Answer :
Answer:
1. Reorder point = 2,290 towels
2. Safety shock = 290 towels
Explanation:
1. Reorder Point
ROP = (Average daily demand * Lead time in days) + Z*б(dlt)
Z= No of SD depending on the service level of 98%
б(dlt) = SD in demand during the lead time
We derive б(dlt) given the SD in demand б(d) = 100 towels/day using the formula
б(dlt) = б(d) *[tex]\sqrt{ Lead time}[/tex] .................(2)
Where the lead time = 2 days
Substitute in equation 2, the value of б(d) = 100 towels/day and Lead time = 2 days to obtain
б(dlt) = 100 * [tex]\sqrt{2}[/tex]
б(dlt) = 100 * 1.4142
б(dlt) = 141.42 towels
Substitute in equation (1), Z = 2.05 for a service level of 98%
Average daily demand = 1,000 towels, Lead time = 2 days, б(dlt) = 141.42 towels to obtain
ROP = (1,000 * 2) + 2.05*141.42
ROP = 2,290 towels
b. Safety shock
The safety shock = Z * б(dlt)
Substitute the value of Z = 2.05 and б(dlt) = 141.42 towels to obtain
The safety shock = 2.05 * 141.42
The safety shock = 290 towels
