Summary Introduction
Interpretation:
Impact on frequency of order due to decrease in demand.

Stock keeping unit is the service or product identification code which is a machine-readable bar code. It helps the company to track the product. It will protect the company from stock out. Thus, inventory can be refilled at the current time.

It takes approximately 2 weeks (14 days) for an order of steel bolts to arrive once the order has been placed. The demand for bolts is fairly constant; on the average, the manager, Michelle Wu, has observed that the hardware store sells 500 of these bolts each day.
Because the demand is fairly constant, Michelle believes that she can avoid stockouts completely if she orders the bolts at the correct time. What is the reorder point?
The reorder point is? units (enter your response as a whole number).
As the Manager of Branson’s Department Store, you are responsible for ensuring that reorder quantities for the various items have been correctly established. You decide to test one item and choose product Z. A continuous review inventory policy has been used, so you examine this as well as other records and come up with the following data:
Cost per unit
$35
Holding cost
20 percent of unit cost
Average daily demand
10 units
Ordering cost
$30 per order
Standard deviation of daily demand
3 units
Delivery lead time
4 days
Because customers generally do not wait but go elsewhere, you decide on a service probability of 90 percent. Assume that Branson’s Department Store operates 320 days per year.
[What is the annual demand (D)?
Determine the optimal order quantity, Q*.
Determine the reorder point (R) if demand is constant.
Determine the reorder point (R) if demand is varies.
A store has collected the following information on one of its products:Demand = 4,500 units/year Standard deviation of weekly demand = 12 units Ordering costs = $40/order Holding costs = $3/unit/year Cycle-service level = 90% (z for 90% = 1.28) Lead-time = 2 weeks Number of weeks per year = 52 weeks a.
If a firm uses the continuous review system to control the inventory, what would be the order quantity and reorder point?
