2. What is the effect on the amount of safety stock provided by the stochastic continuous-review model presented in Sec. 19.5 when the following change is made in the inventory system. (Con- sider each change independently.) (a) The lead time is reduced to 0 (instantaneous delivery). (b) The service level (measure 1) is decreased. (c) The unit shortage cost is doubled. (d) The mean of the probability distribution of demand during the lead time is increased (with no other change to the distribu- tion). (e) The probability distribution of demand during the lead time is a uniform distribution from a to b, but now (ba) has been doubled. (f) The probability distribution of demand during the lead time is a normal distribution with mean μ and standard deviation σ, but now σ has been doubled.
Jawab:
(a) If the lead time is reduced to 0, the amount of safety stock would be reduced because there is no longer a need to account for the time it takes to receive a new shipment.
(b) If the service level (measure 1) is decreased, the amount of safety stock would be increased because a lower service level means a higher risk of stockouts, and therefore, a greater need for safety stock.
(c) If the unit shortage cost is doubled, the amount of safety stock would be increased because a higher cost of stockouts means that there is a greater need to avoid them, and therefore, a greater need for safety stock.
(d) If the mean of the probability distribution of demand during the lead time is increased, the amount of safety stock would be increased because a higher mean demand means a higher likelihood of stockouts, and therefore, a greater need for safety stock.
(e) If (ba) is doubled, the amount of safety stock would be increased because a wider range of possible demand means a higher risk of stockouts, and therefore, a greater need for safety stock.
(f) If σ is doubled, the amount of safety stock would be increased because a larger standard deviation means a higher risk of stockouts, and therefore, a greater need for safety stock.

5. a letter is selected at random from each of the word 'NICE' and 'ICE' represent the sample space using a possibility diagram and find the probability two letters are the same and the vowels!
Jawaban:
Correct options are A) , B) and C)
(A) Total number of letters in the given word = 4, out of these O and E are two vowels.
Let S be the sample space, then
S={HO,HM,HE,OM,OE,ME}⇒n(S)=6
Let A1 be the event of taking two vowels, then
A1={OE}=n(S)n(A1)=61
(B) Let A2 be the event of taking at least one vowel, then we have
A2={HO,HE,OE,ME,MO}⇒n(A2)=5
Hence, required probability =n(S)(n(A2))=65
(C) Let A3 be the event of taking one letter as M, then we have A3={HM,OM,ME}⇒n(A2)=5
Hence,required probability =n(S)n(A3)=63=21

9. John is playing a chess game against Peter. If the probability that John will win is 4/7 and the probability that Peter will win is 1/7 , find the probability that the chess game will end in a draw.
John probability + Peter probability
= 4/7 + 1/7 = 5/7
Draw probability
= 7/7 - 5/7 = 2/7
So the probability that the chess will end in a draw is 2/7

19. The number of houses sold by an estate agent follows a Poisson distribution with a mean of 2 per week. Find the probability that in the next 4 weeks, the estate agent sells more than 6 houses.
Jawab:
An average of 2 per week means that the agent on average sells 8 houses per month (per 4 weeks). Therefore, we are going to compare the probability of the agent selling more than 6 houses per month given the average of 8 per month (λ = 8).
P(x = k) = λ^k × e^(-λ) ÷ k!
P(x = 0) = 8^0 × e^(-8) ÷ 0!
P(x = 1) = 8^1 × e^(-8) ÷ 1!
P(x > 6) = 1 - P(x ≤ 6)
P(x > 6) = 1 - [P(x = 0) + P(x = 1) + P(x = 2) + P(x = 3) + P(x = 4) + P(x = 5) + P(x = 6)]
P(x > 6) = 1 - P(x <= 6)
P(x > 6) = 1 - 0.31337
P(x > 6) = 0.68663
