Restaurant Management System with Java Threads and Semaphores

Introduction

This project aims to simulate the daily operations of a restaurant using multithreading concepts in Java. The system manages customer groups, waiters, chefs, and a cashier, each handled as separate threads. The goal is to implement thread synchronization and resource management in a real-time environment.

Project Overview

The restaurant management system consists of the following components:

1. Processes:

   • Customers entering the restaurant
   • Waiters taking orders
   • Chefs preparing orders
   • Customers making payments

2. Threads:

   • Each customer is represented as a separate thread upon entering the restaurant.
   • Each waiter works in a separate thread to serve customers.
   • Each chef works in a separate thread to manage the cooking process.
   • Cashier operations, payment collection, and table clearing are handled in a separate thread.

3. Synchronization:

   • Synchronization is required among customer threads for table selection and seating order.
   • Waiter threads coordinate order taking and serve their assigned customers.
   • Chefs coordinate with limited cooking resources to avoid conflicts.
   • The cashier thread handles payment processing for one order at a time.

Technologies Used

• Java threads
• Semaphores for synchronization
• Multi-threading concepts for parallel processing

Usage

1. Installation:

   • Clone the repository:

     git clone https://github.com/your/repository.git
     

   • Navigate to the project directory:

     cd project-directory
     

   • Install any necessary dependencies.

2. Running the Application:

   • Start the application using your preferred Java IDE or command line tools.

3. Accessing the Interface:

   • The application should provide a user-friendly graphical interface to interact with the restaurant simulation.

Important Notes

• All actions performed by the system should be logged in real-time to a text file.
• Presentation of static values (such as time intervals and quantities) may be subject to dynamic updates during runtime.
