A Pictorial Guide for the Fuzzy DEMATEL Online Software
Working with fuzzy DEMATEL software is very simple: (1) Define the number of criteria (2) Create /select a fuzzy scale (3) Enter pairwise comparisons (4) Get the full output
1. Enter the project name
First of all, enter your project name.
For example, in this project, the fuzzy DEMATEL method is applied to select the best College.
2. Project Specifications
Here, you can define the number of criteria.
Enter each criterion in the column of the table, and then click on the button “Create Table of Criteria”. This will create a table of criterion specifications.
To select the desired name for the criterion, click on the criterion name and enter your own desired name that is short to write.
3. Select /create the fuzzy scale
Here, you can select or create your own fuzzy scale from a list of default fuzzy scales.
You can select your own default fuzzy scale from a drop-down list.
Select your own fuzzy scale from a list of the default scales.
If you tend to create your own fuzzy scale, click “Create Scale” and create your own fuzzy scale in the table.
To create a new scale, you need to enter your own linguistic terms and fuzzy triangular numbers. The triangular fuzzy numbers can be characterized as l, m, u, which represent the lower, middle, and upper values, respectively.
As shown on the picture, you can easily edit a scale
4. Enter the pairwise comparisons
Here, you can fill the pairwise comparison matrices based on the number of criteria.
A number entering each cell of the matrix indicates that a row criterion is more important than the column criterion
Note that in the pairwise comparison matrices, the codes that appear in the scale table need to enter (A code represents a verbal expression, for example, code 5 implies the high importance).
To fill the pairwise comparison matrices, simply click in each cell of the matrix and enter your own scale code.
It is recommended that you enter codes in Excel in order to avoid wasting time, and then copy and paste tables from Excel at once.
As you can see on the picture above, experts include the following:
Add Expert: If there are several experts, you can increase the number of experts by clicking “Add Expert”. The previous expert will be automatically saved by clicking on the button “Add Expert” and the new expert will be added.
Delete Expert: The current expert will be deleted by clicking on the button “Delete Expert”.
Save Expert: The data of current expert will be saved by clicking on the button “Save Expert”.
The experts’ Status: The experts’ Status will be displayed by clicking on the button “The experts Status”
Mean: The fuzzy average of all the experts will be observed by clicking on the button “Mean”.
As you can see in the picture below, the experts’ status include the following:
If all the expert data are completed and saved, the expert’s status is “completed”.
If all the expert data are not completed, the expert’s status is “incompleted”.
If an expert has been deleted, the expert’s status is “deleted” and you can recovery data.
To observe the mean, the data of all current experts must be completed.
5. Get the full output
You can get the full output of the fuzzy DEMATEL method. Here, there are all the steps of the fuzzy dematel method along with the related tables or formulas.
6. Download EXCEL and WORD
Here, you can download the Word report file, Excel file and input data.
