Structure Analysis of Ship’s Collision Causes using Fuzzy Structural Modeling

Abstract

The prevention of marine accidents has been a important topic in marine society for long time, and various safety policies and countermeasures have been developed and applied to prevent those accidents. In spite of these efforts, however, significant marine accidents have taken place intermittently. Ship is being operated under a highly dynamic environments, and many factors are related with ship’s collision, whose factors are interacting. So, the analysis on ship’s collision causes are very important to prepare countermeasures which will ensure the safe navigation. This study analysed the ship’s collision data over the past 10 years(1991-2000), which is compiled by Korea Marine Accidents Inquiry Agency. The analysis confirmed that ‘ship’s collision’ is occurred most frequently and the cause is closely related with human factor. The main purpose of this study is to analyse human factor. For this, the structure of human factor is analysed by the questionnaire methodology. Marine experts were surveyed based on major elements that were extracted from the human factor effecting to ship’s collision. FSM has been widely adopted in modeling a dynamic system which is composed of human factors. Then, the structure analysis on the causes of ship’s collision using FSM are performed. This structure model could be used in understanding and verifying the procedure of real ship’s collision. Furthermore it could be used as the model to prevent ship’s collision and reduce marine accidents.
