A fuzzy multiple attribute decision making model for benefit-cost analysis with qualitative and quantitative attributes

Abstract

In this paper, a fuzzy multiple attribute decision making model to solve the mutually exclusive project selection problem with qualitative and quantitative attributes in benefit-cost analysis is proposed. The quantitative values such as investment cost, annual income and so on could be crisp or fuzzy numbers. Also, the qualitative attributes and their information are defined in fuzzy environment. By applying fuzzy set theory, we aggregate the qualitative and quantitative attributes with each other through some multiple attribute decision making models to select the best alternative for investment.
