It really depends on whether the capacity is fixed or not. If capacity is fixed and demand is unlimited (eg. because you just can't get more EUV light sources this year) then you should probably run as close to 100% utilisation as possible.
But if you can easily scale production capacity, you should not strive for 100% utilisation. You should expand capacity before you reach 100%, because if you are running at 100% you will not be able to take any more orders and lose the opportunity to grow your business.
