![]() The slowly increasing application of the AHP was the motivation for this study to explore the current state of its methodology in the healthcare context. The weight for each criterion and alternative are judged in pairwise comparisons and priorities are calculated by the Eigenvector method. The AHP disaggregates a complex decision problem into different hierarchical levels. The Analytic Hierarchy Process (AHP), developed by Saaty in the late 1970s, is one of the methods for multi-criteria decision making. (2006) Analytic Hierarchy Process (AHP) Tutorial. Preferable reference for this tutorial is To purchase the PDF copy of this AHP tutorialĭo you have question regarding this MCDM tutorial? Ask your question here They are depending on you as decision maker. ![]() Now you see that not only the criteria and alternatives are subjective, even the values are also subjective. Higher value indicates higher level of the factor or preferable values. The values can be any number with order (ordinal number) and you can even put different range for each factor. The values are number within any certain range say from 1 to 10 or -5 to 5. As we try to make our decision as rational as possible we need to quantify these subjective opinions into subjective Most of decisions makings are based on individual judgments. Some factors may be combined together and some criterion may be broken down into more detail criteria. Different people may add or subtract those lists. There is no correct or wrong criterion because it is subjective opinion. They neither cover all possible criteria nor all possible alternatives. Notice that the list of criteria and alternatives above are not exhausted list. The determination of criteria and alternatives are very subjective. Total cost (capital, maintenance, operational) Table 1: Example of Goal, Criteria and AlternativesĬar's trade mark (Honda, GM, Ford, Nissan etc.)ĭecide whether to buy or to rent a machine Table 1 below shows example of criteria and alternatives of several decision makings. Similarly, I use 'alternative' and 'choice' for the same meaning. ![]() In this tutorial, I will use the word 'factors' and 'criteria' interchangeably. On group decision making these criteria and alternatives are more obvious and must be determined first before we give some judgment score or evaluation values on them. On what to consider and we also have severalĬhoices that we should decide. In each of these decisions, deep in our mind we have several factors or We decide which school to take, which place to live, which clothes to use, which persons to be our best friends or to marry, which food to eat, which car to buy, and so on.ĭecision making is process to choose among alternatives based on multiple criteria. In this section of tutorial, you will learn background materials with several terminologies such as criteria or factors, alternatives choice, evaluation score value and weight of importance level and how to transform different range of judgments into fair evaluation. ![]()
