Perpetual inventory control In a perpetual inventory system, stock levels are monitored continuously and action is triggered as the stock approaches which level?
-
AMaximum level
-
BMinimum level (reorder point trigger)
-
CAverage level
-
DEconomic order quantity
-
ESafety stock always, regardless of level
Answer
Correct Answer: Minimum level (reorder point trigger)
Explanation
Introduction / Context:Perpetual inventory control maintains up-to-date records of receipts, issues, and balances, enabling timely replenishment decisions and reducing stockouts or overstocking.
Given Data / Assumptions:
- Transactions are recorded continuously (bin cards or computerized systems).
- Reorder point is based on lead time demand plus safety stock.
- Action levels (max, min, reorder) are defined.
Concept / Approach:Perpetual systems compare the on-hand balance to the reorder point (a form of minimum level). When balance falls to or below this trigger, a purchase order is initiated so that replenishment arrives by the time stock would otherwise run out.
Step-by-Step Solution:Compute reorder point = average demand during lead time + safety stock.Track perpetual balance after each issue/receipt.When balance ≤ reorder point (minimum action level), place an order for EOQ or planned lot size.
Verification / Alternative check:Historical records should show reduced stockouts and balanced carrying costs after implementing reorder point control.
Why Other Options Are Wrong:Maximum and average levels are reference bounds, not the primary trigger; EOQ is an order size, not a stock level; ordering at safety stock regardless of level is inefficient.
Common Pitfalls:Failing to account for lead time variability; inaccurate transaction posting leading to phantom stock or shortages.
Final Answer:Minimum level (reorder point trigger)
