MARITIME SECURITY-ASSESSMENT AND MANAGEMENT

摘要

After the tragedy of September 11, 2001, there is widespread concern in the international society that a terrorism organisation capable of the suicide hijackings of airliners could readily adapt these capabilities to major shipping targets. Techniques require to be developed to bridge maritime security gaps, which are defined as the potential areas associated with how to assess the security levels of a vulnerable maritime target and how to use the assessment to make appropriate decisions and controls. Some safety experts have focused their mind and attempted to use traditional risk assessment and decision making approaches to deal with possible terrorism threats in a maritime security area, investigate the key vulnerabilities and provide effective security control and management options. Two of the major challenges are to analyse security in situations of a high level uncertainty and to construct all information available with difference in nature in a utility form suitable as input to a risk inference mechanism. To solve such difficulties, this paper proposes a subjective security-based assessment and management framework using the combination of two fuzzy evidential reasoning (ER) approaches.
