Actual directions of digitalization of pipeline systems and methods of analysis of their properties as cyber-physical objects

Abstract

The characteristics of the goals and objectives of digitalization of pipeline systems (PS) are given, during which they acquire new properties of cyber-physical objects. A structure of tasks of general importance for PS of various types and purposes (heat, water, oil, gas supply, etc.) is proposed. The characteristic of probabilistic state models is given. On this basis, a system of indicators for analyzing the controllability, identifiability and observability of PS is proposed, and their relationship is disclosed. For the first time, analytical dependences of the parametric identifiability of PS on the composition of measurements have been obtained.
