“…1 with linguistic variable in L, use a HA as: HA = {X, H, {c + , c − }, {0, W , 1}, ≤ }, in which X="size of flow", c + = high, c − = low, W ="med", H="very", vl = "very low". Using domain converting method in [13][14][15], the LG is constructed as in Fig. 2 (some edges don't draw to keep clearing figure).…”
