The flowchart consists of multiple steps, represented by rectangular and diamond-shaped boxes connected by arrows, flowing mostly from left to right and then looping back. The process begins with an oval labeled “Start.” It leads to a process box labeled “Fuzzy Number Transformation into Vector Format,” which shows the transformation of fuzzy numbers into vector form. It contains a matrix with factors F 1, F 2, and F 3, leading to a fuzzy number scale. From top to bottom, the scale shows the labels V L, L, V H, L, and V H. This scale leads to a numeric vector matrix. The entries in the matrix are as follows: Row 1: 0, 0.25, 0.5. Row 2: 0.25, 0.5, 0.75. Row 3: 0.25, 0.5, 0.75. Row 4: 0.75, 1, 1. Row 5: 0.25, 0.5, 0.75. Row 6: 0.75, 1, 1. Next, a rectangular box labeled “Calculate the correlation of each respondent with the average of other respondents” is illustrated with four circles in a large circle containing colored icons of respondents. Each circle has two parts: the left part contains three respondents, and the right part contains one. A decision diamond labeled “If smaller collation less than 0.3” follows. It contains a similar split visual showing three respondents on the left and one respondent on the right. If yes, the flow moves upward to a rectangular box labeled “Remove the respondent with the lowest collation,” indicated by a single respondent icon, which is further connected to the box “Calculate the correlation of each respondent with the average of other respondents.” If no, the flow moves downward. The downward arrow leads to a rectangular box labeled “Generate all possible split half,” showing respondents divided into two groups within three circles inside a large circle. Each circle has two parts: the left and right parts contain two respondents. Next, a rectangular box labeled “Compute the correlation value of each split-half” leads to another box labeled “Compute the average adjusted split-half correlations.” The flow then loops back from the last step to the “Start” oval, indicating iteration or completion of the process.The detailed of consistency rate calculation.
