To add a new decision matrix, click on the button on the main screen toolbar. To edit the data of a decision matrix, select it in the list of records and click on the button.

On the screen that will be opened, enter an ID # and a name for the decision matrix. The following tabs are also available:

matriz_decisao_dados

Note: To successfully add a decision matrix, it is necessary to fill out the required fields in the General tab. At this point, the other tabs will be enabled to be filled out.

General

Field
Responsible team	Select the team that will be responsible for the decision matrix. The decision matrix will only be displayed in the list of records on the main screen, for the team members selected in this field. Use the other buttons next to the field to add a new responsible team and associate it with the matrix and clear the field.
Comments	Fill out this field to enter important information about the decision matrix.

Alternative

Use this tab to associate the possibilities available for decision making. To do that, use the following buttons of the side toolbar:

Click on this button and select the desired option:

▪New: On the screen that will open, enter an ID #, a name and a description for the alternative that you wish to add to the decision matrix. After that, save the record.

▪Import: On the screen that will be open, locate and select the alternatives of other decision matrices created in the system which you wish to use in the decision matrix in question.

Click on this button to edit the data of the alternative selected from the list of records.

Click on this button to delete the alternative selected from the list of records.

Criterion

Use this tab to define the criteria that will be used to consider the alternatives previously added. To do that, use the following buttons of the side toolbar:

Click on this button and select the desired option:

▪New: On the screen that will open, enter an ID # and a name and assign a weight (value) to the criterion. In addition, describe the criterion that you wish to add to the decision matrix. After that, save the record.

▪Import: On the screen that will be open, locate and select the criteria of other decision matrices created in the system which you wish to use in the decision matrix in question.

Click on this button to edit the data of the criterion selected from the list of records.

Click on this button to delete the criterion selected in the list of records.

Consequence

This tab will only be enabled after entering the criteria and alternatives. The list of records in the lower part will display, as a matrix, the alternatives and criteria added to the previously described tabs.

For each alternative, it is possible to assign a score, at a proportion that will meet each criterion, that is, assign a score to the consequence of the implementation of this alternative in the criterion scope. To do this, click on the button and, on the screen that will be displayed, enter the desired score (value). If necessary, it is possible to enter comments regarding the given score.

In the Decision-making method field, set how the weighted score will be obtained:

▪Sum: The system will multiply the value of the consequence of each alternative by the weight of each criterion, thus obtaining the weighted score. Then all the weighted scores obtained for each alternative will be summed up.

▪Average: The system will carry out the weighted average of the alternatives in relation to the criteria. That is, multiply the value of the consequence of each alternative by the weight of each criterion. Then, all the obtained weighted scores will be added and the result of this sum will be divided by the result of the sum of the weights of the criteria.

▪Pessimistic: The system considers, as a result, the consequence of the alternative with the least value.

▪Optimistic: The system considers, as a result, the consequence of the alternative with the highest value.

Then, click on the button, present next to the field. The Result column will display the result of the selected method. The alternative with the highest result value can be considered the best alternative.
