A Computational Model of Trust Based on a Multi-Criteria Decision-Making Approach

In this paper, we try to formulate trust as a multi-criteria decision making process. Making trust decisions needs a struc-tural way in computational domains. Based on this need, we use a combination of fuzzy AHP and fuzzy VIKOR approach from the domain of Multi criteria decision making to formulate trust. VIKOR method was originally developed to solve decision prob-lems with conflicting and non-commensurable criteria. By using the VIKOR approach, we can rank the trustee alternatives and determine the compromise solution that is closest to the ideal. Combining fuzzy logic with this approach lets us model the vague, uncertain and subjective nature of trust.
