MODELING SAFETY OF MULTISTATE SYSTEMS WITH APPLICATION TO MARITIME FERRY TECHNICAL SYSTEM.

- Abstract
Basic notions of the ageing multistate systems safety analysis are introduced. The system components and the system safety functions are defined. The mean values and variances of the multistate system lifetimes in the safety state subsets and the mean values of its lifetimes in the particular safety states are defined. The notions of the multi-state system risk function and the moment of exceeding by the system the critical safety state are introduced. A series and a parallelseries safety structures of the multistate systems with ageing components are defined and their safety function are determined. As a particular case, the safety functions of the considered multistate systems composed of components having exponential safety functions are determined. An applications of the proposed multistate system safety models to the prediction of safety characteristics of a maritime ferry operating at winter conditions technical system is presented as well.
