Abstract
We propose a decision-making framework on infrastructure policy conflict management based on a scientific approach. We developed a decision-making framework that consists of the systematic conflict structure diagnosis, decision-making accordingly, and feedback to be used consistently in the policy life cycle and applied it to new airport projects in South Korea. We suggested a model structure of conflict factors leading to the generation of conflict situations and damages in the process and developed the conflict level diagnosis table and the conflict level matrix formed of the possibility of conflict generation and the severity based on the table. We then implemented a decision-making framework that includes decision-making based on it. The case analysis results confirmed the need for a structural diagnosis of conflict and decision-making based on the framework. The developed framework is expected to have scalability for science progress on infrastructure policy conflict management.
