Analytic Hierarchy Process
An Overview
Methodology• The Analytic Hierarchy Process (AHP)
– How AHP Structures Decision Problems • Overall Goal• Criteria• Alternatives
– Facilitates Decision Analysis
• Measures the Extent to Which Each Alternative Achieves Each of the Criteria
• Determine the Relative Importance of the Criteria in Meeting the Goal
Analytic Hierarchy Process
Complex Decisions Conflicting Multiple Objectives Differing Perspectives
The Recommendations Offered by Decision Analysis Should Not be Blindly Accepted.
Methodology
1. Determine the Weights of the Alternatives for Each Criterion
2.Determine the Priorities or Weights of the Criteria in Achieving the Goal
3.Determine the Overall Weight of Each Alternative in Achieving the Goal. This is Accomplished by Combining the Results of the First Two Stages and is Called Synthesis
The Analytical Hierarchy Process Using Expert Choice
• Expert Choice is a decision-making software program that utilizes AHP
• Certain Criteria are chosen based on relevant importance and personal preference
• Example: What is the Best Car to Buy?
Expert Choice
