Finding Analysis objects
- For every <<external input/output device>> object, there is a corresponding software device interface object.
- Each elevator has a state-dependent control object called Elevator Control, which control the elevator motor and door.
- Because requests or the elevator can come at any time, a decision is made to have a separate coordinator object, called the Elevator Manager, to receive all incoming requests for the elevator and to update the elevator plan.
- An entity object is needed for each elevator, which we call Elevator Status & Plan.
