Abstract
This chapter develops a novel fuzzy evidential reasoning (FER) approach to facilitate the quantitative analysis of PFSA and to rationalize port security inspection and auditing practice. It explains the need for effective port inspection and auditing, and also describes the requirements for PFSA under the ISPS Code’s regime. After then, the chapter illustrates and explains the novel PFSA methodology, including the supporting model, while its feasibility is also illustrated.
