GMDH Streamline

GMDH Streamline is a supply chain planning platform that layers demand forecasting, inventory and supply planning, material requirements planning, and sales & operations planning (S&OP) on top of an existing ERP or inventory system. Rather than replacing the system of record, it pulls historical sales, on-hand stock, open orders, lead times, and bills of materials from the connected ERP, generates statistical and AI-based forecasts, and writes back replenishment suggestions, purchase plans, and transfer recommendations. The product is positioned for distributors, manufacturers, and retailers that have outgrown spreadsheet-based planning but find the native forecasting in their ERP too limited.

The forecasting engine automatically analyzes each item for level, trend, seasonality, and intermittency, selecting a model per SKU and validating it against held-out future periods to limit overfitting. Planners can link new products to the history of comparable items, apply seasonal coefficients, layer in promotions and price effects, and override the statistical baseline manually where business knowledge differs from the model. A forecast-approval workflow lets teams mark SKUs as Approved, Unapproved, or Needs Attention and lock approved values, supporting a consensus process across sales, operations, and finance.

On the supply side, Streamline calculates safety stock, reorder points, and min/max levels, and produces optimized order proposals that account for supplier lead times, minimum order quantities, and group economic order quantity (EOQ) across SKUs sharing a supplier or container. It supports multi-echelon distribution networks with inter-site transfers and in-transit tracking, and uses discrete-event simulation at daily resolution to project inventory positions and purchasing signals across the planning horizon. The platform is available as a cloud service and integrates bidirectionally with a published set of ERP, accounting, inventory, and e-commerce systems, plus generic ODBC database and custom API connections.
