The Advanced Life Support (ALS) project uses Equivalent Mass (EM) to report ALS progress and in technology selection. Life Cycle Cost (LCC) is much more widely used. We develop a new metric, Life Cycle Mass (LCM), from EM and a mass-based LCC model. EM, LCM and Mass (M) alone are compared for technology ranking and progress reporting. These metrics are usually highly correlated and typically produce similar technology rankings and ALS progress metrics. Since M is much simpler than EM or LCM, ALS analysis could use M (Mass) alone for initial technology ranking and for ALS metric reporting.
