A key aspect of dispatching is avoiding conflicts in yard slot or dock door usage, i.e. appointment setting.
In TNX, every site can have a list of yard slots or dock doors, along with rules such as what they can be used for, how fine grained they can be scheduled, and their particular working hours. Carriers who accept a tender can then select from the available appointment slots, and revise them later if allowed and available. The result is a centralise scheduling process that is still self-serve for all the carrier community. And very easy to use.
One important differentiator is that a site can be shared among many organisations, such as a port, rail hub, or airport ULD drop point.
