В существующей ситуации высокой непредсказуемости и динамичности рыночного окружения эффективная организация производственного и сбытового процесса становится ключевым фактором успешного функционирования и поддержания долгосрочной конкурентоспособности угольных предприятий на внутреннем и международном рынках. Основой повышения эффективности деятельности угольных компаний может стать применение современного экономико-математического инструментария оптимизации планирования производственной и сбытовой деятельности. Основной целью исследования является совершенствование методического инструментария планирования производственно-сбытовой деятельности угольных предприятий для повышения ее эффективности. В работе представлены результаты исследования особенностей производственно-сбытовой деятельности российских угольных предприятий в современных рыночных условиях: выявлены внешние факторы и внутренние ограничения, оказывающие существенное влияние на эффективность их деятельности, проанализированы существующие методы планирования производственно-сбытовой деятельности, а также обозначены возможные пути повышения эффективности. В магистерской диссертации разработан методический поход к оптимизации планирования производственно-сбытовой деятельности угольных предприятий с применением экономико-математических методов и методов оптимизации плановых решений. / In the current situation of high unpredictability and dynamism of the market environment, the effective organization of the production and marketing process becomes a key factor in the successful functioning and maintenance of long-term competitiveness of coal companies in the domestic and international markets. The basis for improving the efficiency of coal companies can be the use of modern economic and mathematical tools for optimizing the planning of production and marketing activities. The main purpose of the study is to improve the methodical tools for planning the production and marketing activities of coal companies in order to increase its efficiency. The paper presents the results of a study of the features of the production and marketing activities of Russian coal companies in modern market conditions: external factors and internal constraints that have a significant impact on the efficiency of their activities are identified, existing methods of planning production and marketing activities are analyzed, and possible ways to improve efficiency are identified. In the master's thesis, a methodical approach to optimizing the planning of production and marketing activities of coal companies was developed using economic and mathematical methods and methods for optimizing planned decisions.

This diploma thesis deals with behavioural problems of pupils in a school setting, particularly with aggression and bullying, as well as the possibility of their prevention. It consists of a theoretical part, a practical part, and appendices. The theoretical part treats behavioural problems in pupils, presenting the separate disorders in all their possible forms, accounting for both internal and external factors triggering them, explaining their causes and the conditions under which they occur, and, finally, surveys the possibility of their prevention and treatment. The practical part uses a questionnaire designed by the author of the thesis and discussions conducted in schools to identify the most common types of behavioural disorders. The results of the research are presented in charts and graphs and are complemented by data obtained in the discussions. This part is concluded with a thorough analysis of the data. The appendices contain real-life examples of behavioural problems encountered by teachers, the minimum prevention programme implemented by the basic school in Jistebnice and its evaluation for the school year of 2008/2009, the crisis management scheme of the same school, and additional materials relating to the topic.
