Abstract

Cost-benefit analysis is a benefit measurement method that compares the cost required to realize the product, service or result with the benefits to be obtained. It allows future earnings to be calculated with the present value of money and different projects can be compared. In this study, the uncertainties of decision maker inputs were reflected in a more realistic way by dealing with the cost-benefit analysis under decomposed fuzzy sets. The contribution of this study to the literature are the decomposed fuzzy linguistic term scale, which is proposed for the first time, and the new equations and formulations developed for cost-benefit analysis under fuzziness. This study also contributes to the successful applicability of engineering economics issues and financial analysis methods under fuzziness.

摘要

成本效益分析是一种效益衡量方法，将实现产品、服务或结果所需的成本与将要获得的效益进行比较。它允许用货币的现值计算未来收益，并且可以比较不同的项目。在本研究中，通过处理分解模糊集下的成本收益分析，更真实地反映了决策者输入的不确定性。本研究对文献的贡献是首次提出分解的模糊语言术语量表，以及为模糊下的成本效益分析开发的新方程和公式。本研究也有助于模糊下工程经济学问题和财务分析方法的成功应用。
