Study On Drainage System Lay-out Plan Optimization

This text discussed the city drain pipe net programming the excellent turning the research meaning of the design first with the domestic and international research present condition, combining to introduce the city drain the concept of the engineering and its the predicament that face, explained to proceed the excellent turning the necessity of the design to the drain pipe net programming.Commence from the network characteristic analysis of the drain pipe net immediately after, join together the principle of the diagram theory with the method, become drain pipe net to a the power of arc for matching geography inclination trend having direction diagram, and giving each arc plusing with piping developments expenses function for power function all according to the characteristics of the city drain pipe net, the decision diagram model that established the catchment our country the programming on these grounds.On the above analytic foundation, put forward to the drain pipe net the diagram model proceeds the excellent turning the calculating target the function and controls the term, constituting excellent turn the square distance in立 in calculating set, and choose the F —W calculate way is to begs to solve the calculate way the other party the distance set proceed to beg the solution, formation drain pipe the net programming is excellent to turn a the whole set of the method of solution of the design, finally, with dirty water in area in high and new west in city system programming for an usefulness for, verifying drain pipe net system programing excellently turning designing method.Principle of this text at diagram theory with method with the work that the actual work that city drain pipe net program join together ascends did the beneficial trial, the solution method calculation that put forward convenience, economic performance obvious, at the same time, use MATLAB calculator language plait write drain pipe net programming excellent turn the calculator procedure of the design, make a programming for putting forward method have the better function.
