b.18 seconds

c.3.0 seconds

d.6 seconds

Calls arrive at a call center at an average rate of 100/min. Depending on the availability of a service representative, calls may be either answered immediately or wait in line for the next available representative. On average, including waiting time, a call requires 4.4 minutes. How many callers, on average are in the system at any given time? Assume that there are no dropped calls because of excessive waiting.

a.44

b.440

c.4.4

d.Not enough information

c.Gap between the management's understanding of customer expectation and the service standard

d.Gap between the service standard and service delivered

The bullwhip effect is the

a.Variability in demand observed because of seasonality

b.Turmoil caused in organizations due to rapid changes implemented by managements

c.The variability in the operations competence as one moves upstream in the supply chain

d.The amplification of variability as the demand signal moves upstream in the supply chain

Process drift in six-sigma is related to

a.The tendency for the process mean to shift, over time, from its nominal value

b.The loss of strategic focus after a period of continuous improvement

c.Maintaining the gains made with implemented solutions

d.Problems associated with correctly estimating the variability of a process.

The daily demand for a part is normally distributed with mean of 100 and standard deviation of 10 and no safety stock is maintained. The result is:

a.Stockouts will occur 50% of the time during the lead time.

b.Exactly half of the demand during the lead time will be satisfied.

c.The entire demand during the lead time will be satisfied.

d.There will not be any stockouts during the lead time.
