Parker Hi$-$Fi Systems

Parker Hi$-$Fi Systems, located in Wellesley, Massachusetts, a Boston suburb, assembles and sells the very finest home theater systems. The systems are assembled with components from the best manufacturers worldwide. Although most of the components are procured from wholesalers on the East Coast, some critical items, such as LCD screens, come directly from their manufacturer. For instance, the LCD screens are shipped via air from Foxy, Ltd$.,$ in Taiwan, to Boston's Logan airport, and the top$-$of$-$the$-$line speakers are purchased from the world$-$renowned U$.$S$.$ manufacturer Bos's.

Parker's purchasing agent, Raktim Pal, submits an order release for LCD screens once every $4$ weeks. The company's annual requirements total $500$ units $(2$ per w'orking day$),$ and Parker's per unit cost is $$1,500.($Because of Parker's relatively low volume and the quality focus $-$ rather than volume focus $-$ of many of Parker's suppliers, Parker is seldom able to obtain quantity discounts.$)$ Because Foxy promises delivery within $1$ week following receipt of an order release, Parker has nev$$r had a shortage of LCDs$.($Total time between date of the release and date of receipt is $1$ week or $5$ working days.$)$

Parker's activity$-$based costing system has generated the following inventory$-$related costs. Procurement costs, which amount to $$500$ per order, include the actual labor costs involved in ordering, customs inspection, arranging for airport pickup, delivery to the plant, maintaining inventory records, and arranging for the bank to issue a check. Parker's holding costs take into account storage, damage, insurance, taxes, and so forth on a square$-$foot basis. These costs equal $$150$ per LCD per year.

With added emphasis being placed on efficiencies in the supply chain, Parker's president has asked Raktim to seriously evaluate the purchase of the LCDs$.$ One area to be closely scrutinized for possible cost savings is inventory procurement.

Discussion Questions

What is the optimal order number of LCDs that should be placed in each order?

What is the optimal reorder point $($ROP$)$ for LCDs$?$

What cost savings will Parker realize if it implements an order plan based on EOQ?

Please provide solutions for discussion questions, thanks!
