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.}, issn = {2083-6473}, publisher = {Gdynia Maritime University, Faculty of Navigation}, keywords = {Safety at Sea, Marine Navigation, Sea Transportation, Semi-Markov Process, Multi-State Safety Function, Safety Analysis, Ship Operation Process, Complex Multi-State System} }
