Design and Implementation of a Fuzzy-Event Driven Simulator

Inter dependencies among infrastructure elements are intertwined and complicated. Understanding cascading effects because of direct or indirect interdependencies is critical and necessary for the effective response and management of social resources, especially in a disaster or emergency. Modelling cascading processes has attracted more and more concerns and become an emerging interdisciplinary field of study. This paper, from the view of software engineering, introduces a fuzzy-event driven algorithm, designs the modular prototype structure and domain object models of one fuzzy-event driven simulator to model cascading processes among entities, and also specifies multithreading implementation strategy and development environment. Finally, an example is included as an illustration as well. This study can help people understand potential cascading effects, and eventually find out the vulnerable components for decision-analysis.
