Abstract

Financial feasibility studies are paramount for the successful development of large-scale infrastructure projects, such as Drinking Water Supply Systems (Sistem Penyediaan Air Minum - SPAM). However, these studies are often plagued by inherent uncertainties and imprecisions in various financial parameters, leading to potential inaccuracies in traditional evaluations. This article explores the application of fuzzy logic methodologies to enhance the robustness and realism of financial feasibility assessments for water supply infrastructure development. Traditional deterministic approaches, which rely on crisp numerical values, are often inadequate for capturing the subjective and imprecise nature of future costs, revenues, and economic conditions. Fuzzy set theory provides a powerful framework to model and incorporate these uncertainties, offering a more nuanced and realistic evaluation. By reviewing the principles of fuzzy finance and outlining a methodological framework for integrating fuzzy logic into key financial metrics like Net Present Value (NPV) and Internal Rate of Return (IRR), this study demonstrates how fuzzy methods can provide more robust decision-making support for project developers and investors, particularly in dynamic and uncertain environments. The approach aims to provide a more comprehensive understanding of financial viability, moving beyond single-point estimates to embrace ranges and degrees of possibility.
