16. Refer to datact 7, what is the optimal order quantity? A) IRI B) IRS C 196 D) 200 E) 250 ? 17, which of the following is not correct about the bullwhip effect a results in order increasing fluctuations at each step of the upstream supply chain in chain by increases the costs associated with inventory the supply results in decreasing variations in demand quantities d, occurs because of distortions in information in the supply chain C. All of the above are correct about the bullwhip effect 38. Which the following of smoothing constants would make an exponential smoothing forecast cquivalent to a naive forecast? a 0.0 b. 0.6667 C. 0.5 d, 1.0 e, 0.3333 39. In the basic EOC model, if the inventory holding cost per item per year triples, and all other values remain constant, the EOQ will a decrease by about 42% b. decrease by exactly 73% c. increase by about 73% d, increase by about 58% e, decrease by about 58% 40. A service level of 95% means a there is a 0.95 probability of a shortage in inventory b. there is a 0.95 probability of a stockout C. there is a 0.05 probability that supply will exceed demand d, there is a 0.05 probability that demand will be met during the lead time e. None of the above 1. Which of the following qualitative forecasting method uses three types of participants: decision makers, staff personnel, and respondents? a executive opinions b. sales force composites c. weighted moving average method d, time series analysis method e. None of the above

Explanation / Answer

36. a (181)

Q=Root{ 2dk/h}

H= 35$

D= 400 *12 = 4800

K= 120$

Q= Root{ (2*120*4800)/35)=181.42

38. d. (1.0)

y^T+1|T = yT+(1)yT1+(1)2yT2+,

where 01 is the smoothing parameter

when =1, y^T+1|T=yT   and forecasts are equal to the naive forecasts.

39. a. (decreases by about 42%)

{Root (1/3)-1}/1 = -.42 *100 = -42% (decreases by 42%)

40. e. (none of the above)

A service level of 95 percent means that there is a 0.95 probability that demand will be met during the lead time, and the probability that a stockout will occur is 5 percent or .05
