The dissertation is devoted to the solution of the actual problem - finding a new approach to the polypropylene fiber filter elements (PFFE) production management. The dissertation analytically and practically substantiates the feasibility of creating an information system that will manage such important PFFE production processes in the enterprise, as the order and the PFFE direct formation technological process.
The purpose of which is to reduce the time for the PFFE design process, optimize the number of layers choice by their structure and volume to achieve certain PFFE properties and product quality control, as well as the introduction of information technology production information system.
For an appropriate information system creation with faster order processing and production tasks formation, and with the technological processes support, a number of components are needed - technical, informational and universal mathematical apparatus, represented by a set of mathematical methods and models. Such a mathematical apparatus can be used to solve problems of modeling and improving the control process
As a result of the researchers works analysis and of the Ukrainian manufacturers practical experience it is possible to draw a conclusion that the question of elements from polypropylene manufacturing is quite promising and widespread. But as for the creation of elements from porous polypropylene production by pneumoextrusion information technology, to date there are no similar studies in this area.
The analysis of the enterprises activity on PFFE manufacturing is carried out, the technological process at the enterprises is researched, and technological process parameters dependence from the filtering element (FЕ) scope of application is revealed.
The main parameters on which the desired type element (or filter element, or drainage) production depends. The main ones are the melting temperature in the last
heating zone of the extruder, the dosing pump revolutions and, accordingly, the mass of the polymer melt revolutions, the air pressure supplied to the forming head and the air temperature supplied to the forming head.
Developed classification and technological production schemes are intended for further flexible improvement and system integration with an industrial information complex of industries any enterprise. The logical-structural approach of the basic directions definition in the information technology development for the chemical industry enterprise is applied.
The information technology as algorithms and methods and information system architecture is developed. It consists of two separate main structural blocks: software module for the mathematical apparatus and PFFE technological suitability of quality control functions implementation, and order management software module. These modules are united by an interface.
The mathematical apparatus modules are used to implement best fiber thickness selection and to pick production process technological parameters depending on the scope of application, which has great practical significance in the final product manufacturing process.
The developed information system allows to purposefully manage the quality of the final product during the technological process of its production. The system main parts can be considered separately. In this case, it is possible to make changes and expand functionality without changing the entire system. Each of the software modules is divided into two parts - the server part, which deals with processing, storage and exchange of information and the client part, which is a mobile application that collects and provides information in a user-friendly (operator) form. The greatest importance of research lies in the automated selection of production technological parameters. The developed information system will provide prompt, substantiated information for the operator to make the right technological decisions.
The results of the system application showed that the effectiveness increased with the relevant information technology implementation by an average of 12%, which means that
the profit of the enterprise with the information system implementation increased by an average of 12% per year.
