What it does
A forecast, the right safety stock and a restock plan for each product. Give it sales history and supplier lead times and you get what to order, how much buffer to hold, and when. It picks the forecast method by how each item behaves: moving averages for steady items, smoothing for noisy ones, seasonal splits for items with seasons, and regression when price or promotion drives sales. Accuracy is checked with weighted error, bias and a tracking signal that warns when a model drifts. Safety stock uses your service level, demand swings and lead time. It also estimates the effect of promotions and flags seasonal ramps and slow-moving items.
