Creating a comprehensive reliability model of a complex technical object is an objectively difficult task. The main difficulty arises from the wide variety of failure physics. The factors and processes that affect operational reliability and operational efficiency of a complex technical object are characterized by considerable diversity. Furthermore, these disparate factors and processes influence each other, making their inclusion in a single model even more difficult.

The paper examines the possibilities of using graph theory to capture the diverse factors and processes affecting the reliability of objects. In the case of complex technical objects, this diversity is significantly greater due to their more complex structure and composition. At the same time, prerequisites are created for realizing the advantages of the overall reliability model - taking into account the complex interrelationships both between these factors and processes, as well as between the individual elements of the structure of the complex technical object.

Since the task of developing such a complete reliability model of a complex technical object is of a volume far beyond the scope of the report, only one fragment of this model – covering a specific assembly system – x-axis translation is considered in the present work. This makes it possible, after the construction of similar models of the other component systems, to combine them into one complete model.
