Fuzzy Approach In Modeling A Decision Support System With Analytic Hierarcy Process
Introduction
Decision Support Systems (SPK) are interactive tools that help the decision-making process by analyzing various alternative solutions. In many cases, SPK utilizes various methods to achieve optimal results. However, the static SPK model that only considers one event in a particular situation is often less effective in solving complex problems that involve a variety of criteria and varying time. To overcome these limitations, the Fuzzy and Analytic Hierarchy Process (AHP) approach can be combined in building a more comprehensive SPK model.
Understanding the Fuzzy Approach
The Fuzzy approach allows the assessment of criteria to use a triangular fuzzy value, which is able to represent the uncertainty and ambiguity in decision making. This approach is particularly useful in situations where the decision maker is unable to provide a precise value for a particular criterion. By using a triangular fuzzy value, the decision maker can express their preference in a more nuanced and flexible way.
Understanding the Analytic Hierarchy Process (AHP)
AHP is a decision-making tool that helps determine the priority weight of each criterion based on its level of importance. This approach is useful in situations where there are multiple criteria that need to be considered, and the decision maker needs to determine the relative importance of each criterion. AHP uses a hierarchical structure to evaluate the criteria, with the most important criterion at the top of the hierarchy.
Combining the Fuzzy and AHP Approach
By combining the Fuzzy and AHP approach, the SPK model produced can provide more accurate and effective results. The following are the steps for implementing the Fuzzy and AHP approach in SPK:
Formation of the Fuzzy Decision Matrix
Every alternative is evaluated against each criterion using a triangular fuzzy value. This Fuzzy Decision Matrix represents the decision maker's preference for each alternative based on predetermined criteria.
Determination of the Weight Vector with AHP
AHP is used to determine the priority weight of each criterion based on the level of importance.
Alternative Priority Value Calculation
The priority value of each alternative is calculated by multiplying the fuzzy value in the decision matrix with the weight vector obtained from AHP.
The Best Alternative Selection
Alternative with the highest priority value was chosen as the best alternative.
Advantages of the SPK Fuzzy-AHP Model
The main advantages of the SPK Fuzzy-AHP model are:
The Ability to Handle Uncertainty
Fuzzy approach is able to manage uncertainty and ambiguity in decision making, which often occurs in the real world.
Priority Criteria Clear
AHP allows the determination of priority criteria that are clear and measurable based on decision makers' preferences.
More Accurate Results
By combining the two approaches, the resulting SPK model is more accurate and objective in determining the best alternatives.
Examples of Application
Imagine a company that wants to choose a new location for the branch office. Criteria considered include rental costs, transportation access, and market potential.
Fuzzy Approach
Each location is assessed for each criterion using a triangular fuzzy value. For example, location A has a "low" rental fee, "medium" transportation access, and the "high" market potential.
AHP
Criteria for rental fees are considered the most important, followed by transportation access, and then market potential. This is reflected in the weight vector obtained from AHP.
Conclusion
The Fuzzy and AHP approach offers effective solutions in building SPK models that are able to handle uncertainty and provide accurate results. The application of the Fuzzy-AHP SPK model allows more structured, objective, and appropriate decision making, thus improving the quality and efficiency of the decision-making process in various fields.
