better in competitive situations if they cooperate. However, the more profound implication of the work is that complete cooperation is guaranteed to be possible only between two competitors, not three or more. In other words, there is a mathematical limit to complete cooperation. Apparently, three’s a crowd, like we all knew already. In addition, I will be attending the conference “Learning and the Brain” at Harvard in November. At the INFORMS conference, I will also be working on a Systems Engineering research proposal with Dr. Ferreira.
Dr. Rosenberger, a recent IMSE Ph.D. graduate, and I submitted in August a paper entitled “Constraint Optimal Selection Techniques (COSTs) for Nonnegative Linear Programming Problems” to Optimization Methods and Software about an approach to solve huge, currently unsolvable linear programming problems quickly, as demanded by today’s high-speed, high-tech, ever-accelerating world. Linear programming, as you may remember, is the most widely used computational model in the business and scientific worlds. The method was also the basis of a recently issued patent entitled “System, Method and Apparatus for Allocating Resources by Constraint Selection.”
Finally, I will be headed abroad over the winter break and stop thinking about all this heady stuff. Enjoy your semester.

I am originally from Mexico; I earned my bachelor’s degree in Industrial Engineering at the Instituto Tecnologico de Saltillo and worked in a plastic injection company as a Manufacturing and Project Engineer for over two years. My initial desire was to come to the United States to improve the language; however, in 2007 I was awarded a 60-month scholarship from the Mexican National Council for Science and Technology to study at the University of Texas at Arlington (UTA).
I finished my M.S. in Industrial Engineering in Summer 2008 and pursued a PhD program in Fall 2008, joining the COSMOS (Center on Stochastic Modeling, Optimization, & Statistics) family. My research focused on the study of an advanced statistical method called Multivariate Adaptive Regression Splines (MARS) and the development of variants and sequential algorithms that provide more flexibility to the modeling process and facilitate the optimization routines. The case studies included an inventory forecasting problem, an air pollution problem and an automotive crash safety design problem.
During my graduate studies I was selected as a Graduate Research Assistant at TMAC, where I had the opportunity of being involved in different consulting projects for small and medium companies located in the Dallas/Fort Worth metroplex. Being part of the diverse community of UTA has been absolutely one of the most important experiences in my life not only because of the professional achievements I have earned but also because of the amazing people I have been fortunate to meet.
