This problem deals with stochastic demands in multiple periods. Here is the demand information:

Day	1	2	3	4	5	6	7	8	9
Demand	2	2	5	4	1	3	3	2	1

The initial inventory is 6. The lead time is 3 days. We will receive what we ordered at the end of the day.

If we are using (s, Q) policy with s=2 and Q=5. Which of the following statement is not true?

	A.	The net inventory on day 3 is -3.
	B.	The order quantity on day 6 is 0.
	C.	The order quantity on day 5 is 0.
	D.	The inventory position on day 9 is 3.

Continue on Q6, if we change the policy to (s, S) with s=3 and S=6. Which of the following statement is not true?

	A.	The order quantity on day 9 is 3.
	B.	The inventory position on day 3 is 1.
	C.	The order quantity on day 5 is 4.
	D.	The net inventory on day 7 is -5.

Continue on to Q6, if we change the policy to (R, S) with R=4 and S=10. Which of the following statement is not true?

	A.	The order quantity on day 4 is 10.
	B.	The inventory position on day 5 is 9.
	C.	The net inventory on day 7 is -14.
	D.	The order quantity on day 9 is 0.

Finally, if we change the policy to (R, s, S) with R=3, s=2, and S=6. Which of the following statement is not true?

	A.	The net inventory on day 7 is -5.
	B.	The order quantity on day 6 is 0.
	C.	The order quantity on day 9 is 6.
