Optimal Planning Software Package for Use in the Control System of Flexible Extrusion Production of Polymer Materials

Abstract

A software package has been developed that allows solving the problem of optimal planning of the distribution of a package of orders over time for execution on extrusion lines of various configurations in conditions of limited resources and taking into account deliveries. The complex allows you to automate the planning task for geographically distributed industrial enterprises and corporations that manufacture products on production lines that are reconfigured to a different assortment and face the problem of efficient use of their production resources. The production director interface allows the user to select the planning period, the target function (time or cost of production), orders and production lines. The database administrator interface supports the information support of the software package and allows you to import data for planning. The knowledge engineer interface allows you to configure the system for various hardware configurations and the rules for its reconfiguration. The basis of the software package is a customizable library of optimization methods, which allows you to choose an optimization method depending on the dimension of the task and the characteristics of the planning object. After building the production plan, the software package presents the planning result to the user, presented in the form of a Gantt chart and a tree of solutions to the optimization problem. Testing of the developed system was carried out on the production data provided by companies producing polymer films in Russia and Germany, and confirmed its operability and efficiency of application due to a reduction in the expected time and cost of production, as well as by reducing the time for making managerial decisions in the production planning process.
