Abstract Risk Analysis of Ship Hull Vibration Using Evidential Reasoning

A subjective approach incorporating Evidential Reasoning (ER) algorithm is developed in order to achieve the risk analysis of Ship Hull Vibration (SHV). A hierarchical process is developed using the available data of the issue, then the qualitative and quantitative criteria are applied as one of the steps to obtain risk analysis. The quantitative criteria are converted to the qualitative ones by applying a rule based quantitative data transformation technique to make use of the ER and quantified qualitative assessments, which is employing the mapping process to determine an aggregated value for each alternative. The risk analysis of SHV is produced graphically by using the IDS (Intelligent Decision System) software. The results of this research reveal that the ER is applicable to obtain risk analysis of SHV
