Presents a methodology for helping the Swedish Ministry of Defence assess the costs and benefits of architectures for network-based operations as the Swedish Defence Forces are reoriented to a wider suite of operations than homeland defence, including operations far from Sweden. 450-character abstract: Presents a methodology to help the Swedish Ministry of Defence assess costs and benefits of architectures for network-based operations as the Swedish Defence Forces are reoriented to a wider suite of missions than homeland defence, including operations far from Sweden. Offers criteria for certain network measures and metrics for those measures, and relates those metrics broadly to interaction categories that support identification of common subnetworks and analogous systems/components in the cost-estimation process.
