IMULATION OF LOGISTICS PROCESSES IN PLANNED INVESTMENT PROJECTS
The paper considers and describes models of system dynamics. The main goal of this work is to demonstrate the differences between linear modeling and system - dynamic modeling of investment projects. When planning investment projects, the system impact of logistics processes (such as procurement, storage, sales, etc.) in the form of time delays and feedback loops - elements used in system dynamics - is often not taken into account. In the process of modeling, the authors present a set of these events. The relevance of the work is explained by the existing problems in the supply chains today associated with the COVID - 19 pandemic, which can have a significant impact on the logistics processes in companies. The Ventana Systems Vensim PLE program was used as a data processing tool for building the model. The model is available as an .mdl file called "System - dynamic model of FMCG logistics processes" at data.mendeley.com.
