Early Warning Index System of Vulnerability for Overseas Port Built Project

Vulnerability evaluation is the basis of effective early warning and restoration of inherent defects, so it´s of great theoretical and practical significance to establish an early warning index system of vulnerability for overseas port built project (OPBP). Firstly, some foundation research about the vulnerability of OPBP was carried out, including the relationship between the internal vulnerability and external risks of the project, the types of risks and vulnerability of OPBP, the model frame and operation mechanism of vulnerability of OPBP. Then, an early warning index system was established. This system was a multi-level index system, and mainly evaluated by the vulnerability of elemental management and the vulnerability of functional management and their sub index. The establishment principles and significance of the index system were discussed. Then, the fuzzy comprehensive evaluation method was used to confirm the index weight and the index value. Finally, a case study on the Jeddah port project in Saudi was conducted.
