By taking the complicated tree gas main transmission pipe network system as the research target, based on the gas pipe transportation theory and optimizing design theory after surveying design,the optimizing design problem of the whole gas transmission pipe network is divided into three sub-problems, i. e. layout optimization, parameter optimization and optimum program seeking, by use of a multistage optimization tactic. Through setting up mathematical models for each member of the subproblems and solving by effectively seeking optimum method, the best program of the whole pipe network system and its investment cost analysis are achieved finally. An optimizing design software of the complicated treed gas main transmission pipe network system has been developed, and through calculating a case with the software, it is proved that this design theory is right and the design method has a certain of reference value for the other researches on optimization.
