Complete question:
Videoworld is a discount store that sells color televisions. The monthly demand for color television sets is 100. The cost per order from the manufacturer is $600. The carrying cost is $64 per set each year. Assume a year has 360 working days. Determine the following values rounding to the nearest integer (answer them using only numbers without any sign such as the dollar sign, comma, ...):
Q1. The optimal quantity per order: Q2. The minimum total annual inventory costs:
Q3. The optimal number of orders per year:
Q4. The optimal time between orders (in working days):
If the store had an inventory policy that allows shortages with the shortage cost per set estimated at $80, determine the following values:
5) The optimal quantity per order when the store allows shortages
6) The optimal storage level when the store allows shortages
7) The optimal number of orders when the store allows shortages
8)The optimal time between orders (in working days) when the store allows shortages.
Answer:
1) 150
2) $4,800
3) 8
4) 45 days
5) 201
6) 89
7) 6
8) 60 days
Explanation:
We are given:
Monthly demand, = 100
Cost per order, S= $600
Carrying cost, H = $64 per set/ year
Shortage cost, Cs = $80
Yearly demand will be, D= 100*12 =1200
1) The optimal quantity per order:
2) The minimum total annual inventory cost:
Average inventory * H
Where average inventory = Q*/2
Therefore,
Average inventory * H
= 75 * 64
= $4,800
3)The optimal number of orders per year:
4) The optimal time between orders:
5)The optimal quantity per order when the store allows shortages:
= 201.25 ≈ 201
6) The optimal shortage level when the store allows shortages:
= 89.33 ≈ 89
The optimal shortage level when the store allows shortages = 89
7) The optimal number of orders per year when the store allows shortages:
No. of orders =
= 5.97 ≈ 6
Optimal number of orders per year = 6
8) The optimal time between orders (in working days) when the store allows shortages:
Time between orders = Number of working days/ Number of orders
The optimal time between orders (in working days) = 60 Days
