In which triggering method does the MRP/DRP system run only at scheduled times during the night?

The Net Change (Night Run) method is designed to execute the Material Requirements Planning (MRP) or Distribution Requirements Planning (DRP) processes at designated intervals, typically during non-operational hours such as overnight. This approach allows the system to evaluate demand and supply changes that have occurred since the last run, thus ensuring inventory levels are adjusted appropriately without disrupting daily operations.

This method is particularly advantageous for organizations that prefer to minimize operational downtimes and optimize the planning process when the least amount of activity is occurring, which often coincides with nighttime. By scheduling it in this way, the MRP/DRP system can compile and process large datasets effectively without impacting the performance of the system during business hours.

In contrast, other methods like Continues Net Change (Immediate) operate in real-time, addressing updates as they happen; Regenerative methods perform a complete recalculation based on the entire dataset each time they are run, which can be resource-intensive; and On Demand methods are triggered by specific user actions, making them less predictable. All these alternatives do not specifically emphasize a nightly processing schedule, making the Net Change (Night Run) method distinctive and suitable for environments where overnight processing is feasible and beneficial.
