Abstract.
In the paper the basic reliability structures of complex tech-
nical systems were described. Selected models of the reliability structure
were presented. This original paper is a proposition of using reliability
structures and based on them algorithms to ensure better diagnostics,
maintenance and control of complex technical systems. Some practical
examples of using reliability structures were indicated. The presented
structures can be put into use in human-machine interfaces to inform
operators about the current system condition and to automate some en-
gineering processes and procedures concerning the system reliability.
Keywords:
HMI (Human-Machine Interface), reliability structures,
fault detection, diagnostics.

Introduction
Based on the concept of the general system, which was developed by the Aus-
trian biologist Ludwig von Bertalanffy in the 30s of the last century, the technical
system can be represented as an object treated as a set of functional elements.
It consists of components called elements which mutually cooperate in the im-
plementation of defined functions of the system. The elements are indivisible in
the analysis of the decomposition level.
The system is a functional unit that is subjected to a bi-directional interaction
with the environment. It is described as an ordered pair
E,U
consisting of a
set of elements E and a sequence U defining specific relationships between the
elements. Sequence U is defined as the structure of the system.
