A red judgment is an inverted judgment because the element at the top, Sights, is more important than the element at the left. 4ĥ The judgment in red, 4.0, for Activities at the left versus Sights at the top will be highlighted as the 1 st most inconsistent judgment. Select Inconsistency, 1 st from the menu to reveal the most inconsistent judgment. Return to the pairwise comparison screen by clicking the ABC icon.

It is okay here, but we will show you how to improve it in any case. IMPROVING INCONSISTENCY The Inconsistency ratio, shown at the bottom of the priorities screen is 0.1. If you accidentally end up back on the main screen, click on the tab to return to the Verbal assessment screen and click Calculate. When you finish the comparisons by filling in all the white cells, click on the Calculate icon to find the priorities of the criteria with respect to the goal. Sights are between moderately and strongly more important than Activities Cost is between equally and moderately more important than Activities. So, here we have: Activities are between moderately and strongly more important than nitelife. When it is in black, the one at the left is more important than the one at the right. When the number is in red, it indicates the criterion at the top is more important than the criterion at the left. 3Ĥ Figure 3 shows three of the six judgments entered. The Verbal Comparison Screen as it appears when Judgment 3 is the Current Judgment. When you are finished with a judgment, move to the next cell by clicking in it with the mouse. Move it up if Activities are more important to you and move it down if Nitelife is more important to you. Click with the mouse to move the indicator up and down the scale. The Verbal Assessment Screen where you will make Judgments. To move back to the main screen at any time click the blocks icon for the treeview of the model. 2) Select Assessment then Pairwise from the menu, then select: The verbal assessment screen for the criteria is shown in Figure 2. Use these steps: 1) Move to the Goal Node and click on it. First enter judgments for the importance of the criteria with respect to the goal, then the alternatives with respect to each criterion. MAKING ASSESSMENTS (ENTERING YOUR JUDGMENTS) Move to the goal node to make assessments (i.e. You could also insert subcriteria and sub-subcriteria in the treeview panel as well, but we asked you to keep it simple this time. The alternatives are in the Alternative Panel at the right. The goal and criteria are in the treeview panel at the left. Next you will enter the alternatives, the cities, by selecting Edit Alternative Insert, or by clicking the Add Alternative Icon at the top right of the Alternatives panel. Press to stop the process of inserting criteria. Select Edit then Insert Child of Current Node from the menu type your first criterion and press the key. ENTER YOUR OWN CRITERIA AND VACATION PLACES Enter the Criteria 1. Enter a brief description such as SELECT BEST PLACE TO GO ON VACATION. Enter a name for your model (for example, Vacation). Click on the EXPERT CHOICE icon on the desktop, or select Start, Programs, Expert Choice 2000 and select the Expert Choice 2000 icon. START A NEW MODEL To start a new model, do the following: 1. You might choose from criteria such as cost, night life, friends, shopping, ocean, scuba diving, hiking, golfing, ease of getting to, climate, attractions, etc. We suggest you limit the number of criteria to four, and the places to three or four. Your goal will be to find the best vacation place. You will then synthesize to get your results and perform sensitivity analyses. EXERCISE 1 - CHOOSING A VACATION SPOT In this exercise you will build a model and perform pairwise assessments throughout. 2) You will create another type of model to rate vacation cities against standards you will establish. 1) You will build, make assessments in, synthesize, and perform sensitivity on an EC model to find the best place to go on vacation. 1 EXPERT CHOICE TUTORIAL This tutorial will guide you through two practice problems.
