On the present state-of-the-art of a component importance analysis for complex technical systems

The paper presents the present state-of-the-art of a component importance analysis for complex technical systems. We used a sea vessel as an example of the complex technical system. We showed selected statistics of ship operation losses. We highlighted a necessity of further development of importance analysis methods for machinery operation. We presented a description and diagrams of qualitative and quantitative importance analysis. We pointed out the most significant problems of complex technical systems modelling. We introduced a multi-criteria system component importance analysis. Basic criteria for a system component quality evaluation have been presented. We described some factors influencing importance of the technical system components.
