A client pipeline processes almost 7 million invoice records across 28 months for ~459 locations and 6,000+ products, uses dtw clust hierarchical clustering (shape and dynamic time warp distances) to reduce 459 stores to seven clusters, applies decomposition with statsmodels to separate trend, seasonality and residuals, and fits a sigmoid recovery fit to anomalies (e.g., Hurricane Harvey) to measure recovery length and slope for forecasting and operational planning.
