Robustness Criteria for Safety Enhancement of Ship’s Structural Components

The paper describes an application of the probabilistic event oriented system analysis to the design of ship structural components with the aim to evoke the possible usage of reliability theories in the design practice. The basic concepts of events analysis and of system robustness are summarized at the beginning. The system robustness takes on the entropy concept in probability and information theory in order to ensure the most uniform distribution of safety of failure events of structural components in ship’s service. At the end, the paper presents in details an example of robustness maximization of a typical ship structural component under number of design failure criteria. The example corroborates that it is possible to fi nd structural confi guration with more uniform distribution of safety on the basis of robustness criteria.
