The Lift Car Belongs to No Floor

Operational Design Domain Boundaries for an Indoor Delivery Robot in Shared Vertical Circulation

A paper from the School of Continuous Improvement codes 1,412 fallback events from a 61-week deployment of four indoor delivery robots in a nine-storey office building, finding that the lift approach, sill and car produced two-thirds of them in under a tenth of operating time, mostly because a domain specification written floor by floor placed the moving car in no element at all. Respecifying each car as an element of its own nearly eliminated those events over a twelve-week rerun, while fallbacks for crowded cars roughly doubled now that the car carried a capacity condition to exceed.
