| Summary: | 碩士 === 中央警察大學 === 警察政策研究所 === 107 === This study conducts the research on the construction of critical infrastructure information sharing platform. Through reviewing domestic and international literature and Multiple Criteria Decision Making (MCDM) methodology, this study looks for the success factor indexes of critical infrastructure information sharing platforms, and analyzes by means of the “Consistent Fuzzy Preference Relation, CFPR” proposed by scholars such as Herrera-Viedma, in order to understand the relative importance of the success factors of information sharing platforms between the dimension and indicator, and to explore the success factors to establish the information sharing platform. According to relative literature reviews, five major dimensions (information sharing capacity, security of information sharing platform, information sharing mechanism, internal system, and external environment) and 22 factor indicators are found closely related to the critical infrastructure information sharing platform. Therefore, this study had invited a number of scholars and practitioners with the background of homeland security, critical infrastructure protection, information sharing, and information security to be surveyed an expert preference analysis questionnaires and calculated the weight of each dimension and factor indicator. Through multi-objective decision analysis, it is found that the ability to analyze information is the most important factor in constructing a critical infrastructure information sharing platform, followed by information access control and establishing a cross-field coordination mechanism. According to this study, appropriate suggestions are proposed, including: (1) to enhance the country’s overall crisis awareness and emergency response; (2) to strengthen the information analysis ability; (3) to emphasize the communication among the critical infrastructures in various fields and public and private sections; (4) to ensure the security of information communication; (5) to balance the homeland security and human rights protection. Due to the limitation of manpower and time, the questionnaires were issued only to domestic experts and scholars. In the future, it is expected to expand the viewpoints from the practitioners and foreign experts and scholars, and continue the qualitative interview on the information sharing platform to explore a deeper content.
