sectorbranch
Sectorbranch is a term used to describe a branching structure that connects a central sector to multiple sub-sectors in hierarchical models. The concept combines ideas from sector classification and branching in graphs to capture how larger domains subdivide into more specialized units. It is used across several disciplines to model organization, responsibility, or data flow within a system.
In formal terms, sectorbranch refers to a rooted branching relation where each sub-sector is contained within
Applications include economic sector classifications, supply-chain models, and modular software architectures. For example, a sector representing
Variants emphasize dynamics: sectorbranches can be created, merged, or reconfigured as conditions evolve, such as policy
