Engineering networks simulation and assessment of the mathematical model accuracy

The article shows the way to implement a quasilinear mathematical model of flow distribution in pipeline engineering networks that is effective wide range changes multidimensional random vector loads at network nodes and provides reliable determination parameters probability functions flows active passive elements. proposed consists determining matrix generalized parameters-the load coefficients along branches circuit, calculated point corresponding expectation node loads. Based on obtained model, convergence results with simulation proved using numerical experiment an electronic computer. effectiveness developed algorithms set programs for computer shown - value criterion reduced costs parametric optimization can be by 5-7% compared methods used practice. possibility obtaining design stage equivalent hydraulic characteristics form data experimental measurements pressures real complex proved.
