The most amazing application of mathematical optimization in logistics

What is SCOT?

The state of the art in advanced mathematics at the service of the operations management. I like how some important companies implement this scientific development. — Julio Mora Olivares

SCOT is an acronym meaning Supply Chain Optimization Technologies. Probably it is the largest and the most complete application of operational research in the field of logistic.

In summer 2017, I discovered that Amazon was hiring operational researchers in Italy. This intrigued me enough to start some research on the Internet. I found a plentiful source of information on LinkedIn profiles, where people were sharing their working experience, their goals and successes.

I’ve collected all the pieces of information and, with my experience, I was able to reconstruct a whole picture of this project.

Human resources

First things first: people

The team working on SCOT project covers many countries. In my search, I’ve noted places from North America, India, and Europe. This is a quite common characteristic of projects developed in large companies as Amazon.

What really impressed me indeed is to see so many roles involved in the same project. They are:

  • Econometricians,
  • Statisticians,
  • Economists,
  • Operational Research Scientists,
  • Machine Learning Scientists,
  • Software Engineers,
  • Product Managers

So, from the management point of view, the project leader has to handle two independents source of complexity: many roles in many places.

Applications

Fantastic combination of Optimization, Computer Languages. and Inventory Management — Deepak Bammi

Have you ever bought something from Amazon? A book, of course. But also other goods as a Kindle reader or a cover for your smartphone.

I did all of this and every time, before the purchase order, I knew a precise forecast of the delivery date. Typically one day for many Prime products.

A so elevated level of service quality can be achieved with a full control of the supply chain. From my research seems that Amazon invested a lot on:

  • inventory planning and control;
  • last mile logistic network.

Inventory planning and control

Inventory planning involves many algorithms to buy inventory in the right quantities, at the right frequencies, from the right vendors, and assigning to the best warehouse to fulfill customer demand forecast.

The picture above was taken from an Amazon video on YouTube. Probably it gives only a vague idea of the inventory complexity managed behind the button “buy now with 1-click (r)”.

If you want some totals here they are:

Hundreds of millions of items, for hundreds of product lines worth billions of dollars of inventory world-wide.

In a single sentence, the team of inventory planning control of Amazon:

decide and optimize what, when, where, and how much should buy to meet Amazon’s business goals and to make their customers happy.

Last mile logistic network

Another important area where SCOT gives a major improvement is the last mile logistics.

If you think of the entire user experience, the parcel delivery is the only ring of the supply chain out of the control of Amazon. But everybody knows how Amazon is obsessed with customer experience and satisfaction.

This means not only the optimal location of the delivery point to get an appropriate geographic coverage. But also control a complete fleet of people and vehicles physically delivering goods.

Technologies and IT impacts

From the technology point of view, SCOT has many interesting things to say.

Optimization library

SCOT is an optimization library designed and built with the purpose to facilitate the integration, of optimization models, within the Amazon’s infrastructure without any knowledge of optimization.

General purpose optimization engines

SCOT uses well known and powerful optimization engine: CPLEX, XPRESS and GUROBI.

Programming languages

SCOT has some kind of relationship with the following programming languages:

  • ruby
  • VB
  • c#
  • java
  • python (my favorite)

I don’t know what is the main language used for SCOT. Also, I didn’t find any relationship with compiled languages such as C or C++.

SCOT in a video

If you want, you can enjoy this short video from Amazon explaining what is SCOT.

An example of logistics at Amazon

Have you ever bought something at Amazon? Most probably, the answer is yes. What’s before the delivery? To have an indirect answer to this question, I’ve verified what kind of information is available on an order as a regular customer.

Among the tools to check the journey of the parcel, one of these provides full tracking of the delivery. So, I tried to see what the steps for an order with six days delivery were.

The online order was submitted on the 23rd of November 2022, and the item arrived on the 29th of November 2022. Take a look at the map below. The parcel crossed four different delivery stations: two in France and two in Italy.

Any single step of the delivery was properly scheduled with a decision support system built with an operational research tool.
