What do you mean the judgment matrix is 9?

The judgment matrix is determined by myself with the scale method of 1-9. I have just finished a systematic project: I have completed the analytic hierarchy process with the cases around me. I calculated it by hand in the afternoon, but I didn't use software. I suggest you borrow a book on systems engineering. I have an ahp courseware, but I'm afraid I can't understand it without a book. Better read it first. . It's easy to understand, but it's just a calculation trouble. . The weighted average method is also very simple. . Just now, I saw many people asking how to find the judgment matrix: I'll type out the rules and post them to you. A scale of 1 means that two elements are equally important. 3 means that the former is slightly more important than the latter. 5 means that the former is obviously more important than the latter. 7 means that the former is more important than the latter. 9 means that the former is much more important than the latter. 2, 4, 6, and 8 represent the reciprocal of the median of the above adjacent judgments. If the ratio of the importance of element I to element J is aij, then the ratio of the importance of element J to element I is aji= 1/aij. For the target tourist destination, you can decide how important the scenery is than the cost. You think that the equal importance is 1: 1, and the strong importance is 9: 1. 6: 1 etc. , every two are compared, and the values are filled in to form a judgment matrix (the judgment matrix is a positive and negative matrix with diagonal product of 1). In fact, your picture is quite clear, but it seems that you don't know the rules. I hope you can understand after reading it. . .
