Identification of Key Causal Chains of Ship Collisions Based on Cascade Failure
In order to reveal the evolution pattern of ship collision causes and effectively prevent ship col-lision accidents,this paper proposed a key causal chain identification method based on the cascade failure the-ory.Firstly,the causal factors of ship collision are abstracted into a network model.Secondly,the causal chain identification method based on the cascade failure theory is designed.Finally,100 ship collision accidents are used to analyze this method in a case study.The results of the case study show that this method can effectively identify the key causal chains of ship accidents.It can provide some theoretical basis and decision support for ship demand priority management.
