From the previous section we know that unused
length in this lot is 0' .
We also know that the unused width in this lot is 6'
Unused Width per Parking Stall = Unused Width / # of Driving Aisles = 6'/ 2 = 3'
Additional Stall Required = SWidth - Unused Stall = 8' - 6' = 2'
Additional Stall per Parking Stall = Additional Stall Required / # of Driving Aisles
= 2' / 2 = 1'
Therefore, one can not change the aisle width or entrance width without changing the optimal solution.
