# Predictive Kanban & Pull Systems
Kanban is the heartbeat of lean manufacturing — it signals when to produce and how much, ensuring work flows based on actual consumption rather than forecasts. But traditional kanban has a weakness: it is designed for stable, repetitive production. AI makes kanban work in environments with demand variability, mixed models, and uncertain lead times.
Traditional kanban formula: K = (D × L × S) / C Where D = demand rate, L = lead time, S = safety factor, C = container quantity.
The problem: D, L, and S are treated as constants, but they fluctuate. AI recalculates continuously:
