If we need to decide whether to use a zone or not and if yes then which zoning approach to use it all depends on the waiting time requirements and speed of the elevators. 3) It then assigns the lift which is going up and nearer to that floor. So, this algorithm works as an elevator and hence also known as the elevator algorithm. If there are no further requests in that direction, then stop and become idle, or change direction if there are requests in the opposite direction. Join the community of over 1 million geeks who are mastering new skills in programming . Abstract and Figures. Then there is a bank. First there is an elevator class.
