Answer 1

Utilization can be calculated using the formula utilization = average output rate / maximum capacity.

Utilization = number of lots x setup time + processing time x number of units / number of hours per day x working days per year  

Utilization = [200 x 1 + (45/60) x 2000] / (8 x 215)  = 1700 / 1720 

Utilization = 0.9884   

The utilization is 0.9884 or 98.84%. capacity cushion can be calculated by subtracting the utilization from 1. The capacity cushion is 0.01163 or 1.17%
