What role does tier rank play in subnetworks?

Tier rank plays a crucial role in determining the trace order of a subnetwork from different tiers. Each tier in a utility network holds a specific rank, which influences the sequence in which elements are processed during tracing operations. When performing a trace, the system prioritizes certain tiers over others based on their ranks; this means that higher-ranked tiers will be considered first in the tracing calculations.

This hierarchical organization allows for efficient management of the network, ensuring that traces respect the logical flow and hierarchy established by the tier system. By controlling the order in which subnetworks are evaluated, tier ranks help optimize network analysis tasks, such as tracing connectivity or analyzing impacts on the network, which is essential for decision-making in utility management.

Other choices, while they touch on related concepts within network management, do not accurately capture the primary function of tier rank in relation to subnetworks.
