Now lets calculate the total work load.

For resource one the total workload is a processing time of five

minutes per unit for product A, times five units per hour,

plus five minutes per unit for product B, times 6.25 units per hour,

plus five minutes per unit for product C, times 7.5 units per hour.

Summing this gives us 93.75.

For resource 2,

the total workload is 4 minutes per unit for product a, times 5 units per hour,

plus four minutes per unit for product b, times 6.25 units per hour.

Plus five minutes per unit for product C times 7.5 units per hour.

Summing this gives us 82.5.

For resource three, the total workload is 12 minutes per unit for

product A times five units per hour plus zero for the other values.

This gives us 60.

For resource 4, the total workload is 3 times 6.25 for

product B, plus 3 times 7.5 for product C,

plus 0 for product A, which sums to 41.25 And

finally for resource 5 the total work load is 6 times 5 for product a,

plus 6 times 6.25 for product b, plus 4 times 7.25 for product c.

And this sums to 97.5.

Finally, we can calculate the implied utilization for each resource.

For resource one, 93.75 divided by

120 is 0.78125, or 78%.

For resource two, 82.5 divided by 120 is .6875 or 69%.

For resource three, 60 divided by 60 is simply 1, or 100%.

For resource 4, 41.25 divided by 60 is 0.6875 or 69%.

And for resource 5 97.5 divided by 120 is 0.8125 or 81%.

Then the highest implied utilization is 100% at resource 3.

So resource three is our bottleneck.
