Fuzzy Financial Profitability Analyses of Demand Side Management Alternatives

This paper derives fuzzy profitability models for the financial evaluation of different demand side management (DSM) alternatives. The present value of cost (PVC) and equivalent uniform annual cost (EUAC) models are selected to determine the least-cost solution, while the net present value (NPV) and benefit/cost ratio (BCR) models are proposed for the execution of cost-benefit analysis. The performance of the proposed models is verified by considering their application to two practical DSM programs in Taiwan. These investigations confirm not only that the results of the proposed fuzzy economic models are consistent with those of the conventional crisp models, but also demonstrate that the proposed methods represent readily implemented possibility analysis tools for use in the arena of uncertain financial decision-making
