a. Container selection mode
1) "Load in the order containers are entered in the list" — the optimization goal is to load by the specified container (vehicle, package) order and quantities.
Example: a batch must first fill two 40GP containers, then load the remainder into a 20GP.
On the Container interface, first add 40GP, then 20GP; set the 40GP quantity to 2.

On the Loading rules interface, set Container selection mode to "Load in the order containers are entered in the list". The result will fill two 40GP first and load the rest into the 20GP.

2) "Automatically choose a container combination using the fewest containers" — minimize the number of containers used.
3) "Choose a container combination by minimum total cost" — minimize total container cost.
To use this rule, you must fill in the container fee on the Container interface.

4) "Choose the container with the highest volume utilization" — pick the container with the highest load ratio.
