Modeling the dynamics of production and distribution systems

Abstract

The article studies the dynamics of production and distribution systems under a high degree of demand and supply instability, characteristic of current market conditions. The paper develops a «flow tank» technological process for a logistical distribution module. This principle, first proposed by J. Forrester, assumes the alternation of blocks characterizing volume indicators with indicators of flow intensities. The modelling, analysis and decision-making methods based on several logistic modules of production and distribution systems are considered. The proposed methods aim to increase the operational efficiency of flows and processes in various logistics modules. The proposed technological algorithms and equations for managing product and information flows demonstrate a fruitful way of analyzing and improving decision-making in production and product distribution systems. The paper also proposes practical algorithms for modelling demand and production conditions for the modules under consideration. The simulation and analytical models of the proposed modules can serve as the basis for creating information systems for efficient analysis and planning of operating processes in supply chains.
