The work that the carrier seeks to find when returning to the point where he has started his main working route is called the return load.
The most important problem in the process of finding the return load is the loss of time of the carrier. Every hour that the return load cannot be found means a decrease in capacity utilisation and efficiency for the carrier.
The return to the departure point is essential because the departure point is where the carrier has started the carriage in order to carry out his main business. In some cases, the return load represents the carrier's return to his home and family. The return load constitutes one of the main factors affecting the carrier's profit/loss. While an advantageous return load maximises profit, the impact on the opportunity cost of a late return load or a commercially unfavourable return load can be significant.
