Transport Management System: Zones
are associated with service providers. They may be applied to all services (the carrier default) or just one service. They are used in various places
in the system as a standard hierarchy of destinations. It becomes a very
powerful mechanism for rating data as well as analysing it.
Rating by zone
Initially, the ratings system
will take the destination entered in the transaction and attempt to
find a rate covering that specific zone. If a match is not found, the system
then attempts to
place the destination within a zone hierarchy for either the
current service or the carrier default.
Example Zone Hierarchy:
Example: Postcode 2020
(Mascot, NSW) has been entered into the transaction. Not finding a rate, the
software will search for a containing postcode range for the current service. Not finding a
postcode range, it will then try and find a containing postcode range in the
default zone hierarchy for the carrier. If it is found within a postcode
range then the program will take the parent local zone and attempt to find a
rate associated with that. Not found by the local zone it continues to move
up the hierarchy trying successive levels until a match is found. This
processing can start at any point so that the user may have entered "SYD
SYDNEY" as a local zone into the transaction.
