Teachers Automatic Time-Table Software Generation System using PHP

This project involves creating a PHP-based system for automatically generating time-tables for teachers. The system will automate the scheduling process, considering constraints such as teacher availability, classroom capacity, and subject requirements.

System Overview

The Teachers Automatic Time-Table Generation System includes the following features:

• Teacher and Subject Management: Manage teacher profiles and subjects, including teaching hours and preferences.
• Classroom Management: Define classrooms with capacities and availability.
• Scheduling Algorithm: Automatically generate time-tables based on constraints and preferences.
• Conflict Resolution: Identify and resolve scheduling conflicts.
• Time-Table Display: Provide a user-friendly interface for viewing and managing the generated time-table.

Implementation Guide

Follow these steps to develop the automatic time-table generation system:

1. Design the Database Schema

   Create tables to manage teachers, subjects, classrooms, and time-tables. Example schema:

   
                           -- Teachers table
                           CREATE TABLE teachers (
                               id INT AUTO_INCREMENT PRIMARY KEY,
                               name VARCHAR(255),
                               available_hours VARCHAR(255),
                               preferred_subjects TEXT
                           );
   
                           -- Subjects table
                           CREATE TABLE subjects (
                               id INT AUTO_INCREMENT PRIMARY KEY,
                               name VARCHAR(255),
                               hours_per_week INT
                           );
   
                           -- Classrooms table
                           CREATE TABLE classrooms (
                               id INT AUTO_INCREMENT PRIMARY KEY,
                               name VARCHAR(255),
                               capacity INT
                           );
   
                           -- Time-tables table
                           CREATE TABLE time_tables (
                               id INT AUTO_INCREMENT PRIMARY KEY,
                               teacher_id INT,
                               subject_id INT,
                               classroom_id INT,
                               day ENUM('Monday', 'Tuesday', 'Wednesday', 'Thursday', 'Friday'),
                               time_slot ENUM('Morning', 'Afternoon', 'Evening'),
                               FOREIGN KEY (teacher_id) REFERENCES teachers(id),
                               FOREIGN KEY (subject_id) REFERENCES subjects(id),
                               FOREIGN KEY (classroom_id) REFERENCES classrooms(id)
                           );
                       

2. Develop the Scheduling Algorithm

   Implement an algorithm to generate time-tables based on constraints. Consider using optimization techniques such as constraint satisfaction or linear programming.

   
                           // Example pseudo-code for scheduling
                           function generateTimeTable($teachers, $subjects, $classrooms) {
                               foreach ($subjects as $subject) {
                                   foreach ($teachers as $teacher) {
                                       if (canTeach($teacher, $subject) && hasAvailableClassroom($classrooms)) {
                                           $timeTable[] = assignTimeSlot($teacher, $subject, $classroom);
                                       }
                                   }
                               }
                               return $timeTable;
                           }
                       

3. Build the User Interface

   Create PHP scripts or use a framework to manage CRUD operations for teachers, subjects, and classrooms. Provide an interface for generating and displaying the time-table.

   
                           
                           <form action="generate_time_table.php" method="post">
                               <button type="submit">Generate Time-Table</button>
                           </form>
                       

4. Conflict Resolution

   Implement logic to identify and resolve scheduling conflicts. Ensure that no teacher or classroom is double-booked and that all constraints are met.

5. Testing and Deployment

   Thoroughly test the system to ensure that time-tables are generated correctly and meet all constraints. Deploy the application to a web server and ensure it is secure and functional.
