A Satisfaction Evaluation Method for Scenic Spot based on Linguistic Weighted Arithmetic Average Operator

Abstract

Based on the level empowerment system and the linguistic operator, a satisfaction evaluation process is proposed in this paper. First of all, a level empowerment system is established to generate the weight of each surveyed tourist. Then, some new linguistic operations are defined which can remedy the defects of the existe d operations. Besides, the expectation and variance in linguistic information environment are defined to generate the weight of ea ch character of tourist and the weights of indicators, and linguistic weighted arithmetic average (LWAA) operator is introduced to aggregate the linguistic information of each touris t and the group linguistic information of each indicator. Finally, a satisfaction evaluatio n case is illustrated to explain the evaluation process.
