5. The BIM-based building pipeline placement optimization system of claim 1, wherein the pipeline calculation module is for companies that match the unified procurement of second pipelines and intercepted pipelines; the device comprises a data acquisition unit and a data and data calculation unit; the data acquisition unit is used for acquiring the information of manufacturers corresponding to the pipeline models in real time; the manufacturer information comprises the position of the manufacturer, the price and the sales volume corresponding to the pipeline model; the data acquisition unit sends the manufacturer information acquired in real time to the data calculation unit; the data calculation unit is used for calculating a matching value of a manufacturer; the specific calculation steps are as follows:
the method comprises the following steps: set the manufacturer corresponding to the pipeline as CkGi(ii) a k is 1, 2, … …, n; the price and the sales volume corresponding to the model of the pipeline produced by the manufacturer are respectively recorded as MCkGi、XCkGi；
Step two: obtaining the distance difference SCk according to the position of the building using the pipeline and the position of the manufacturerGi；
Step three: using formulas
Obtaining the matching value PCk of a manufacturerGi(ii) a Wherein g1, g2 and g3 are all preset fixed values of proportionality coefficients, and MY is the preset price of the pipeline;
step four: marking the manufacturer with the maximum matching value as a company for uniformly purchasing the second pipeline and the intercepted pipeline;
step five: and the pipeline calculation module stores the company sending value database for the unified purchase of the second pipeline and the intercepted pipeline in a database, and marks the company address and the contact telephone for the unified purchase on the outer surface of the pipeline corresponding to the building pipeline model.
