Ferry Transport Simulation

Multithreaded ferry transport simulation using Java (Operating Systems project).

Overview

This project models a ferry system transporting vehicles between two sides of a city. Each vehicle is implemented as a thread, interacting with shared resources such as toll booths, queues, and the ferry.

The system focuses on synchronization, fairness, and efficient resource usage.

Key Features

• Multithreaded design (vehicle threads and ferry thread)
• FIFO vehicle queues (no overtaking)
• Capacity-based ferry loading (maximum 20 units)
• Realistic departure conditions
• Randomized behavior (arrival, delays, starting side)
• Full round-trip simulation for all vehicles

Concurrency Concepts

• Mutual exclusion (toll booths, ferry operations)
• Condition synchronization (boarding and unloading)
• Deadlock avoidance
• Starvation prevention (fair scheduling between sides)

Technologies

• Java
• Multithreading (Locks, Conditions / synchronization)
• IntelliJ IDEA

Output

The simulation logs key events such as:

• Vehicle arrival and queueing
• Ferry loading and departure
• Arrival and unloading

Purpose

This project was developed as part of an Operating Systems course to demonstrate practical application of:

• Thread synchronization
• Resource allocation
• Concurrent system design
