Question 1

A company has recorded the last five days of daily demand on their only product.Those values are 143, 121, 126, 129, and 145.The time from when an order is placed to when it arrives at the company from its vendor is 4 days.Assuming the basic fixed-order quantity inventory model fits this situation and no safety stock is needed,what is the reorder point (ROP)?

Please round to 1decimal place.

Question 2

Using the fixed-time period inventory model, and given an average daily demand of 82 units with standard deviation 5, 7 days between inventory reviews, 2 days for lead time, 102 units in the inventory position, a z-score of 1.96, what is the order quantity?

Please round to a whole number.

Question 3

In the fixed-order quantity model, assuming no safety stock, what is the reorder point (ROP) given an average daily demand of 74 units, a lead time of 4 days, and 798 units on hand?

Question 4

A company wants to determine its reorder point (ROP) when using the fixed-order quantity model. Demand is variable and they want to build a safety stock into ROP. If the average daily demand is 10, the lead time is 3 days, the desired z-value is 1.96, and the standard deviation of usage during a single day is 2, what is the desired value of ROP?

Please round to a whole number.

Question 5

You would like to use the fixed-time period inventory model to compute the desired order quantity for a company. You know that vendor lead time is 5 days and the number of days between reviews is 8. What is the standard deviation of demand over the exposure period, if the standard deviation of daily demand is 10?

Please round to a whole number.
