Lean Leader Summit


Dr. Katharina Egert

Supply Chain Data Science Project Manager

Katharina Egert has studied Mathematics, Computer Science and Philosophy at Darmstadt, Germany and Lund, Sweden. After completing her master’s degree, she has obtained a PhD in mathematics which included a six-months research stay at The University of Tokyo and Waseda University, Tokyo, Japan.

She worked both as a data analyst and data scientist in Paris, France focusing on applications in supply chains. She is interested in end-to-end solutions for strategic inventory management decisions such as purchasing, dispatching or inventory-risk pricing. As a consultant, she worked for clients in retail such as fashion eCommerce platforms as well as industry. For her, a key ingredient to meaningful supply chain decisions is the embracing of risks: Usually, it is not the average demand situation, but the extreme cases that poses challenges to any supply chain.

Her team ranked 6th out of 909 competing teams in the Kaggle M5 forecasting competition predicting Walmart sales.

Currently, she is a project manager at DB Fernverkehr AG: Their supply chain management is in charge of managing stock of train repair parts across its national warehousing network.


Intelligent inventory management for a complex spare parts supply chain

Lean Leader Summit 2024

DB Fernverkehr AG’s supply chain is currently driven by a classical time-series forecast and reorder point planning procedures. This approach proves to be insufficient to manage new parts for new train series as well as complex repair life cycles of bigger components.

In her talk, Katharina highlights the most exciting steps in her journey to apply her AI toolkit to enable DB Fernverkehr to reach their economic availability targets for stocks in line with their “Strong Rail” initiative.
