Effective logistics management in vertically integrated oil companies (VIOC) is an important factor of business success. Losses caused by irrational logistics management may reach hundreds of millions of rubles a year. Therefore, mathematical simulation of VIOC logistics and methods of optimization of high dimensionality systems represent a relevant problem.The author presents a logistics model for VIOCs and their oil products. The model is based on methods applicable to linear programming problems, algorithms of reduction and restoration of high dimensionality matrixes, and the software developed by ILOG Ltd., a leading developer of applied software components.The software package, developed by the author, solve the problem through the optimization of purchases, production, storage, flow and sales of VIOC oil products, in respect of dozens and even hundreds of small companies of the group. The software package takes account of a big variety of types of contracts between companies, delivery service providers, and storage facilities.This solution may be used to generate a wide range of reports both for VIOC as a whole, and for each VIOC constituent company.The software package has been successfully used for 5 years in respect of logistics, operational and strategic planning of purchases, production, storage, flow and sales of oil products, as well as generation and development of an optimal distribution network.The software was integrated into the corporate resource consumption planning system (ERP System). The assessment of the mathematical simulation is also provided and analyzed in the article.<br>Предложен пакет прикладных программ для решения задач линейного программирования высокой размерности. В основе пакета лежат алгоритмы редуцирования и восстановления матриц высокой размерности и программное обеспечение ILOG.Разработана и программно реализована модель логистики нефтепродуктов для вертикально-интегрированных нефтяных компаний. Приведены оценки результатов моделирования.
