A dynamic ECO is defined for zone ZN03. There are 8 tasks starting from ZN03, 4 of which are subscribed to resources.

Nina Chunyo, a forklift driver, selects the system-guided option using her presentation device. Her highest priority task involves moving a handling unit from ZN03. Nina has the capacity for simultaneously moving 4 handling units from ZN03. The 4 tasks available in ZN03 are subscribed to Nina in what is called soft allocation. Nina is sent to ZN03 and, since the task involves a dynamic ECO, Nina can choose any handling unit in the zone and will be assigned its corresponding task (semi system-guided mode).

A few seconds later, Seamus O’Hara, another forklift driver, selects a system-guided task. His highest priority task also involves moving a handling unit from ZN03. But since all of the available tasks in ZN03 are subscribed to resources, the ECO is unavailable for Seamus, and he receives a different task involving another zone.

In the case of semi system-guided tasks, the tasks are not assigned to resources (as is the case with user mode and system-guided mode). The soft allocation prevents resource bottlenecks, ensuring the workability of semi system-guided mode. In the above case, if there was no dynamic ECO, it would be possible that both Nina and Seamus would both travel to ZN03 at the same time, looking to execute tasks.
