Which triggering method allows for immediate adjustments in the MRP/DRP system?

The triggering method that allows for immediate adjustments in the MRP (Material Requirements Planning) / DRP (Distribution Requirements Planning) system is the Continuous Net Change method. This approach enables real-time updates to inventory, demand, and supply data as changes occur, which is crucial for maintaining an accurate and responsive planning system.

With Continuous Net Change, the system continuously monitors variable factors such as inventory levels, lead times, and order statuses. As soon as a change is detected, the system recalculates requirements and suggests the necessary adjustments. This immediacy can lead to better inventory management, reduced out-of-stock situations, and a more responsive supply chain.

In contrast, methods such as Net Change (Night Run) and Regenerative tend to operate on a scheduled basis, meaning they process changes only at set times (like end-of-day or periodically). These methods may result in delays or gaps in data accuracy, as they do not react to changes in real-time. Static Update typically involves manual intervention to refresh data and does not reflect instantaneous changes, making it less effective for dynamic environments where agility is essential. Therefore, Continuous Net Change stands out for its ability to facilitate immediate adjustments based on the latest data inputs.
