Abstract: An asset management platform (AMP) processes messages from mobile assets to enable data-driven monitoring and management of the assets. The mobile assets transmit messages to the AMP specifying the assets' current locations and other information. Modules in the AMP normalize and augment the messages using state information and other data stored in a database. A router routes copies of the messages to multiple destinations, including applications and a business operations middleware (BOM) module. The BOM includes queues for holding messages of different types and subscribers for processing the messages in the queues. An event-action subscriber processes messages as specified by event-action rules. The event-action rules provide flexible and extensible asset tracking, fleet management, and notification capabilities.
