# Fleet Management for Logistics and Transportation

## Scenario
ABC Logistics is a medium-sized logistics company that operates a fleet of trucks to transport goods across the country. To optimize their operations and enhance efficiency, they decide to implement a comprehensive Fleet Management System (FMS) application.
The FMS application provides real-time GPS tracking for each vehicle in the fleet. Dispatchers and managers can monitor the location, speed, and route of each truck on a live map, allowing for efficient route planning and better coordination.
The application integrates with fuel sensors to monitor fuel levels and consumption patterns in real-time. It analyzes fuel usage and provides insights into fuel efficiency, enabling the company to reduce fuel costs and implement eco-friendly practices.
The FMS application maintains a record of each vehicle's maintenance history and schedules regular maintenance based on mileage, usage, or time intervals. Automated alerts are sent to maintenance teams and managers for timely servicing, reducing the risk of breakdowns and ensuring vehicle safety.
The application integrates with the company's inventory management system to track goods and cargo being transported. It provides visibility into the status of each shipment, ensuring accurate delivery timelines and enhancing customer satisfaction.
The FMS application generates detailed weekly reports and analytics on various aspects of fleet operations. These reports help management in making informed decisions, optimizing resource allocation, and identifying areas for further improvement and cost-saving measures.
