Figure 1.
A flowchart lists 10 steps for deriving cause-and-effect relationships from expert matrices, with an acceptability check and a feedback loop.The flowchart begins with Step 1: define sample and subsamples. Step 2 gathers expert opinion as matrices A subscript k. Step 3 calculates average matrix A. Step 4 calculates the normalized initial direct-relation matrix B. Step 5 derives the total relation matrix T. Step 6 calculates the sums of rows R subscript i and columns C subscript j of matrix T. Step 7 sets the threshold value alpha. Step 8 builds the cause-and-effect relationship diagram. Step 9 asks whether the diagram is acceptable. If the answer is no, the flow returns to Step 7. If the answer is yes, the flow continues to Step 10, which derives final cause-and-effect relationships.
