The model of water supply network is a set of large databases, the complexprofessional model, the advanced hardware and software systems for the integrated system.Each water supply network model must calibrated model parameters before put into use,making it enable to accurate simulate the operating conditions, and a series of applicationanalysis. The content of this study include the following aspects:1、Compared with the foreign block water supply network which has the main pipewith little pipe circle, in our country it is a general mode of spider web-like structuralarrangement, which makes more complex about water supply network model established. Itis difficult to simulate the operational status of the water supply network. About thissituation, this paper proposed a corresponding method to the establishment of the overallwater supply network model database, data collected and managed; proposed our country’spipe network modeling method, partition modeling, partition calibrated, integrated into anetwork; and node flow distribution method about water supply network model.2、Using the sum of squares about the difference between the measured value andsimulation value about water supply pipe network node pressure and pipe flow as theobjective function. Using DFP variable metric improved genetic algorithm to solve it, byadjusting the pipeline friction coefficient of C value, make the model meets the precision.3、To analysis the uncertainty in the pipe network model, and proposed the method ofprocessing steps and the difference between manually check and automatically check in thepipe network model checking. This paper redefined the pipe friction coefficient C value, themeaning of the new definition of pipe friction coefficient C value is that it not onlyrepresents the pipe wall roughness, but also on behalf of the pipeline corrosion or someother unknown reason to make the water capacity of the pipeline was investigated. And thispaper also researched the simplified of network model.4、Take water supply pipe network model of BC in W city marketing as an exampleresearch object, calibrate the pipeline flow and pipe friction coefficient, mainly adjusting the pipe friction coefficient C value.Calibrated results show that the network model can meet the accuracy requirement ofthe model application and certify that the above network model of the processing methodhas a certain feasibility.
