# Mass, cost and performance tradeoff
# Scope: Two supplied alternatives, minimizing cost and mass; pairwise dominance only.
# Status: illustrative worked example; engineering review pending.
# Inputs are example values. Checks are editable example requirements, not standards.

costA = 10
massA = 2 kg
costB = 12
massB = 1.5 kg

costDifference := costA-costB
massDifference := massA-massB [kg]
tradeoff := costDifference*massDifference [kg]

check opposing objectives example: tradeoff < 0 kg

scenario alternative: costA = 8
