Topics to prepare

Supply Chain Optimization Algorithms
Review fundamental supply chain problems such as vehicle routing, inventory management, and network design. Exercise: Draft a high-level architecture for an AI-driven logistics optimization tool, focusing on how heuristics and machine learning models can be combined to solve complex constraints. This is relevant as 4flow specializes in logistics optimization software.
MLOps and Production Lifecycle
Study the end-to-end lifecycle of AI models, specifically focusing on deployment and continuous monitoring. Exercise: Outline a strategy for monitoring model drift and performance degradation in a production environment. This is critical for the role's requirement to manage AI solutions from prototyping through to production monitoring.

Skills to revise

Generative AI Implementation
