About Analytic Hierarchy Process
The Analytical Hierarchy Process (AHP) produces a reliable and precise prioritization or ranking of customer requirements or other items.
Weight requirements by efficient pairwise comparison
An AHP returns a Pareto diagram of requirements, with item weights adding up to 100%.
How to insert the Analytic Hierarchy Process component
The Analytic Hierarchy Process template can be used to start new projects or to extend existing projects. Please read chapter "The Templates" to learn more about how to start new projects.
In order to extend your project:
- Activate the Home Ribbon
- Click the Add Tool button on the Home ribbon
- Click the Analytic Hierarchy Process icon in the template catalog
In order to find the Analytic Hierarchy Process component within the template catalog, you have to choose a cycle name on the first line of the screen and a phase name at the left of the screen. The Analytic Hierarchy Process component is located in this cycle/phase combinations:
- DFSS DMADV: MEASURE
- DFSS IDOV: IDENTIFY
Analytical Hierarchy Process (AHP) for Voice of Customer (VOC) prioritization
The AHP module provides an easy way to create the AHP matrices for VOC or any other tree. It calculates importance values and consistency indexes for each sub-matrix. Additional worksheets help to gain data from a questionnaire or fill out the matrices systematically during team sessions.
Inserting an AHP for Functions, Components or any other Tree
If you follow the steps on inserting the AHP component, it will try to link to the VOC tree. You can also link the AHP to any other tree in your project:
- Select the target tree or an item in the target tree on any worksheet in your project.
- Follow the steps to insert the component
Structuring Data
An AHP can only work properly, if the criteria are sorted into groups with nearly equal number of items. For good results, try to find groups with not more than 9 elements each. It is also possible to build groups, subgroups and leaf items or even deeper tree structures.
If you expand the AHP's main worksheet in the project browser, the first sub-worksheet is well suited to do the grouping and sorting of the criteria. Of course, you can also use the Mind Map / Ishikawa component to create the criteria tree.
Worksheets
The AHP Worksheet
The AHP component's main worksheet contains everything to fill out and calculate the AHP prioritization.
Group Selector
Select the focused group by clicking the drop down button or the scroll buttonsVOC / Criteria
This section shows the items inside the selected groupAHP Matrix
Enter the comparison values. Clicking into a cell will open a menu to choose from. Use keyboard input 1...9 if the left element is more important or Shift+1...9 if the left element is less important than the top element. Opposite (reciprocal) values are calculated automatically. Press F5 to start calculation. After calculation, items are sorted by importance. This helps to eliminate inconsistencies. Sorting can be changed or stopped using Sort from the Home ribbon.Importance in Group
This section shows the calculated importance in percent for the focused group.Bar Chart
This chart shows the calculated importance as bar graphs. A confidence interval can appear as black line inside each bar.Consistency
This section shows the calculated consistency index. A consistency index of 0 shows that the matrix is completely consistent.
