First we can calculate our arrival rate.
00:02
We're going to take 1 divided by 1 .1 to get 0 .9091 items per minute.
00:09
Then we can calculate our packing rate.
00:12
Our packing rate is given as tria.
00:16
To calculate this we can find our average which is 3 .35.
00:23
Sorry 3 .35 and then to find our packing rate per minute we'll just do 1 divided by 3 .35 to get 0 .2985 packings per minute.
00:35
Then we want to calculate our total packing rate.
00:38
That is going to be 4 times our 0 .2985 and that is going to give us 1 .194 packings per minute.
00:49
Then we can calculate our service rate for our domestic shoppers.
00:54
We are given again our tria.
00:56
We need to find our mean shipping time.
01:01
When we calculate that we are going to get 2 .133 and then we do 1 over 2 .1333 to get that our 0 .4685 shippings per minute.
01:18
Then to calculate our total service rate for our domestic shoppers we will take 2 times our 0 .4685 and we're going to get 0 .937 shippings per minute.
01:33
Then next we can calculate our utilization.
01:37
Our utilization is going to be our arrival rate divided by our total packing rate and that is going to give us 0 .7615...
