Description
Summary:Within the framework of the theory of optimal control, problems on the localization of the points of oil leakage from a transport pipeline system and on the determination of the rate of these leakages were investigated. Analytical formulas for the gradient of the functional that determines the deviation of oil flow conditions at the given points of a pipeline section from the calculated ones were obtained. These formulas allow one to use numerical methods of first-order optimization for solving the problem posed. Some results of numerical experiments are given.
