Me and some colleague's of mine (all of us studied Operations Research) can't figure out which of the following statement is true.

Imagine two call centers
1) a big call center
2) a small call center

Both their targets are (for example) a servicelevel of 70% in 20 seconds, They have to be the same

If both call centers, with respect to the other variables, are completely the same (ie handling time etc)(minus occupancy of course) which of the statements will be true.

The asa of the bigger call center will be lower than the one from the smaller call center
The asa of the bigger call center is equal to the asa from the smaller one.

In real life the difference between the two seems to be there, however we can't prove this, even after trying to use the formula's in Hillier and Lieberman's Introduction to Operations Reasearch we couldn't really figure it out.

Hope one of you can help !!!!
