If demand for an inventory item is normally distributed with a mean of 150 units per day and standard deviation of 2 units/day,

lead time is normally distributed with an average of 4 days and standard deviation of 0.5, and service level is 95% (z=1.65) , at what point should it be reordered?

Answer:

ROP (xy) = 724 units to be recorded

Step-by-step explanation:

Given:-

- Demand for an inventory item(x) is normally distributed with :

                       mean ux = 150 units/day

                       standard deviation sx = 2 units/day

- lead time(y) is normally distributed with:

                       mean uy = 4 days

                       standard deviation sy = 0.5 days

- Service level is 95% (zs=1.65):

Find:-

at what point should it be reordered?

Solution:-

- We will deonte (xy) the number of units to be serviced to be normally distributed with mean and standard deviation:

                       uxy = ux*uy = 150*4 = 600 units

                       sxy = √[(uy*sx^2) + ux^2*sy^2 ]

                              =√[(4*2^2) + 150^2*0.5^2 ]

                              = 75.10659

- At the service level of 95% the confidence interval would be:

                       ROP (xy) = uxy + zs*sxy )

                       ROP (xy) = 600 + 1.65*75.10659

                       ROP (xy) = 724 units to be recorded

A. 2, 200, 2000  

This is multiplying the number by 10 each time. In other words, just adding an extra zero to the end of it. 

b. 340, 0.034 

This one is moving the decimal place forward two places. 10^-2, so removing two zeros from the end of it until eventually you reach decimals and have to move the decimal forward twice, which is essentially what you're doing here.

c. 85700, 857, 0.857

In this one, you remove one zero from the end. You move the decimal forward once when you reach the decimals. This would be 10^-1

d. 444000, 4440000, 44400000

In this one, you multiply each one by 10. Add on a zero to each one.

e. 0.095, 9500000, 950000000

You multiply this one by 10^2, so the number increases.
