If you travel to first and second-tier cities of China, you will find on the street many delivery drivers (Chinese: 快递).

They take the parcels from small warehouses called customer service centres (Chinese:客户服务中心) located in each neighbourhood and deliver them to the final customers.

These centres are key elements of the Logistics Network of the major courier companies in China. …

With the recent surge in shipping price due to container shortage, the price of a container from Shanghai to North Europe went from $2,000 in November to a peak of $12,000, optimizing your container loading became a priority.

Scenario
You are Logistics Manager in an International Fashion Apparel Retailer and you want to ship 200 containers from Yangshan Port (Shanghai, PRC) to Le Havre Port (Le Havre, France).

  • Retail value (USD): your goods’ retail value is 225,000$…

How many articles have you read stating that “Excel is Dead, long live Python”, “Python is the new Excel” or “Excel became obsolete”?

But when you look around you, in your team or other departments you can hardly find other colleagues using Python.

And when you mention it, it is seen as a black box that people can’t trust because “it’s too complicated”, “we can’t see formulas” or “I cannot run it on my computer”.

Increase Warehouse Productivity by using Reinforcement Learning for Automated Guided Vehicles Routing

Example of AGV setup with 8 workstations — (Image by Author)

In a Distribution Center (DC), walking from one location to another during the picking route can account for 60% to 70% of the operator’s working time. Reducing this walking time is the most effective way to increase overall productivity.

In a previous series of articles, I have shared several methods using optimization strategies to reduce the walking distance of operators in your warehouse. (Link)

These methods have limits when you have a large picking area. Therefore, automated solutions, using Automated Guided Vehicles (AGV) that brings the shelves directly to the operators, are now very popular.

Supply chain optimization makes the best use of data analytics to find an optimal combination of factories and distribution centres to match supply and demand.

Because of the current surge in shipping costs, companies start to challenge their current footprint to adapt to the post-covid “New Normal”.

In this article, we will present a simple methodology using Linear Programming for Supply Chain Optimization considering

  • Fixed production costs of your facilities ($/Month)
  • Variable production costs per unit produced

The Power of Visualization

The frustrated genius

You are a proud Data Scientist presenting your new solution designed using optimized code, fancy libraries, advanced linear algebra and complex statistical concepts.

And […]

Your solution got less interest, recognition or enthusiasm from your management than a simple PowerBI dashboard presented by a new intern the day before.

Have you faced this frustration?

You need to develop your skills in visualization

Simple fancy visualization can have more impact than a very complex model, especially for a non-technical audience.
