The medical skills in some developing countries are almost as advanced as those in developed countries. Medical cost, however, is relatively lower in the developing countries. In recent years, the medical industry in some developing countries has exhibited the trend of providing international medical services. Taiwan's medical quality and instruments are at par with those of most developed countries. The average medical cost is relatively more reasonable. Generally, the infrastructure in Taiwan is at a respectable level to be able to develop international medical treatment and to offer short-term vacations. Furthermore, an oversea tourist will require specific post-cosmetic care after he/she had finished the cosmetic treatments and preferred to have a short-term vacation in that area. Generally, the post-cosmetic care during the vacation is important to effectiveness of the cosmetic treatments. In this paper, we aim to explore technical models for serving the overseas tourist and realizing the collaborative business services of cosmetic treatments and travel tourisms. The proposed Cosmetic Tourist Guiding Model (CTGM), which includes the Genetic Algorithm (GA) scheduling function for planning suitable trips and remote pre-assessable functions, can provide overseas visitors convenient services and allows the cooperation of business owners of medical treatment facilities and travel agencies.
