HELP PLEASE!! CORRECT SOLUTION PLEASE;
You manage the shipping of item #A452 from your supplier. The shipments for this item are delivered to the nearest port, and you have to transport them to the distribution center. You have two options, truck load (TL) and less than truck load (LTL).
Your company needs 5000 units of #A452 per year and it is purchased at a price of $39 per unit. Each order costs $95. Your company uses a holding charge of 0.14, a cycle service level of 90% and 365 days per year for planning purposes.
The truck load (TL) option costs $1500 per load. It takes 4 days to deliver and each truck can carry up to 1200 items.
The less than truck (LTL) load option costs $2.2 per item. It takes 6 days to deliver.
You have three options,
OPTION A: to use the TL option and delivery full truck loads,
OPTION B: to use the TL option and delivery the economic order quantity
OPTION C: to use LTL option and deliver the economic order quantity.
For all following parts, consider transportation costs as an item cost unless otherwise specified. i.e., the total variable cost of #A452 in the Full truckload is $1500/1200items + $39/item = $40.25/item.
(Option A) Full truckload
What is the sum of average pipeline and cycle inventory, ordering, and purchase costs for option A? Please provide your answers rounded to the closest dollar.
(Option B) Truckload with EOQ
What is the economic order quantity? Use the item cost without the transportation for this calculation. Please answer in whole numbers.
If you order the EOQ calculated earlier, what is the sum of average pipeline and cycle inventory, ordering, and purchase costs for option B? Consider transportation costs as an item cost, and use the EOQ in whole numbers for calculation. Please provide your answers rounded to the closest dollar.
(Option C) Less than truckload
What is the sum of average pipeline and cycle inventory, ordering, and purchase costs for option C? Consider transportation costs as an item cost, and use the EOQ in whole numbers for calculation. Please provide your answers rounded to the closest dollar.
Explanation / Answer
Given that,
Annual demand, D = 5000 units
Order cost, S = $ 95
Holding charge, h = 0.14
Daily demand rate, d = 5000/365 = 13.7
(Option A) Full Truckload (TL)
Truckload quantity, Q = 1200 units
Lead time, L = 4 days
Holding cost, H = 39*0.14 = $ 5.46
Pipeline inventory = d*L = 13.7*4 = 55
Cycle inventory = Q/2 = 1200/2 = 600
Unit cost, C = 39+1500/1200 = $ 40.25
Sum of average pipeline and cycle inventory, ordering, and purchase costs = (55+600)*5.46 + (5000/1200)*95 + 5000*40.25 = $ 205,222
(Option B) Truckload with EOQ
EOQ = SQRT(2DS/H) = SQRT(2*5000*95/5.46) = 417
Cycle inventory = Q/2 = 417/2 = 209
Unit cost, C = 39 + 1500/417 = $ 42.6
Sum of average pipeline and cycle inventory, ordering, and purchase costs = (55+209)*5.46 + (5000/417)*95 + 5000*42.6 = $ 215,580
(Option C) Less Than Truckload (LTL)
Lead time, L = 6 days
Pipeline inventory = d*6 = 13.7*6 = 82
Cycle inventory = Q/2 = 417/2 = 209
Unit cost, C = 39 + 2.2 = $ 41.2
Sum of average pipeline and cycle inventory, ordering, and purchase costs = (82+209)*5.46 + (5000/417)*95 + 5000*41.2 = $ 208,728
Option A (Full Truckload) is the most economical one.
