Method of Analysis of Production and Logistics Systems of Discrete Production Based on Product-Process-Resource Model, External Module for Manufacturing Control Logic and Simulation of Work Execution

Abstract

The defining features of digital twins of the production and logistics system of a multi-nomenclature machine-building enterprise are considered. It is shown that during the life cycle of the production and logistics system of a machine-building enterprise, it is subject to changes that are caused by changes in the nomenclature, output program, production volumes, distribution of the order flow over time, and other factors. This leads to the need to reengineer not only technological processes and resources, but also the enterprise management system. To support the adoption of organizational and technological decisions and the choice of an enterprise management system, simulation systems, systems for developing production schedules are used. The article offers a structural model and the principles of interaction of its elements that allow for the design and analysis of the production and logistics system of a machine-building enterprise with a discrete multi-product type of production. Features of systems for building production schedules and systems for simulating production processes are considered. As an integration basis for interaction, it is proposed to use the unified DPML language for describing production and logistics systems in the form of “product-process-resource”.
