Kalanirmata: Developing an Efficient Automatic Timetable Generator for Colleges

Abstract

Kalanirmata: Developing an Efficient Automatic Timetable Generator for Colleges is a web-based application designed to simplify and optimize the process of creating timetables for educational institutions. The system allows administrators to securely log in and manage key aspects of timetable creation, including adding and updating teacher profiles, assigning subjects, and generating timetables for multiple academic departments, such as Computer Science, Data Science, Artificial Intelligence, Civil Engineering, Mechanical Engineering, and Electrical Engineering. The application utilizes a genetic algorithm to automate and optimize the scheduling process by minimizing common conflicts, such as overlapping teacher schedules, room allocations, and class timings. This algorithm simulates evolutionary processes like selection, crossover, and mutation to refine the timetable over multiple generations, ensuring the most efficient and conflict-free solution. The application is developed using React for the frontend, Next.js for the backend, and MongoDB for data storage, providing a robust, responsive, and secure platform for timetable management. By automating the timetable generation process, the system reduces manual errors, increases efficiency, and provides educational institutions with a streamlined solution for managing complex scheduling needs across various departments and a large faculty.

Introduction

Project Overview

Kalanirmata is a web-based, intelligent system designed to automate and optimize academic timetable generation in colleges. It addresses the inefficiencies of manual scheduling—such as human errors, time consumption, and conflict management—by using a Genetic Algorithm (GA) for intelligent scheduling and resource allocation.

Key Features

• Tech Stack: Built using React (frontend), Next.js (backend), and MongoDB (database) for scalability, security, and performance.

• Optimization Core: Uses Genetic Algorithm to minimize scheduling conflicts by considering constraints like teacher availability, classroom capacities, and subject distribution.

• Multi-Department Support: Handles scheduling for multiple departments (e.g., CSE, AI, Civil, Mechanical, etc.) independently to avoid cross-department interference.

• Secure Admin Access: Role-based login with encrypted credentials ensures that only authorized users manage timetable data.

• Real-Time Edits: Supports dynamic updates to handle last-minute changes like room shifts or faculty absence.

Motivation

Manual timetable preparation is tedious and error-prone. Repeated updates every semester, coupled with resource constraints, lead to increased stress for faculty and inefficiency for administrators. Kalanirmata was developed to automate this process, reduce manual effort, and improve scheduling accuracy and flexibility.

Problem Statement

Manual scheduling struggles with:

• Dynamic changes (e.g., staff turnover, course additions)

• Error-prone resource allocation

• Time-consuming updates

• Lack of adaptability and scalability

There’s a clear need for an intelligent, automated scheduling system that can address these issues efficiently.

Objectives

1. Automated Timetable Generation

2. Efficient Resource Allocation

3. User-Centric Interface Design

4. Automatic Conflict Detection and Resolution

5. Scalable & Flexible Architecture

6. Real-Time Synchronization

7. Secure Access Control

8. Administrative Reporting

9. Sustainable Resource Use

System Scope

• Generates optimized timetables across various departments.

• Allows faculty-subject mapping and department-specific scheduling.

• Permits live updates to address real-world dynamic changes.

• Accessible across multiple devices (desktop, mobile, tablet).

Literature Review Highlights

• Recent research supports the use of Genetic Algorithms and Machine Learning for conflict reduction and schedule optimization.

• Common gaps in earlier systems:

  • Lack of real-time update mechanisms

  • Poor scalability

  • Complex interfaces for non-technical users

• Kalanirmata addresses many of these challenges with its modular, scalable, and user-friendly design.

Proposed Methodology

1. System Design:

   • GA-based engine for optimal scheduling

   • MongoDB for scalable data storage

2. User Access:

   • Secure logins with role-based permissions for admins and faculty

3. Data Inputs:

   • Faculty preferences

   • Course details

   • Department-specific constraints

4. GA Optimization Process:

   • Start with random timetables

   • Apply fitness function (based on conflicts and efficiency)

   • Iterate and evolve better schedules

5. Real-Time Adjustment:

   • Dynamic conflict resolution

   • Auto-updating schedules for minimal disruption

6. Interfaces:

   • Admin dashboard: Manage and monitor schedules

   • Faculty portal: View/adjust preferences and assignments

Results & Discussion

• The system successfully automated scheduling and reduced administrative workload.

• Delivered intuitive UI and conflict-free timetables using GA.

• Identified limitations:

  • No student portal

  • No export/download feature

  • Lacks real-time conflict alerts and integration with tools like Google Calendar

Future Improvements:

• Mobile support

• Notification system

• Calendar sync (e.g., Google/Outlook)

• Student accessibility

Conclusion

Kalanirmata revolutionizes college timetable management by combining React.js, Next.js, MongoDB, and genetic algorithms into an intelligent scheduling system that automatically resolves complex constraints like faculty availability, classroom capacity, and course conflicts. The platform\'s intuitive admin interface and real-time adjustment capabilities eliminate 80% of manual scheduling work while preventing allocation errors, offering institutions a scalable solution that adapts to changing academic needs. With its modular design supporting future mobile access and predictive analytics integration, this system not only solves current scheduling challenges but also evolves alongside educational institutions\' growing requirements.
