Plazza - Pizzeria Simulation

Overview

The Plazza is a project that simulates the operations of a pizzeria, including a reception, multiple kitchens, cooks, and pizza cooking processes. The simulation focuses on aspects like load balancing, process/thread synchronization, and inter-process communication (IPC).

Key Features

• Interactive Shell: Allows users to place pizza orders and view the status of kitchens, including current cook occupancy and ingredient stocks.

• Dynamic Kitchen Creation: Kitchens are created as child processes as needed, depending on the incoming order volume. Each kitchen contains a predefined number of cooks (threads), and can only accept a limited number of pizza orders at a time.

• Load Balancing: Orders are allocated pizza by pizza to the kitchens in a balanced manner to avoid kitchen saturation.

• Communication: Uses inter-process communication (IPC) to facilitate communication between the reception and the kitchens.

• Logging: Maintains a record of completed orders, which are also displayed to the user.

• Ingredient Stock Management: Each kitchen starts with a stock of ingredients, which regenerate every N seconds.

Technical Details
