What this part means

The lower label selects a particular version, component, or indexed member of the quantity. For example, x₀ and xₜ can be values at different positions.

Its job in the formula

A subscript distinguishes a version, component, step, or member of a quantity. It does not automatically mean multiplication.

The passage around this formula

The useful ordering is by expected loss. For a mode m with arrival rate λm\lambda_m , mean time to detection τm\tau_m , and cost per undetected instance ℓm\ell_m , the loss accrued before anyone intervenes is approximately
