MODEL OF OPTIMIZATION OF FUNCTIONING OF MODERN POLYGRAPHIC AND PUBLISHING COMPLEXES

Abstract

Analysis of known methods and modern equipment for printing and publishing (sheet rotary machines, roll machines, flat-printing and platen machines for flat impression block, relief, intaglio and digital printing) is conducted in this article. In a result of the analysis article authors have to make a conclusion, that most prospective equipment for automated printing and publishing complexes are: high-performance sheet and roll machines, in that number crucible, flatbed and rotary three-cylinder machines and also single-layer and multi-layer sectional machines, digital laser and inkjet machines. Authors propose a mathematical model of an automated optimization system of functioning of modern printing and publishing companies. In the model are used databases with information about orders (quantity, volumes, content, terms of orders fulfillment, admissible prime value and characteristics of quality of finished products), production capacities of printing and publishing enterprises of the region (destination, quantity and productivity of equipment, its technological capabilities, loading with other orders, service life), as well as additional data about value of transportation and storage of ready products, the possibility and feasibility of transferring orders to other enterprises and more. The elaborated model can be used as a basis for creation of a computer program for automated synthesis and analysis of functioning optimization of modern printing and publishing companies in the region to improve their efficiency, as well as for help customers of printing products in selection of optimal variants of orders fulfillment. The modeling results will allow to rationalize the utilization of enterprises capacity, to reduce the value of finished products, to ensure their proper quality, to avoid of disruptions during of peak periods of enterprises loading, to reduce the value of repair and maintenance of the complex equipment.
