Abstract
The report describes a flexible software package for modeling the production planning process to solve the problem of optimizing the preparation of calendar schedules of multiassortment continuous-discrete enterprises characterized by a large range of products, many types and configurations of equipment. Since the number of variants of production schedules increases exponentially with increasing dimensionality of the task, it is relevant to develop a specialized complex of effective optimal planning, insisting on the characteristics of various multi-assortment productions. The development is based on the use of methods of the theory of schedules, optimization and evolutionary calculations, tools for object-oriented development of complex software systems and databases. The proposed software package has various intelligent user interfaces supplemented by databases of products, equipment and technological regulations, a library of objective functions and mathematical optimization methods, a module for expert system configuration, as well as an interactive visualization system of the obtained production plans in the form of a Gantt chart and a tree of optimization problem solutions. Testing of the software package on real industrial data of polymer and metallurgical industries confirmed the effectiveness of solving planning problems using the proposed methods and algorithms. The implementation and use of the proposed software package makes it possible to ensure efficient loading of the enterprise's equipment, reduce the cost of production and simplify the process of making managerial decisions during production planning.
