Abstract

The newest stage of economic development, which experts call the "economy of interactions", is associated with the spread of network structures and organizations, the effective operation of which requires a new quality of interaction and management. Multi-channel network supply chains are functionally and organizationally more advanced, meet the requirements of the modern market as much as possible, and allow you to form an adequate product offer in the network of relevant supply and sales channels. However, the more complex the structure of the supply chain, the higher the degree of its internal connectivity and interdependence, and the more it is exposed to uncontrollable events and, accordingly, failures or rejections. The ramifications and complexity of agricultural products supply chain increase attention to their reliability and the need to develop new methods and models for maintaining and ensuring the necessary level of reliability of the supply chain of agricultural products, especially in today's difficult geopolitical conditions. The article discusses approaches to the formation of a multi-level model of structural reliability of the supply chain. It proposes a scheme for its assessment, which quantitatively describes the state of stability of the supply chain in the event of the spread of failures and rejections. An outsourcing planning model has been studied, in which the task of forming a supply chain food turns into the task of selecting channels with the lowest costs, provided that the requirements for reliability are met. The calculations show that multi-channel (network) supply chains for agricultural products with backup channels provide increased reliability, stability, and recoverability. A series-parallel model of structural reliability has been proposed, which ensures the flexibility of the supply chain with given reliability due to the possibility of regulating the volume of supplies by channels.
