CASE 10-1: MINNETONKA WAREHOUSE

Question 1: For each of the four work team sizes, calculate the expected number of trucks in the queue waiting to be unloaded.

Size of teamNumber of trucks in queue
23.2
3 .5
4 .27
5 .12

Question 2: For each of the four work team sizes, calculate the expected time in the queue—that is, the expected time a truck has to wait in line to be unloaded.

Size of teamExpected time in queue
2.8 hours
3.125 hours
4.067 hours
5.030 hours

Question 3: For each of the four work team sizes, what is the probability that a truck cannot be unloaded immediately?

Size of teamProbability that truck must
wait upon arrival
280%
350%
440%
530%

Question 4: Which of the four work teams has the lowest cost to Wayne?

Size of teamTotal cost
2\$268.00
3\$102.00
4\$96.00
5\$95.32

Question 5: Wayne is also considering rental of a forklift to use in truck unloading. A team of only two would be needed, but the hourly cost would be \$38 per hour (\$28 for the workers and \$10 for the forklift). They could unload a truck in five minutes. Should Wayne rent the forklift?

From the printouts, we must determine how much “idle time” there is with the present system. This depends in part upon the crew size. For a crew of four, for example, 24 minutes per...
