PLANNING OF TRANSPORTATION OF RHEOLOGICAL COMPLEX OILS FROM VARIOUS FIELDS THROUGH AN EXTENSIVE PIPELINE SYSTEM, TAKING INTO ACCOUNT ENSURING THE SPECIFIED QUALITY OF THE DELIVERED OIL

The article discusses the problem of operating an oil pipeline system in the presence of a significant number of suppliers of rheologically complex oils with different sulfur content and a large number of oil consumers with different requirements for oil quality in terms of sulfur and other parameters. The problem of determining optimal cargo flows in such a system is discussed. A method is proposed for determining optimal cargo flows in a branched oil pipeline system, providing a global optimum in terms of minimizing energy costs for pumping. The article provides an algorithm for implementing the method using a conditional example.
