On Ship Systems Multi-state Safety Analysis
1 Gdynia Maritime University, Gdynia, Poland
ABSTRACT: A multi-state approach to defining basic notions of the system safety analysis is proposed. A system safety function and a system risk function are defined. A basic safety structure of a multi-state series system of components with degrading safety states is defined. For this system the multi-state safety function is determined. The proposed approach is applied to the evaluation of a safety function, a risk function and other safety characteristics of a ship system composed of a number of subsystems having an essential influence on the ship safety. Further, a semi-markov process for the considered system operation modelling is applied. The paper also offers an approach to the solution of a practically important problem of linking the multi-state system safety model and its operation process model. Finally, the proposed approach is applied to the preliminary evaluation of safety characteristics of a ship system in varying operation conditions.
