Abstract
The tourist industry needs to increase the competitive power. Authors advance the collaborative research that tries to attract foreign tourists. My part on the collaborative research is to propose tour design method that can correspond to various needs of customer. To attain the aim, three conditions are required. The first is to design the platform that can supply various tours. The second is to reduce operation costs. The third is to guarantee implementation of tours. This paper focuses on the third element and proposes information model for tour service design considering service constraints. The model represents three constraints that tours should fulfill. Based on the calculation of these constraints, feasibility of tours is judged.
