• Model Explainability and Transparency: For stakeholders’ trust and acceptance, it’s essential to develop AI models that are interpretable and provide insights into the rationale behind their predictions.
• Real-time Integration: The AI-powered demand forecasting system needs to be integrated with real-time data feeds on weather conditions, unexpected events, or even passenger activity on social media to continuously refine predictions.

2.2. Predictive Maintenance with AI

• Sensor Integration: Sensors monitoring various aspects of ferry operations, such as engine performance, vibration levels, and fuel consumption, need to be installed and integrated with a centralized data collection system.
• Anomaly Detection with Machine Learning: Machine learning algorithms can be trained on historical sensor data to identify patterns that deviate from normal operating conditions, potentially indicating equipment malfunctions.
• Predictive Maintenance Scheduling: Based on anomaly detection and predicted equipment failure timelines, maintenance schedules can be proactively planned, minimizing downtime and ensuring operational efficiency.

Technical Considerations:

• Sensor Selection and Placement: Selecting the right sensors and strategically placing them on the ferries is crucial for capturing data relevant to equipment health.
• Data Security and Privacy: Measures need to be implemented to ensure the security of sensitive sensor data collected from the ferries.
• Maintenance Expertise: While AI can predict failures, human expertise will remain essential for interpreting the data and performing the actual maintenance tasks.

By addressing these technical considerations, AI-powered demand forecasting and predictive maintenance can significantly enhance the Thessaloniki Waterbus system’s efficiency and reliability.
