Projekthistorie

Demand Forecast

Lanxess AG

Konsumgüter und Handel

>10.000 Mitarbeiter

This initiative represents a cutting-edge data science project aimed at crafting a scalable, robust, and highly accurate demand estimation model for better resource and delivery planning. Harnessing the full potential of Azure Cloud's advanced capabilities, the project employs state-of-the-art machine learning algorithms, Sentiment Analysis via LLMs, Model-Explanations via Dash and GenAI-Agents, large-scale data processing pipelines and cloud-based infrastructure to forecast demand across all business units. By optimizing production and logistics, this model drives efficiency and elevate decision-making.

- Creation of an end-to-end workflow tailored to accurately predict demand patterns and behaviors for all business units
- Two-Pronged Approach for Intermittent Demand Forecasting
▪ Binary Prediction: Identifying the occurrence of the next demand instance.
▪ Regression: Estimating the magnitude of the demand.
- Top-Down Forecast pronged together with Bottom-Up-Forecast to increase performance
- Implementation ensemble techniques.
- Use of Azure Synapse for streamlined scalability.
- Leveraging Large Language Models (LLMs) and Azure OpenAI to implement sentiment analysis for customer reports, enhancing qualitative insights.
- Implementation of a GenAI-Agent-System to use data and model logs to explain model outcome
- Deployment of the GenAI-Agent-System as plotly-Dash-App via Docker and Kubernetes
- Deployment of MLFlow-Tracking-Server via Docker and Kubernetes

Cashflow-Forecast

Lanxess AG

Konsumgüter und Handel

>10.000 Mitarbeiter

This initiative represents a state-of-the-art data science project focused on building a scalable, probabilistic, and highly reliable cashflow forecasting system to empower strategic financial planning. Leveraging the advanced capabilities of Azure Cloud, the project integrates Bayesian modeling with Pyro, cloud-native data pipelines, and automated MLOps workflows to generate accurate, uncertainty-aware cashflow projections across all business domains. By combining probabilistic programming, large-scale data processing, and end-to-end Azure infrastructure, the solution delivers transparent, quantifiable forecasts that enable finance teams to anticipate liquidity needs and optimize capital allocation.

Scope of Work:
  1. Creation of an end-to-end workflow tailored to accurately predict cashflow patterns via Pipelines and APIs with FastAPI
  2. Two-Pronged Approach for Receivables and Payables with Pyro
  3. Cashflow-Prediction as combination of Two-Pronged Approach for Receivables and Payables with Pyro
  4. Implementation ensemble techniques to bolster prediction precision.
  5. Evaluate Feature Importance with Shapley Values
  6. Explain Feature Importance with an Agentic AI-Explainer
  7. Use of Azure Synapse for streamlined scalability and accessibility.
  8. Deployment of MLFlow-Tracking-Server via Docker and Kubernetes
