Abstract

Much of the available data associated with seaport operations is uncertain and ambiguous, requiring an approach capable of handling both quantitative and qualitative information. Conventional risk modelling approaches are considered to be inadequate in many circumstances due to the lack of flexibility and an inappropriate structure for addressing the system’s risks. This paper proposes a flexible risk assessment approach to facilitating the treatment of uncertainties in seaport operations in a systematic manner. The methodology consists of a fuzzy analytical hierarchy process, an Evidential Reasoning (ER) approach, and fuzzy set theory. The fuzzy analytical hierarchy process is used to analyse the complex structure of seaport operations and determine the weights of significant risk factors while ER is used to synthesise them. The methodology provides a framework for collaborative modelling of the system and allows for a step by step analysis. It could provide managers and infrastructure analysts with a flexible tool in order to enhance the resilience of the seaport system.
