The graph, titled “Linguistic Terms for Fuzzy-DEMATEL and Fuzzy-TOPSIS Models,” illustrates the varying effects of different linguistic terms used in these models. The horizontal axis is labeled “X subscript i,” ranging from 0 to 1 with an interval of 0.1. The vertical axis is labeled “mu of (X subscript i),” ranging from 0 to 1 with an interval of 0.1. There are five colored curves in the graph, each representing a different linguistic term. The blue curve represents “No Effect slash Very Poor,” starting from (0, 0), rises vertically to (0, 1), and then decreases linearly to (0.25, 0). The orange curve represents “Very Little Effect slash Weak,” starting from (0, 0), rises linearly to (0.25, 1), and then decreases linearly to (0.5, 0). The green curve represents “Low Effect slash Moderate,” starting from (0.25, 0), rises linearly to (0.5, 1), and then decreases linearly to (0.75, 0). The red curve signifies “High Effect slash Good,” starting from (0.5, 0), rises linearly to (0.75, 1), and then decreases linearly to (1, 0). Lastly, the purple curve represents “Very High Effect slash Very Good,” starting from (0.75, 0), rises linearly to (1, 1), and then decreases vertically to (1, 0).
