How to Set an MDEA Reorder Point for Your Plant

Your warehouse has enough N-methyldiethanolamine (MDEA, CAS 105-59-9) for several weeks of routine makeup. The next order, however, needs time for preparation, transport and receiving approval. A reorder point connects that replenishment time with expected consumption so purchasing can act before stock reaches the reserve level.

Estimate consumption during replenishment

A basic reorder point combines expected demand during replenishment lead time with safety stock. Use consumption records for the grade your plant actually buys, then account for known changes in production or operating plans. learning.sap.com

Reorder point = expected consumption during lead time + safety stock

Keep the quantity basis consistent. If stock is recorded as kilograms of delivered solution, express consumption and incoming orders on that same basis.

Include the time needed to release material for use

For purchasing planning, measure the time from order release until the shipment is available to the plant. Include the expected preparation, transport, clearance, inland delivery and receiving review time that applies to your supply route.

In a hypothetical example, a plant expects to use 200 kg per day, has a replenishment lead time of 35 days and holds 2,000 kg of safety stock.

Reorder point = 200 × 35 + 2,000 = 9,000 kg

This gives the planner a 9,000 kg trigger for reviewing the next replenishment order.

Check open orders before releasing another purchase

When the trigger is reached, review usable stock, confirmed incoming quantities, their arrival dates and any outstanding requirements. Material awaiting quality release needs its own status in the planning record. Confirm that incoming deliveries will arrive before the demand they are intended to cover.

Plan a scheduled solvent replacement separately when it creates a one-time requirement above routine makeup consumption.
