What is the difference between INTER and INTRA pruning strategies?
INTRA pruning strategy applies optimization constraints (Budget, Coverage, Plan IRR targets) individually to every service area selected, i.e. every service area aims to achieve same budget or coverage targets.
INTER pruning strategy applies optimization constraints to the whole plan. For example, 80% coverage target input aims to achieve 80% coverage across all areas and locations selected into optimization, with coverage achieved in individual service areas varying based on where best investment returns are possible.
Segment IRR-based optimizations evaluate attractiveness of individual network nodes and are thereby not bound by service area-level constraints (i.e. the setting is irrelevant).
For plans involving just a single service area this setting is irrelevant, and both options imply same logic to be applied to the optimization.
