ABSTRACT
During the operation of complex technical systems it is often required to identify the element or device that plays the most important part in the system. This also applies to marine oily water purification systems. In order to determine accurately the degree of validity of the elements in the system, the so called elements validity measurements have been constructed. Selection of an appropriate measurement for a specific practical application largely depends on the fact, what aspect of the element validity is in this case most important. The following measures are considered: Birnbaum reliability measurement, Birnbaum structural measurement, Vesely-Fussell validity measurement, the critical measurement, potential for improving the reliability, measures of validity independent of time, the Barlow and Proschan measurement, Lambert measurement. The author proposes using a method based on the evaluation of the amount of streams of energy factors flow through individual elements (devices) in the functional structure of the technical system. The validity and importance of the element in the system is evaluated based on the amount of streams of energy factors that flow to and from the element. The greater the number of these streams, the more responsible the element for the operation of the system in this state is. The validity of an element in the structure is described by the total sum of streams of energy factors (the stream measurement), which flows to and from the element.
