A method and apparatus that automatically tracks, monitors and schedules
the shipping of objects through carriers such as delivery trucks, ships,
or planes is disclosed. A tracking tag is attached to each shipped
object. The tracking tag and transportation system uses such techniques
as GPS, cellular technology, and bar coding, and sensors such as those
that make temperature, pressure, and noise measurements as sources of
tracking information. Logic rules and hierarchical weights are given to
each source, for any given condition so that the most accurate tracking
is made. Tracking is continuous throughout the object's trip. Another set
of logic rules is applied to take actions to intervene in the shipping
process. For example if it seems the object is off schedule, upgrades or
downgrades to the shipping are made. The transportation system can be
integrated within a customer's company to facilitate easy scheduling, and
production management. A user-friendly graphical user interface is
available which displays item, time and distance related information.
