The vertical axis is labeled “Mu (X)”, and ranges from 0.0 to 1.0 in increments of 0.2 units. The horizontal axis ranges from 0.0 to 1.0 in increments of 0.1 units. Along this axis, the fuzzy linguistic reference points are labeled at the top, from left to right, as “m u”, “M m i”, “m i”, “m v i”, and “m a i”. Five triangular fuzzy membership functions span the graph. The first triangle is the linguistic variable “Very low impact (V L I)”, and is drawn using a dotted line. This triangle begins at point (0.0, 0.0), rises to a peak at the “m u”, where the point is (0.0, 1.0), and then decreases to (0.23, 0.0). The interior of this triangle contains the symbol “V L I”. The second triangle is “Medium to low impact (M L I)”, and is drawn using a densely dotted line. This triangle begins at (0.0, 0.0), reaches its peak at “M m i”, where the point is (0.23, 1.0), and decreases to end at (0.5, 0.0). Inside this triangle is the label “M L I”. The third triangle is “Medium impact (M I)”, and is drawn using a dash dotted line. This triangle begins at (0.23, 0.0), reaches its peak at “m i”, where the point is (0.5, 1.0), and decreases until it ends at (0.73, 0.0). Inside this triangle is the label “M I”. The fourth triangle is “Medium to high impact (M H I)”, and is drawn using a dashed line. This triangle begins at (0.5, 0.0), reaches its peak at “m v i”, where the point is (0.73, 1.0), and decreases until it ends at (1.0, 0.0). Inside this triangle is the label “M H I”. The fifth triangle is “High impact (H I)”, and is drawn using a solid line. This triangle begins at (0.73, 0.0), reaches its peak at “m a i”, where the point is (1.0, 1.0), and falls to end at (1.0, 0.0). Inside this triangle is the label “H I”.
