Answer:
a. The process flow time is 1.50 hours
b. The average flow time of parts that go through inspector B is 1.433 hours
c. The average flow time of parts that will pass the inspection=1.5 hours
d. To have a better flow time performance the ideal thing would be to have more quantity produced
Explanation:
a. In order to calculate the process flow time we would have to calculate the following formula:
process flow time=percentage of parts which will later be sent to inspector A*(tunning flow time+1)+percentage of parts which will later be sent to inspector B*(tunning flow time+B flow time)
process flow time=40%*(0.6+1) + 60%*(0.6+0.833)
process flow time= 1.50 hours
The process flow time is 1.50 hours
b. In order to calculate the average flow time of parts that go through inspector B we would have to calculate the following formula:
average flow time of parts that go through inspector B=flow time tunning+flow time B
average flow time of parts that go through inspector B=0.60+0.833
average flow time of parts that go through inspector B= 1.433 hours
c. In order to calculate the average flow time of parts that will pass the inspection we would have to calculate the following formula:
average flow time of parts that will pass the inspection=number will pass of A*(tunning flow time+1)+number will pass of B*(tunning flow time+ flow time B)
average flow time of parts that will pass the inspection=(14/35)*(0.6+1) + (21/35)*(0.6+0.833)
average flow time of parts that will pass the inspection=1.5 hours
d. To have a better flow time performance the ideal thing would be to have more quantity produced
