Abstract

In an airport baggage handling system bag information, flight information and airport topology information are provided to a central processor which determines a path for the bag through the handling system. The bag is scanned at various points along the path and the scan time is compared with a predetermined arrival time for the bag at the scan point. A bag is marked at risk if it arrives at a scan point after the predetermined time and the system may suggest an alternative handling path for the bag if it is determined that the risk of the bag not making an outbound flight is too high.

acquiring information about the identity of the items, the arrival and departure parameters for the item and the topology of the location through which the item may pass between arrival and departure;

for each item, defining a path though the handling system from a plurality of valid paths and storing details of that path, the path including a plurality of checkpoints at which the item is identified and recorded;

at each checkpoint, determining a status of each item based on the time of arrival of each item at the checkpoint compared to a target time of arrival, the items each being assigned one of a plurality of statuses including an indication of whether the item is at risk of not arriving at the departure point by a required time;

where an item is assigned an at risk status, determining an alternative path through the system, and communicating the alternative path to a controller.

a store for storing item identity data provided from the item processor, arrival and departure parameters provided from the rules engine, and location topology information including the plurality of paths;

a user application for communicating data relating to arrival and departure parameters and items to a system user; and

a plurality of checkpoints arranged along the paths, each checkpoint including a scanner for scanning items to provide item identity and time of arrival information to the rules engine to determine a status of each item based on the time of arrival of each item at the checkpoint compared to a target time of arrival, the items each being assigned one of a plurality of statuses by the rules engine including an indication of whether the item is at risk of not arriving at the departure point by a required time;

wherein when an item is assigned an at risk status, the rules engine determines an alternative path through the system, and communicates the alternative path to the user.

17. A system according to claim 16, comprising a status agent communicating with the store and the rules engine for receiving item identity information updates and arrival and departure parameter updates from the rules engine and communicating those updates to the store.

18. A system according to claim 16, wherein the items comprise baggage.

19. A system according to claim 18, wherein the location is an airport and the arrival point is the arrival of an item of baggage on an incoming flight and the departure point is the departure of the item of baggage on an outbound flight, wherein each item of baggage has a unique identifier, and wherein the scanner at each checkpoint scans the items of baggage to retrieve the unique identifier at one of a plurality of scan locations and communicate the identity to the rules engine together with the time of the scan, and the rules engine compares the time at which the item is scanned to a time at which the item is expected to be scanned at that scanning location.
