This paper presents Failure Mode and Effects Analysis using relations diagrams and matrices similarity method application on the hydraulic cylinder. Functions for each hydraulic cylinder components were identified as well as a pairs for interacting components. Also potential failures were defined. Using the principle of matrices similarity the rank of hydraulic component due to performed functions has been prepared.

The paper presents an identification of potential causes and effects of failures of a coolant pump for internal combustion engines. Ishikawa's quality improvement tools have been used to analyze the defects. The main causes of pump failures and cause-effect relationships have been identified. The main causes were identified and classified in order to select those which have the greatest influence on pump damage during operation.

This paper presents Failure Mode and Effects Analysis (FMEA) on the hydraulic cylinder using matrix analysis and artificial neural network. Functions for each cylinder components were identified. Also relationships between pairs for interacting components and their potential failures where identified. Training and testing of an artificial neural network was conducted in MATLAB software environment.

This paper presents an FMEA analysis of turbochargers for combustion engines by the use of the similarity method and dependency diagrams. Typical functions of selected components of turbochargers were defined and the dependency between them identified. Potential failures that may appear during operation have also been defined. Using the principle of similarity, potential failures have been defined and classified.

W artykule przedstawiono macierzową analizę FMEA siłownika hydraulicznego dwustronnego działania.
Dokonano dekompozycji, zidentyfikowano podstawowe funkcje i potencjalne wady dla relacji para–funkcja. Określono elementy, które charakteryzują się największym prawdopodobieństwem wystąpienia wad i wyznaczono związki przyczynowo-skutkowe.

W pracy przedstawiono analizę użyteczności wybranego serwisu internetowego przy wykorzystaniu jakościowej metody QFD. Zidentyfikowano wymagania użytkowników oraz związane z nimi parametry techniczne tworząc diagramy podobieństw i zależności. Opracowano zarówno wykresy przedstawiające
wyniki benchmarkingu użytkownika oraz benchmarkingu technicznego, jak i wykresy wartości docelowych obliczone dla wymagań użytkownika i parametrów technicznych.
