Commonality Scoring Process

Assumes specific Common Core scenarios to assess level of commonality

Index values provided to Costing Tool for each subsystem for a givenCommon Core scenario

Index is fraction of equipment groups common to Core within subsystems(1.0=all equipment types are in core scenario)

Currently modeling 3 scenarios:

Natural Commonality: No equip features forced, common functional needs

Full-Featured: All features forced, all values=1.0, highest mass impact

Build-Your-Own: All features are user-selected

Compares potential Common Core options
