Designing an Elevator System

An elevator system is a system that controls the movement of elevators in a building. The elevator system is a complex system that consists of multiple components such as elevators, floors, buttons, and displays.

Code

This repository contains the design and implementation of an elevator system.

Elevator System

The Notes folder contains algorithms, class diagrams, use case explanation and requirements.

Components

The implementation has the following components:

• ElevatorSystem: The main class that manages the elevators and their interactions.
• ElevatorCar: Represents individual elevators, including their state and behavior.
• Floor: Represents the floors in the building, including the display and hall panels.
• Button: Abstract class for buttons, with specific implementations for elevator and hall buttons.
• Display: Manages the display of the current floor and direction of the elevator.
• EmergencyHandler: Handles emergency situations, such as fire alarms and power outages.
• MaintenanceHandler: Handles maintenance requests, such as setting an elevator to maintenance mode.

Algorithm

• SCAN algorithm: Moves the elevator in two direction, servicing requests along the way.

Test

The Test folder contains the test cases for the elevator system. You can also run specific tests using:

python -m pytest elevator_system/tests/test_algorithm.py

C Interoperability

The project includes a C interoperability layer located in elevator_system/interop.c.
