DEVELOPMENT OF A SYSTEM OF SHEDULING AND NETWORK PLANNING OF PROJECTS OF COAL INDUSTRY ENTERPRISES: THE EXAMPLE OF «ATOMENERGOPROEKT» JSC; [Разработка системы календарно-сетевого планирования проектов предприятий угольной промышленности: опыт АО «Атомэнергопроект»]

Against the background of the development of information technology and the Internet of Things, traditional planning methods often ignore production laws and the knowledge hidden in production data. In today's fiercely competitive global market, coal industry enterprises are faced with more stringent requirements to increase production efficiency, reduce resource consumption and reduce production costs.The core of economic sustainability of coal industry enterprises becomes the systems of scheduling and network planning. In this regard, the need for economic development is impossible without the use of information technology. Thus, the experience of using the integrated design management system of «Atomenergoproekt» JSC gives an opportunity to significantly improve the efficiency of coal industry enterprises, namely, to significantly increase the level of decision-making and ensure the effective functioning of the technological process. Efficiency of optimization and efficiency of decision-making are two contradictory goals, which are necessary for effective operation of industrial enterprises in general. In this regard, the authors have proposed and described a methodology for calendar-network planning of projects of coal industry enterprises, which includes the results of mathematical evaluation of the criteria and constraints. The authors believe that the satisfaction of these criteria and constraints will improve the efficiency of coal industry enterprises under international sanctions. © 2023 Ugol' Journal Edition, LLC.
