  • DDI (downstream demand inference) provides an approach to approximate downstream demand for subsequent forecasting. 
  • DDI allows the upstream actor to infer the demand received by the downstream actor without the need for information sharing. This provides a baseline to the upstream actors for further planning. 
  • It has been shown experimentally that DDI generally outperforms a situation where planning is based simply on the actual orders received, and DDI is a much-preferred approach for forecasting demand in a supply chain with disjointed information.
