Benefit Evaluation of the Recreation Facility Constructing by Using Fuzzy Utility

Abstract

We have two important assumptions, the perfect imformation and the rational behavior, when we evaluate the infrastructure constructing by the ecobomic theory. But we think there is always fizziness in those behaviors. In this paper, we built the benefit evaluation model by using the fuzzy utility, in order to consider the fuzziness of decision-making, We introduced the fuzziness for the utility maximizing behavior in the general equilibrium model, and showed the possibility to measure the benefit as fuzzy. We carried out the simulation analysis for the assumption case. Though we set the 1% fuzziness, the benefit had the large width. We must plan the policy as being care for its facts.
