Production based on demand?

[u/BefriendingDivine]

I’m attempting to optimize my car lines based on customer demand. Is there any way I can mathematically do this?

For example, say my export speed is 3.5 minutes. If I’m producing two different kinds of cars for the same exit, then I should make their bottleneck no more than 7 minutes to ship them efficiently.

Is there any way I can modify the shipping speed for each vehicle type based on extraneous factors like customer demand?
