Automatic fit of parameters under identification of mathematical models to the real failures

摘要

The method for automatic fit of integral parameters of engineering systems was proposed. These parameters ensure adequacy of physical process simulation in these systems under failure initiation, process, and localization. Description is executed by the example of fitting the pipe wall roughness integral values ensuring adequacy of computation fluid dynamic simulator operation and the real pipeline network operating in nominal, transient, and failure modes. Automatic fit is performed as a result of minimax mathematical optimization problem statement and solution.
