[Total Mark: 100]

N. B.: (1) Question no 1 is compulsory.

(2) Attempt any four questions out of the remaining six questions.

1. (a) Draw the detailed class diagram for the following scenario:- --- (10 Marks)
A product is to be installed to control elevators in a building with m floors. The problem concerns the logic required to move elevators between floors according to the following constraints.
Each elevator has a set of m buttons, one for each floor. These illuminates when pressed & cause the elevator to visit the corresponding floor. The illumination is cancelled when the elevator visit the corresponding floor.
Each floor except the first floor & top floor has two buttons, one to request the up elevator and one to request the down elevator. These buttons illuminate when pressed. The illumination is cancelled when an elevator visits the floor & then moves in the desired direction.
