چکیده
The article describes numerical method of physical gas flow parameters recovery at gas trunkline and distribution pipeline networks. The information about full-scale measurements of time dependences of gas flow parameters at defined points inside pipeline networks and at its boundaries is the base for recovery implementation. Numerical simulation is carried out by defining and solving an optimisation problem.
