Vužití fuzzy spolehlivosti pro technické systémy

Abstract

The key part of this work is concerning about solution of industrial systems reliability. It is exploiting input data obtained by conventional methods of reliability analysis and evaluation by probability theory and statistical methods. Combining those with fuzzy reliability tools and sets it is qualifying feasibility of fuzzy approach for reliability evaluation. Labor models fuzzy model structure corresponding to the structure of an industrial object, so that the conditional reliability of individual units corresponding to relations of blocks and there is ready to simulate them. Introduction of this subject is focused at getting acquainted with the tools of standard reliability tools and methods for data mining, analysis and evaluation of reliability indicators together with supporting mathematics. Next section explains and applies algorithm development of modelling. Then continue with various methods of fuzzy reliability simulation. Next it implements the model solving the problem by using fuzzy reliability principles used to demonstrate the calculation carried out by this method. Work refer to advantages and disadvantages of solving task by fuzzy reliability approach compare to use different methods- standard failure probability and reliability assignment and calculation.
