Taiwanese National Park Headquarters employ advanced information technologies to attract travellers, researchers, and other visitors, but it is likely that not all Headquarters have clear knowledge about how successful their websites are. This study proposes an effective model for evaluating national park websites. The model first applies the Decision-Making Trial and Evaluation Laboratory (DEMATEL) to cope with the interdependencies between evaluation criteria. Next, it uses the Analytic Network Process (ANP) to compute weights for each criterion. Finally, it uses the VlseKriterijumska Optimizacija I Kompromisno Resenje (VIKOR) to rank Taiwanese national park websites. Overall, the results show that each national park website must be improved in order to become a high quality website. Furthermore, the weight-variance analysis suggests managerial actions based on two-dimensional maps for improving website quality. Therefore, this study not only provides a comprehensive and systematic approach that quantitatively measures a website's overall performance, but also contributes to practical applications in terms of providing worthwhile recommendations for building an ideal website.
