The Capstone Design Expo returned to McCamish Pavilion on December 7, 2021, for the first time since the fall of 2019. Many of the participants were in-person, but teams also included online representatives who were available to talk to online judges from all over the world. Of the 118 teams participating, 23 teams were from the H. Milton Stewart School of Industrial and Systems Engineering (ISyE).

“It was wonderful to see the senior design students develop and present their projects in person. They endured another stressful semester, but remarkably balanced quality and rigor with health and wellbeing,” said Director of Professional Practice Dima Nazzal. “Kudos to them for overcoming the challenges and delivering excellent work for a wide range of clients including government agencies, small non-profits, and large corporations. Congratulations to the faculty advisors, who coached the teams and kept them motivated and focused. A special recognition and appreciation to our Director of Technical Communication, Brandy Blake, for teaching the students how to communicate their engineering designs clearly and succinctly”

Senior Design team “Provision with a Vision” won the Capstone Expo award for Best ISyE Project. They worked with the on-board services group at Delta Air Lines to develop a data-driven methodology that determines the optimal amount of beverage items to load on a flight. The project motivation came from unused items adding extra weight to the aircraft resulting in excess fuel costs and carbon emissions. The team delivered an optimization model that takes into consideration passenger demand as well as an impact analysis tool which allows Delta to visualize how small changes in beverage quantities can have significant economic and environmental impact across the system.

The team included Anneliese Conrad, Carolina Howell, Niral Jagtap, Ellie Johnson, Nico Knutzen, Sofia Laval, Brad Peterson, and Libbee Stallone. They were advised by Associate Professor Anton Kleywegt.

From among the ISyE teams, three were selected as finalists for the Best of ISyE Senior Design Competition, which was held on December 14, 2021. Team “Shoulda Put A R(INGO)n i(T)” was selected as the first-place winner.

Team “Shoulda Put A R(INGO)n i(T)” partnered with Novelis, an aluminum manufacturing company, to improve ingot availability in its Oswego, NY, facility. The goal of the project was to ensure that when a customer makes an order, Novelis could supply the right ingots at the right time on hand to immediately start production. The team’s solution was to build an ingot “supermarket” that would increase ingot availability from 50% to 90% and reduce overall lead time by up to 40%. To achieve this, the team created an optimization model that recommended the best replenishment strategy for each ingot SKU and used a simulation model to measure the impact of the supermarket on the production process. With this new tool, Novelis can dramatically increase their operational efficiency and save millions of dollars per year.

Team Members included Tobin Abraham, Joseph Abrokwa, Elvin Chirackal, Joseph Cochran, Lorenzo Guerrero, Grace Anne Muller, and Tim Ryan. They were advised by Part-Time Lecturer and Tennenbaum Institute Principal Research Engineer Douglas Bodner.

Finalist team “Can’t Stop, Won’t Stop, Bus Stop” worked with the Atlanta Department of Transportation (ATLDOT), a recently formed government entity tasked with promoting transportation infrastructure. The team worked to provide ATLDOT with a data-driven methodology to allocate funding to bus stop improvements and a platform for closer collaboration with MARTA. Only 7% of bus stops (out of nearly 4,000) in Atlanta have shelters, which provide riders with proper seating, protection from weather, and ADA accessibility. The team’s solution combines process design with an interactive web tool and a greedy heuristic web app. Through the team’s solution, an additional 1.5 million trips per year will now originate at a sheltered stop. The City of Atlanta voted to back the project with a $3.4 million non-fungible funding source, and the team will present their design to the new mayor in January.

Team members included Soobin Baek, Aaron Brown, Ananya Ghose, Sanghwa Lee, Sung Kyu Lee, Alea Legg, Hetu Patel, Tejas Santanam. They were advised by ISyE Lecturer Gamze Tokol-Goldsman.

Finalist team “Keep it Simply” worked with The Coca-Cola Company to minimize the overall cost of the distribution network of two recently acquired dairy brands: Fairlife and Simply Oat & Almond. The team provided a data-driven method of formulating network expansion plans and determining safety stock levels by building and validating a mathematical optimization model that recommends not only the optimal distribution center (DC) opening location and timeline, but also the capacity expansion and safety stock level at each DC over a given horizon. This provided an annual value of several million dollars across the two dairy brands. To help Coca-Cola design the network expansion of any brand in the future, the team generalized the model to a standardized template wrapped within a user-friendly graphical user interface with three different model options.

Team Members included Joseph Chanin, Yizhi Huang, Minrui Liang, Yufei Liu, Naren Reddy, Xinran Yu, and Emily Zhang. They were advised by Leo and Louise Benatar Early Career Professor and Associate Professor Alejandro Toriello.

In addition, two teams received honorable mentions and were contenders for the Best of ISyE Senior Design.

Team “Panic! at the Cisco” worked with Cisco on its Printed Circuit Board Assembly Component Allocation. Team Members included Anjana Anandkumar, Udisha Bhattacharyya, Grace Gilpatric, Katie Landers, Kat Pospichel, Briana Sims, Tan Tanthien, and Anna (Tu) Vu. They were advised by William W. George Chair and Professor Pinar Keskinocak.

Team “The Bee’s Knees” worked with Smith + Nephew on its production planning. Team Members included Leon Breaux, Sara Costello, Emma Jones, James McGregor, Georgia Warnock, and Delaney Wastler. They were advised by ISyE Lecturer Ethan Lee.
