Software Engineering

Notes (b) Develop a list of behavioral rules that would be incorporated in the formulation of
the model of the elevator system (e.g., when does an elevator change its direction of
motion, which of the elevators responds to a particular call for service, where does
an idle elevator ‘park,’ etc.?)
(c) A model’s behaviour can ‘unfold’ only as a consequence of input data. Develop a list
of input data requirements that would necessarily become an integral part of a
study of the elevator system, for example, arrival rates of tenants at each of the
floors, velocity of the elevators, and so on.
4. What are the types of systems?
