Which Data Structure U Will Prefer to Design a Lift System?

When designing a lift system, it is essential to choose the right data structure to efficiently manage the movement of lifts and ensure smooth operations. Different data structures have their own advantages and disadvantages, so it is crucial to evaluate which one would be most suitable for the specific requirements of the lift system.

Let’s explore some common data structures and their potential application in lift system design.

1. Array

Using an array to represent the floors of a building can be a straightforward approach. Each element in the array can store information about the current status of a particular floor, such as whether it needs to be visited by a lift or not.

However, this simplistic representation has limitations when dealing with complex lift systems that require efficient algorithms for floor scheduling.

2. Linked List

A linked list can be used to represent each floor as a node, with pointers connecting them together. This allows for dynamic allocation and deallocation of floors as needed.

However, searching for a specific floor or optimizing lift movement may become challenging due to the linear nature of linked lists.

3. Queue

A queue data structure can be employed to manage requests from different floors in an organized manner. Each request can be enqueued at one end and dequeued from another end when serviced by a lift.

This ensures fairness in handling requests but doesn’t necessarily optimize lift movements.

4. Binary Search Tree (BST)

A BST is well-suited for maintaining an ordered list of floors based on their priority or distance from the current position of lifts. This enables efficient searching and insertion operations, making it useful in scenarios where quick decision-making is required to optimize lift movements.

5. Graph

A graph data structure can be employed to represent the building’s floors as vertices and the connections between floors as edges. This allows for modeling complex relationships between different floors, such as direct connections or weighted edges representing distances.

Graph algorithms like Dijkstra’s algorithm can then be utilized to find the shortest path for lift movement.


In conclusion, the choice of data structure for designing a lift system depends on several factors, including the complexity of the system, required optimization algorithms, and desired functionality. While arrays and linked lists offer simplicity, queues ensure fairness in handling requests.

BSTs provide efficient searching and insertion operations, whereas graphs enable modeling complex relationships between floors. Therefore, it is crucial to carefully analyze the specific requirements and constraints of the lift system before making a decision about which data structure to use.
