This is perhaps "minimum", considering equations 1.5-7 seem to be "translations" of equations 1.2-4 in terms of characteristic functions instead of sets. So $\bigvee \mu_{A_i} = 1$ means the union of the sets is the whole set (equation 1.1). Although I'm not quite sure equations 1.3 and 1.5 are correct: it seems $= \varnothing$ and $=0$ are missing. – 2012-06-28
