To Optimum Combined piping Network by Nodal Recurrence Algorithm

According to the drawings and matrix algorithm of the combined piping network system the paper puts forward node recurrence optimum algorithm. It takes the nodal as the study object to optimize the combined piping network system. The algorithm can solve the calculation problem connection of pipe section on the upper and down reaches of the piping network at convergence place and to overcome the difficulty undetermined control points to reach the optimum target of the minimum cost, and it can directly take the nodal elevation as the restrained condition to fully consider to use the original piping or solve the intersect problem of the underground piping. And it is verifies by examples.
