1. PreorderOverall construction site plan is the important component part of construction organization design, the freight volume that reduces inside, construction site to greatest extent is one of important criteria of design and construction master plan, drafts material scientifically and rationally, gives goods, the position in warehouse that semi-manufacture are deposited or stockyard is the key of reduction freight volume.The present invention is applicable in the situation of building many buildingss of construction on the domain, the position of these buildingss is all definite in the planning stage, these positions just become the supply centre (hereinafter to be referred as " supply centre ") of construction stage building materials, the position in stored central warehouse of supply centre material requested or stockyard (hereinafter to be referred as storehouse, field) then is to determine when the design and construction master plan, storehouse, position difference then its transportation total amount to material that carry each supply centre are also different, use technological means of the present invention and can ask and obtain the minimum storehouse of transportation total amount, position, field.Existing technology does not also have what advanced person'"'"'s method to asking the optimum position of seeking above-mentioned central warehouse, and the present invention makes a kind of computing machine firmware (firmware belongs to hardware) coupled computer drafting system to ask the optimum position of obtaining central warehouse.On overall construction site plan, draw each supply centre, on this planimetric map, draw rectangular coordinate, make easy that the position of coordinate helps calculating as far as possible, as to make the distance of coordinate axis and some supply centre be zero etc. that each supply centre is symbol and coordinate figure on coordinate:

  • P 1(x 1y 1);

    P 2(x 2y 2) ... P φ

    (x φ

    y φ

    ), storehouse, symbol and the coordinate of field on coordinate of transportation total amount minimum are S (xy). Feature of the present invention1. firmware of the present invention has following functional expression (1), (2), and they rely on computer plotting system formation curve image, and this firmware is positioned in the corresponding site of computer plotting system.f 1(x,

    y)=

    0 (2) In the above-listed functional expression, x, y are variable, and other are known number, Q 1, Q 2... Q φ

    Be the quantity of material of each supply centre by storehouse, place supply, φ

    is the supply centre sum.
