The intensity of the flow of the logistics chain

Abstract

Assessing the intensity of logistics flows is one of the most important functions of consumption management in socio-economic systems. Today, there is a need for rapid and flexible response of production, trade and transport systems to changing consumer priorities. Logistics takes over the solution of this complex problem. The intensity of the logistics process includes a wide range of issues from resource extraction, resource processing, storage, distribution and delivery of the finished product to the consumer. The paper considers the issues of modeling the intensity of logistics chain flows. A block diagram of the logistics process is constructed. The concept of logistics flow is given and its mathematical model is constructed. The mathematical model of the logistics flow is based on the correspondence of the logistics and electrical circuits. The parameters of the logistics flow model are determined. The relations between the parameters of the electrical and logistics chains are found. Transients in logistics chains are considered. Mathematical models have been developed to study the intensity of logistics flows using the Mathcad program. The analysis is carried out and conclusions are made. The analysis has shown that under any models of the economic system, a halt in development leads to a sharp decrease in the intensity of the logistics flow. In the conditions of a developed system, the market economy has an advantage in the intensity of the logistics flow compared to the planned economy, but the fluctuating process leads to constant economic crises, which disrupts the sustainable development of the system. The planned model is the most resistant to economic crises, this is confirmed by the development of China in the modern conditions of the pandemic.
