An analysis by QFD has been made on the principles of tourism product designs, followed by the introduction of such new concepts as expected service quality and perceived service quality from the perspective of customer perceived service quality. Based on the analysis of the six elements of tourism service, a research has been conducted on alternatives for the achievement of these elements. A proposal has thus been made of a multi-objective optimal design model of tourism product with the highest tourist satisfaction and the lowest design cost, taking into consideration the alternatives for different tourism elements. Finally, a case study has been made on the optimization design of a tourism product, and an analysis has been made of the option of the target model under different weights, thus verifying the feasibility and effectiveness of the proposed method.
