Conceptual model of hierarchical organization of engineering network systems

Abstract

Due to the commonality of a number of characteristic properties and features, which, in particular, are the
functional purpose, topological structure, flow distribution models, as well as management tasks, methods and algorithms, agricultural water supply systems, as well as irrigation systems, can be attributed to the class of hierarchically organized engineering
network systems (ENS). Based on the analysis of existing and designed ENS, it can be concluded that such objects can be decomposed into separate local networks (LN) of different hierarchy levels, which are interdependent and interact with each other
in the process of functioning. At the same time, real ENS at the highest level of the hierarchy as LN contain backbone networks
(BN), to which LNs of lower hierarchy levels are connected - distribution networks (DN). The LNs of the lowest hierarchy level -
networks of consumers of the target product (NCTP) are connected to the LN of the penultimate hierarchy level. They are directly connected to the consumers of the target product (CTP), which ultimately consume the target product (TP), water, from the
considered hierarchically organized ENS [1, 2]. The functional purpose of the BN is the consumption of TP from sources external to the ENS, its transportation and redistribution between the DNs connected to the considered BN. The functional purpose of
the DN is the consumption of TP from the BN to which this DN is connected, its transportation and redistribution between the
NCTPs connected to this DN. The functional purpose of the NCTP is the consumption of TP from the DN to which this NCTP is
connected, its transportation and redistribution between the CTPs connected to this NCTP. Due to stochastic changes in the
modes of TP consumption by individual NCTP s, the implementation of the operational management processes of the ENS is
necessary to create acceptable conditions for their functioning.
