Fleet Sizing and Service Region Partitioning for Same-Day Delivery Systems

Many existing Same-Day Delivery (SDD) studies focus primarily on operational dispatch problems and do not consider system design questions. Furthermore, prior work on SDD system design does not consider the fleet sizing decision when a service region may be partitioned into zones dedicated to individual vehicles (such designs have been shown to improve system efficiency in related vehicle routing settings). Banerjee's research utilizes a novel approach to addressing two key tactical design challenges when planning an SDD system: figuring out how many delivery vehicles you need and dividing the delivery area into manageable zones.

Using continuous approximations to capture average-case operational behavior, the problem of independently maximizing the area of a single-vehicle delivery zone is considered first. The approach then characterizes area-maximizing dispatching policies and leverages the results to develop a procedure for calculating optimal areas as a function of a zone's distance from the depot, given a maximum number of daily dispatches per vehicle. Using minimal computation, the approach specifies fleet sizes and builds vehicle delivery zones that meet operational requirements, verified by simulation results.

Electric Vehicle Fleet and Charging Infrastructure Planning

Varma's research focuses on finding the best way to dispatch electric vehicles to pick up customers while making sure they charge periodically. As customer requests arrive, system operators must determine the minimum number of vehicles and chargers for a given service level, along with a matching and charging policy that maximizes that service level. Varma's approach provides a sharp characterization of the fleet size and the charging infrastructure requirements as demand grows. The research highlights the fundamental differences between planning for an electric vehicle system and a gas-powered system. To understand the difference, note that serving a customer comprises two steps -  pickup and trip, each contributing to the fleet size requirement of the system. As EVs require charging time, they need more vehicles to compensate for the trip part of the service. In turn, the optimal dispatching policy can reduce the EV requirement induced by the pick up part of the service by lowering the pickup times, owing to the extra EVs due to the trip phase. The reduction in the EV requirement depends on the number of charging stations and the size of the EV battery packs. 

The research proposes the "Power-of-d" dispatching policy, which achieves this performance by selecting the d closest vehicles to a trip request and choosing the one with the highest battery level. Varma also conducted detailed simulations that verified the scaling results. The paper discusses how the results extend to accommodate demand that increases/decreases repetitively or cyclically over time.

For the 10th Demo Day, the Tech community came out in droves to support 75 Georgia Tech startups created by students, alumni, and faculty. In booths spread out in Exhibition Hall, they displayed their products, which ranged from AI and robotic training gear to fungi fashion, and more. Over four hours, more than 1,500 people filed in and out of the hall. Founders pitched their innovations to business and community leaders, as well as students and the public, eager to witness groundbreaking innovations across various industries.

Kiandra Peart, co-founder of Reinvend, said the amount of people surprised her.

“After the first VIP session was over, hundreds of people were just flooding through the door at all times,” she said. “We had to give the pitch a million times to explain it to a lot of different people, but they seemed really, really engaged, and we were also able to get a few interactions.”

Reinvend is working through a potential deal with Tech Dining on using their vending machines, which would expand food options for students after dining halls close.

Demo Day is the culmination of the 12-week summer accelerator, Startup Launch, where founders learn about entrepreneurship and build out their businesses with the support of mentors. Along with guidance from experts in business, teams receive $5,000 in optional funding and $30,000 of in-kind services. This year, the program had over 100 startups and 250 founders, continuing the growth trend for CREATE-X. The program aims to eventually support the launch of 300 startups per year.

Peart said the experience taught the team how to better pitch to potential clients and formulate a call to action after a successful interaction.

Since its inception in 2014, CREATE-X has had more than 5,000 participate in their programming, which is segmented in three areas: Learn, Make, and Launch. Besides providing resources, the program also helps founders through its rich entrepreneurial ecosystem.

“We want to increase access to entrepreneurship. That’s the heart of the program, and it’s the goal to have everyone in the Tech community to have entrepreneurial confidence. The energy and passion of our founders to solve real-world problems — it’s palpable at Demo Day. I’d say it’s the best place to see what we’re about and understand what this program offers,” said Rahul Saxena, director of CREATE-X, who also reminded founders that the connections they make here would last for years.

At its core, CREATE-X is a community geared toward innovation. Participants were at the forefront of integrating OpenAI's GPT-3 when it was not yet widely adopted. They share their insights with each other, and the program has mentors coming back from even the very first cohort. Starting with eight teams, CREATE-X has now launched more than 400 startup teams, with founders representing 38 academic majors. Its total startup portfolio valuation is above $1.9 billion.

Peart compared CREATE-X to an energy drink.

“After going through the program, I was really able to refine my ideas, talk with other people, and now that the program is over, I feel energized,” she said. “I think that having an accelerator right at home allows students who may have never considered starting a company, or didn't have access to an accelerator, to actually utilize their resources from their school and their own community to get their companies started.”

Although Demo Day just ended, CREATE-X is already gearing up for  the next cohort. Applications for Startup Launch opened Aug. 31, the same day as Demo Day.

“Consider interning for yourself next summer,” said Saxena. “We know you have ideas about solutions to address global challenges. You’re at Tech; you have the talent. Let us help you with the resources and support system.”

Georgia Tech students, alumni, and faculty can apply to GT Startup Launch now. The priority deadline is Nov. 6. To learn more about CREATE-X, find CREATE-X events to build a startup team, or learn more about entrepreneurship, visit th CREATE-X website

In front of a standing-room-only crowd inside the John Lewis Student Center's Atlantic Theater, global leaders from the Hyundai Motor Group and Georgia Tech signed a memorandum of understanding, creating a transformative partnership focused on sustainable mobility, the hydrogen economy, and workforce development.  

As the automaker continues to construct its Metaplant America site in Bryan County — the cornerstone of Hyundai's $12 billion investment into electric vehicles and battery production across the state of Georgia — today's signing ceremony symbolizes the vision that Hyundai and Georgia Tech share on the road to advancing technology and improving the human condition. 

"As a leading public technological research university, we believe we have the opportunity and the responsibility to serve society, and that technology and the science and policy that support it must change our world for the better. These are responsibilities and challenges that we boldly accept. And we know we can't get there alone. On the contrary, we need travel partners, like-minded innovators, and partners with whom we can go farther, and today's partnership with Hyundai is a perfect example of what that means," Georgia Tech President Ángel Cabrera said.  

The state of Georgia and the Institute have positioned themselves as leaders in the electrification of the automotive industry. Hyundai is among the top sellers of electric vehicles in the United States as the company aims to produce up to 500,000 vehicles annually at the $7 billion Savannah plant when production begins in 2025. The plant will create 8,500 jobs, and the company's total investments are projected to inject tens of billions of dollars into the state economy while spurring the creation of up to 40,000 jobs.  

"It's clear, we are in the right place with the right partners," Jay Chang, president and CEO of Hyundai Motor Company, said. "When our executive chairman first decided on [the site of] the metaplant, one of the first things he said was, 'Make sure we collaborate with Georgia Tech.’ Hyundai and Georgia Tech have a lot in common. We have proud histories. We celebrate excellence, and we have very high standards. What we love about Georgia Tech is the vision to be a leading research university that addresses global challenges and develops exceptional leaders from all backgrounds."  

Spearheading new opportunities for students, the partnership will create technical training and leadership development programming for Hyundai employees and initiate engagement activities to stimulate interest in STEM degrees among students. 

José Muñoz, president and global COO of Hyundai Motor Company and president and CEO of Hyundai and Genesis Motor North America, says the company quickly realized the potential impact of the newly forged partnership with Georgia Tech.  

"Proximity to institutions like Georgia Tech was one of the many reasons Hyundai selected Georgia for our new EV manufacturing facility. Imagine zero-emissions, hydrogen-powered vehicles here on campus, advanced air mobility shuttling people to Hartsfield-Jackson Atlanta International Airport, or riding hands-free and stress-free in autonomous vehicles during rush hour on I-75 and I-85. Together, Georgia Tech and Hyundai have the resources to fundamentally improve how people and goods move," he said. 

In pursuit of sustainability, Hyundai has invested heavily in the potential of hydrogen and plans to lean on the Institute's expertise to explore the potential of the alternative fuel source, primarily for commercial vehicles. Hyundai has deployed its hydrogen-powered XCIENT rigs to transport materials in five countries. 

University System of Georgia Chancellor Sonny Perdue was on hand for Tuesday’s ceremony. Reflecting on his visits to the company's global headquarters in South Korea prior to the construction of the West Point, Georgia, Kia plant, he praised the company's values and world-class engineering ability.    

"This is a relationship built on mutual trust and respect. It's a company, a family atmosphere, and a culture that I respect and admire for the way they do business and honor progress, innovation, and creativity. That is why I am so excited about this partnership between the Hyundai Motor Group and the Georgia Institute of Technology because that will only enhance that," Perdue said. 

Owned by Hyundai, Kia recently invested an additional $200 million into its West Point facility to prepare for the production of the all-electric 2024 EV9 SUV. The plant currently manufactures more than 40% of all Kia models sold in the U.S.  

The partnership also includes field-naming recognition at Bobby Dodd Stadium, which is now known as Bobby Dodd Stadium at Hyundai Field, and provides student-athletes and teams with the resources needed to compete at the highest levels, both athletically and academically.

“A stitch in time saves nine,” goes the old saying. For a company in Georgia, that adage became very real when damage to a key piece of machinery threatened its operation. The group helping with the stitch in time was the Georgia Manufacturing Extension Partnership (GaMEP), a program of Georgia Tech's Enterprise Innovation Institute that — for more than 60 years — has been helping small- to medium-sized manufacturers in Georgia stay competitive and grow, boosting economic development across the state.

Silon US, a Peachtree City manufacturer that designs and produces engineered compounds used to create a wide range of products — from automotive applications to building materials, such as PEX piping and wire and cable, was experiencing problems with their extrusion line during a time of increasing customer demand. Problems with the drive mechanism on that extrusion line, a piece of equipment critical to the company’s ability to produce, threatened to shut them down. With replacement parts several weeks away, was it safe to continue operating? At what throughput rates? How much collateral damage might be incurred if they continued to operate?

That’s when Silon managers turned to GaMEP for help.

After working through ideas with GaMEP’s manufacturing experts, the team installed wireless condition monitoring sensors that provide continuous, real-time insights on their manufacturing assets’ health. With the sensors, Silon was able to find a sweet spot that not only allowed them to continue operating but also kept them from overexerting the equipment, preventing further damage.

The solution to that problem has now become a routine part of Silon’s process, as company technicians continue to use this sensor technology for early detection of any deviations or anomalies in the machinery’s health, allowing the company’s maintenance team to proactively respond by adjusting scheduled maintenance to avoid costly downtime.

GaMEP’s Sean Madhavaraman says, “Silon is more productive than ever and on track for growth. The strong results in this challenge are a great example of the decades-long focus of GaMEP to educate and train managers and employees in best practices, to develop and implement the latest technology, and to work together with businesses to find solutions.”

Daniel Raubenheimer and Matt Gammon, Silon’s general managers, also lauded GaMEP, saying, “GaMEP’s extensive experience within the manufacturing realm has been a great benefit to our company. The wireless condition monitoring sensors allow us to predict future breakdowns and mitigate a potential catastrophe — allowing us to operate in a safe manner, while saving money, time, and effort.”

CREATE-X’s Startup Launch will introduce its 10th cohort of talented startup founders on Demo Day, Aug. 31, 5 – 7p.m., in the Exhibition Hall. Last year, the event drew more than 1,500 people, including business and community leaders, to view new products from a wide range of industries. All of the startups are developed through the creative work of Georgia Tech’s faculty, alumni, and students. With these products, CREATE-X founders aim to address global problems head-on with the latest technology and ingenuity.

 

At the event, attendees will be able to explore the products of over 100 newly minted startups, from consumer apps to deep tech, and engage with more than 250 founders about their entrepreneurial journeys. In 2021, CREATE-X startups were at the frontier of the current AI revolution, integrating OpenAI's GPT-3 well ahead of mainstream adoption.

 

CREATE-X began in 2014 as a Georgia Tech initiative to instill entrepreneurial confidence in students launching real startups. Their signature program is the 12-week Startup Launch accelerator, in which students and alumni intern for their own companies. Participants attend sessions, team socials, and pitch practices and receive coaching and mentorship from experienced entrepreneurs and notable Tech alumni. Demo Day is the finale of the program, a vibrant exhibition that is free and open to the public.

 

The inaugural cohort had eight teams. Several companies among the first six cohorts are valued above $100 million, and one company is valued at $1.3 billion. The program has worked with nearly 450 startup teams, with a total portfolio valuation of over $1.9 billion, and has produced more than 1,100 founders launching startups. In the future, CREATE-X Director Rahul Saxena said the program hopes to produce 300 startups a year.

 

“CREATE-X has a rich entrepreneurial ecosystem that will support students as they launch real startups. In every cohort, I remind participants that the connections they make in the program will carry after, and that they’re surrounded by talent,” Saxena said. “We want every Georgia Tech student to have this advantage when starting their business.”

 

He noted, “From consumer apps revolutionizing everyday life to sustainable fashion brands paving the way toward responsible consumption — there's something here for everyone. CREATE-X founders are a testament to tomorrow’s possibilities, and we invite you to see it for yourself.”

 

Registration is open now for Demo Day 2023. For more information, visit the CREATE-X website.
