The results of using an automated system for the production of metallurgical products (AS PMP) to solve problems of analysis and optimization of in-plant logistics processes are presented. The logistics processes under study are formalized by a model of resource transformation processes implemented in the modeling subsystem. A feature of these processes is the presence of bottlenecks associated with the occurrence of conflicts on shared resources and facilities. A hybrid method for analyzing and eliminating bottlenecks is proposed, implemented in an automated system for the production of metallurgical products in order to support the optimization of the processes under study. As a result of applying the hybrid method to the problem of optimizing the logistics processes of an oxygen converter shop, practical recommendations were obtained on the formation of intervals for supplying melts to the shop's converters in order to prevent downtime of continuous casting machines.
