A Fuzzy Model for a Railway-Planning Problem

This paper discusses the issue of how to solve multi-criteria decision making (MCDM) problems by applying fuzzy logic. Multicriteria decision-making problems often involve a complex decision process in which multiple requirements and fuzzy conditions have to be taken into consideration simultaneously. Fuzzy set theory provides the mathematical technique for the systematic handling of imprecise data. This paper outlines an evaluation-framework which integrates fuzzy logic with multi-criteria decision-making in the context of an infrastructure planning. Furthermore, the proposed approach is applied to a real decisional problem connected to the planning and construction of a new railway link to demonstrate the applicability of the proposed method. The study results show that this method is an effective means for tackling MCDM problems in a fuzzy environment.
