Why Fancy Destination Dispatch Elevators Often Perform Worse Than Simple Buttons

Why Fancy Destination Dispatch Elevators Often Perform Worse Than Simple Buttons

I explore the hidden complexity behind elevator algorithms, comparing basic SCAN and LOOK systems with advanced Otis RSR logic. While smarter re-optimization usually reduces wait times, I discovered that rigid Destination Dispatch kiosks often perform worse than traditional buttons because they lack flexibility. The data reveals that keeping things simple frequently beats over-engineering in everyday building traffic.

The kiosk enforces rigidity, you must get in the assigned elevator, and the loss in flexibility is not worth the extra information for the optimizer.
