a)
To determine: The ordering plan and cost for lot for lot.
Introduction:
Lot for Lot:
The lot for lot method of requirements plan is the process where the planned order release will be equal to the net requirement of the period.
Net requirements plan:
The net requirements plan is the plan which is established on the gross requirements plan formed by deducting the stock on and the
b)
To determine: The ordering plan and cost for EOQ.
Introduction:
Economic order quantity (EOQ):
The economic order quantity is the number of units a firm must add to their stock while making each order. The notion of EOQ is to reduce the total cost of inventory of the firm.
Net requirements plan:
The net requirements plan is the plan which is established on the gross requirements plan formed by deducting the stock on and the scheduled receipts. If the total requirement is below the safety stock levels, a planned order is made based on the given lot sizing technique.
c)
To determine: The ordering plan and cost for POQ.
Introduction:
Periodic order quantity (POQ):
The POQ is the standard quantity of units that will be ordered over a fixed period of time. This method is followed when the usage of raw materials is consistent and is predictable.
Net requirements plan:
The net requirements plan is the plan which is established on the gross requirements plan formed by deducting the stock on and the scheduled receipts. If the total requirement is below the safety stock levels, a planned order is made based on the given lot sizing technique.
d)
To determine: The plan which has the lowest cost.

- Economic order quantity (Q*) is 2,000 units. Annual demand (D) is 12,000 units. Find number of orders per year (N*) and time between orders (T*) in weeks. N*=0.167 times per year, T*= 6 weeks N*=6 times per year, T*= 60.83 weeks N*=6 times per year, T*= 0.167 weeks N*=8.67 times per year, T*= 6 weeks N*=6 times per year, T*= 8.67 weeksarrow_forwardUsing the gross requirements schedule below*, prepare an alternative ordering system that orders every 3 weeks for 3 weeks ahead (a periodic order quantity).

Quantity discounts are available. O d. Lead time does not vary.arrow_forwardA lot-sizing procedure that orders on a predeterminedtime interval with the order quantity equal to the total ofthe interval’s requirement is:a) periodic order quantity.b) part period balancing.c) economic order quantity.d) all of the above.arrow_forwardFind MPS start as wellarrow_forward

Multiples.arrow_forwardThomas' Bike Shop, with a 250 day working year, stocks a high-volume item. The average daily demand is 7p units, the lead time is 4 days, and sometimes may take up to 5 days. a. Calculate the re-order point without safety stock. b. Calculate the re-order point with safety stock.arrow_forwardDennis Sport World, a chain of sporting goods stores, sells 360,000 tennis balls per year. The tennis balls cost Dennis Sport World RM15 per dozen. Annual inventory carrying costs are 20 percent of inventory price. The cost of placing and receiving an order are RM72. Assume the inventory replenishment occurs virtually instantaneously. Based on recent experience, Dennis Sport World uses 7 days delivery time for planning purposes.
