Methodological prerequisites to estimation of electric machine maintainability
Methodology allowing estimating electric machine maintainability from the point of view of system analysis has been given. Uncertainty of information data occurring at operation of electric machine was considered. Aim decomposition which is reflected in the form of "tree of objectives" was carried out for efficient maintenance and service of electric machine. The obtained results may be used as initial data for statement and solution of a number of tasks of controlling electric machine maintainability.
