Interning with American Tire Distributors Advanced Analytics Center of Excellence

American Tire Distributors (ATD) is one of the largest independent suppliers of tires to the replacement tire market. Through our rapid distribution network, with unrivaled sales specialists, an industry-leading digital platform, and robust data analytic capabilities, we’re connecting our customers to the road ahead.

We launched our Advanced Analytics Center of Excellence (AACoE) to disrupt and revolutionize the replacement tire industry through better usage of data and analytics. Our team of analytics experts are finding creative ways to leverage 80-years’ worth of data to its fullest extent. Through the application of artificial intelligence, big data and cloud computing, our AACoE is able to deliver award-winning platforms to drive business results.

 

Being one the largest independent supplier of tires to the replacement tire market, ATD isn’t typically a top employer that comes to mind (yet) to those studying computer science. Our AACoE is changing that, one algorithm at a time. Shreya is a senior computer science major at UNC Chapel Hill, has helped organize North Carolina’s largest hackathon, HackNC, and has recently completed a summer internship with our AACoE. We’re excited for Shreya to share her journey.

ATD’s Bill Williams, Chief Financial Officer and Ravishankar Sivasubramaniam, Senior Machine-Learning Solutions Architect present Shreya with a certificate on completing the ATD Advanced Analytics Center of Excellence internship program.

When I was searching for a summer internship, the last place I would have thought to intern with was a tire distribution company. But that’s exactly where I found myself this summer. When I was accepted into the internship program, I was excited, but nervous. The internship promised the ability to complete a project from development to deployment, but I thought this might be too good to be true. I was unsure if this promise would devolve into just basic data entry, which is every computer science intern’s worst nightmare.

When I arrived at ATD, I didn’t feel like an intern, I felt like a valued member of the analytics team. The first thing I noticed was that the AACoE operates like a cutting-edge startup in the valley, who is on the verge of the next great industry-revolutionizing platform. I was ecstatic to find out that the promise of being able to complete a project from development to deployment was very much real! I was handed a project that had the whole package and I couldn’t wait to get started. The project was to analyze the usage of internal tools across the company and build a dashboard that displayed various trends.

This dashboard was to be used across the business for various leaders. This wasn’t a sandbox project, but a project that impacted the way ATD did business. I was able to meet with the leaders who would be the end users of the dashboard I was responsible for deploying. This allowed me to truly understand the business, get a better idea of how the leaders were going to use the dashboard and allow me to implement an interactive user interface that would benefit ATD.

When developing the user interface, I learned how to make a lightweight web app with Python and Flask. I wrote SQL queries into their databases, experimented with data frames and Plot.ly’s syntax, in order to create charts and then brought the dashboard all together with some Jinja2 in the front end. I built a data pipeline that moved Google Cloud’s billing data to Cloud SQL. I added in charts that broke down what services the AACoE were paying for, contrasting with the charts of actual usage of internal tools built on those services.

 

Shreya presenting the final project to members of ATD

After the dashboard was built, I had the opportunity to deploy and demo it to ATD’s Chief Financial Officer. I was very confident in my project because throughout my internship, I felt like I was contributing to something meaningful and was delivering a tool that would make an impact on the business. I was challenged, but every step of the project I learned something new. Seeing this project through from start to finish really gave me more confidence in my abilities. The members of the analytics team were actively invested in having me learn new skills and have something to show at the end of it. Being asked to build a simplified tutorial of my work really reinforced what I learned. To read my simplified tutorial, please visit my GitHub.

Looking back, I couldn’t be happier having been accepted to intern with ATD and their AACoE. I was able to learn how tires are manufactured when touring one of their vendor’s tire manufacturing plants and participated in other team building activities like going to the U.S. National Whitewater Rafting Center. The AACoE team is constantly learning from one another and frequent Lunch and Learns offered opportunities for everyone to gain insight from the expertise of others, including what I had cultivated during the internship when I had the opportunity to present. It was only natural that I learned so many technical and non-technical skills in an environment where people constantly communicate about what they’re working on and openly knowledge share. I am so grateful I had the opportunity to be a part of this team.

Deep Learning Coming to the Tire Industry

Forecasting warehouse staffing needs with Long short-term memory (LSTM) recurrent neural networks (RNN)

Advanced Analytics Center of Excellence (AACoE) was invited to speak about an exciting AI-powered tool we built on Deep Learning that improves warehouse staffing and planning.

If you haven’t heard, Deep Learning is the next big thing in the field of Artificial Intelligence (AI). Originally conceived in the early 50’s, Deep Learning is a collection of learning algorithms that imitate human neural networks’ learning mechanism, which allows systems to learn specific tasks extremely well. When given enough training time and data, this powerful capability can perform these tasks better than humans. For example: notice how your Apple photo album (or Android google photos) automatically tags you, your family, your pets and even places you’ve been to in your photos. The underlying AI is running a sequence of what’s called convolutional neural networks (that combines simulated pattern-finding filters and neural networks) to identify consistently occurring objects/animals/humans from your pictures.

ATD Logo, Picasso Style

Here’s a previous blog where we painted the ATD Logo, Picasso Style by using convolutional neural networks to Transfer Painting Styles (PyTorch).

These convolutional neural networks see images so well that it’s beating professional doctors in accurately identifying lung cancer from CT scans. In similar ways, deep reinforcement learning helps Tesla cars drive themselves. It also guides SpaceX rockets by enabling them to land themselves. Recurrent neural networks also make translating different languages easy and convenient through simple Google translate. In many ways, Deep Learning is supercharging the tech industry to accomplish many previously thought impossible AI tasks.

And now Deep Learning is right here at ATD.

As the largest tech-enabled tire distributor in North America, ATD has more than 140 distribution centers in the U.S. and Canada, employing thousands of warehouse associates. With each distribution center located in different geographic locations and servicing a variety of customers, these DC’s require different staffing levels in order to operate efficiently. Each Distribution Excellence Manager (DEM) is responsible to ensure their DC is staffed with the appropriate number of associates in order to get product to our customers.

When looking at how to staff each DC, we asked:

· What are the variables of the staffing levels?

· Are they constant throughout the week?

· Are there different warehouse activities that happen at different times of the day?

· Is there room for efficiency improvement?

Our DEM’s are tasked with managing facility operations, including seeing our deliveries to our customers. For our DC’s to be efficient and safe, they need to be staffed with the right amount of associates. If we’re short staffed, we’re not able to get the product to the customer. But if we’re over staffed, there may be safety issues and increased operational costs. To help resolve this problem and enable our DEM’s with a more efficient way to staff their DC’s, we started to develop a DC staffing tool.

The main purpose of this tool would be:

1. To provide visibility of warehouse activity levels ahead of time so each DEM is able to staff and plan early and scientifically.

2. To recommend detailed resources (hours and headcount) required by time of day, day of the week and day-by-day into the future.

 

To do this, we developed the tool with five main components (shown above). We started analyzing data, mainly historical warehouse activity data, that we gathered from our handheld scanners. We also layered in sales data, vendor delivery data, outbound delivery data and product data. This gave us the core dataset needed for us to see how busy any given DC has been, what tasks occurred and how these tasks were being fulfilled for the past few years, down to the minute.

 

With this rich dataset, we were then able to run forecasting algorithms that could forecast daily activities by task type for each DC. This provided visibility for the DEM’s to see what their DC activity level would be for the next two weeks, day by day. BY having this forecast (accuracy ~85%-94%), a DEM can react to business needs and optimize their staffing needs ahead of time.

Now that we had a good forecast of warehouse activity levels, we needed to think about how this forecast influences the resources needed in the future. We achieved this goal by running an optimization algorithm on top of our daily warehouse activity forecast. The main idea was to study how activities arrived and occurred at each of the DC’s, minute by minute, by constructing a Poisson distribution using historical handheld data. We then used the Poisson distribution to simulate how those forecasted activities happen in the future and calculated what the required resources were to fulfill those tasks and activities.

On the front end, we displayed these two results in a web portal, which is a simple way for the DEM’s to quickly see their DC activities.

We’ve now launched this tool to over 120 DC’s across North America, enabling our DEM’s to staff and plan efficiently for their warehouse operations. We’ve built thousands of Deep Learning models that can generate forecasts and many simulations have been run to generate resource recommendations.

Being able to present this work at the Applied AI Summit has been a rewarding and inspiring experience. ATD is pushing the AI revolution by applying state-of-the-art approaches into real world applications and solving concrete business problems in a traditional industry (that isn’t tech or robotics). This is another step in ATD’s digital transformation and we look forward to sharing more exciting projects and tools with you in the future!
