R49 / Mc:Mc-1

Bank Level call has chosen for service zero, one or many Accessible Shaft Level

Accessible Shaft Level will service call from zero, one or many Bank Level

---

When a passenger requests a Cabin going up or down at a Floor for some Bank any Shaft in that Bank can potentially service the request. The Bank Level must apply some algorithm to choose the appropriate Cabin. Factors such as Cabin speed, location, direction and current workload can be taken into account. The choice is made immediately after the up/down request and registered as a Floor Service in the requested direction.

Formalization

Floor Service.(Bank, Floor) -> Bank Level.(Bank, Floor)
Floor Service.(Floor, Shaft) -> Accessible Shaft Level.(Floor, Shaft)

Constraints

The Bank Level and Accessible Shaft Level are at the same Floor so these have been merged into one referential Floor attribute in Floor Service.
