What is a system that triggers ordering on a uniform time basis called?

The term that describes a system which triggers ordering on a uniform time basis is referred to as a fixed-period system. In this type of system, inventory levels are reviewed at predetermined intervals, and orders are placed accordingly, regardless of the actual inventory level at the time of review. This approach allows for consistent timing in order placement, making it easier to manage order schedules and predict supply needs. The main advantage is that it can simplify the ordering process and make it easier to coordinate inventory needs with suppliers.

Other systems, such as continuous review systems, monitor inventory levels continuously and may require orders to be placed at any time when stock drops below a certain threshold. In contrast, a periodic review system typically refers to an inventory management approach that also uses fixed time intervals for reviewing stock, but with a focus on adjusting orders based on the current inventory during that review period, rather than strictly adhering to a time-based ordering trigger.

The clarity between these terms is crucial, especially when considering different inventory management strategies and their applications within supply chains.
