[0045] A method for designing a local material transportation plan for railway engineering construction considering multiple factors provided by the first embodiment of the present invention will be described in detail below in conjunction with Figure 1 this.

[0046] As Figure 1 shown, in step S1, the work points, material source points, and information on the main roads passing through of the railway engineering project are obtained, and a project information database is established.

[0047] The above steps specifically include:

[0048] Step S1 specifically includes:

[0049] S11, obtaining information on all construction work points of the railway engineering project;

[0050] S12, obtaining information on material source points within the scope of the railway engineering project area;

[0052] S14, making an access line from the material source point or work point to the main road, and determining the main road mileage corresponding to the material source point or work point according to the intersection of the access line and the main road.

[0053] As Figure 2 shown, the black line in the figure is the railway line, the black solid dots are the construction work points of the railway, the red line is the main road passing through the area, the red solid dots are the material source points, the blue line is the access line from the material source point or work point to the main road, and the intersection of the access line and the main road can obtain the main road mileage corresponding to the material source point or work point.

[0054] Establishing the project information database specifically includes:

[0055] Work point information database: including the main road mileage corresponding to the work point and the length of the access line from the work point to the main road;

[0056] Material source point information database: including the main road mileage corresponding to the material source point, the length of the access line from the material source point to the main road, and the ex-factory price of the material;

[0057] Unit freight of materials (yuan / t.km).

[0058] AsFigure 1 As shown in Figure 1 , in step S2, based on the project information database, various factors including the ex-factory price of materials, material freight, and transportation distance are comprehensively considered. With the goal of minimizing the material transportation cost of a single work point, the most economical material source point for each required material category at the work point is obtained, and finally the local material transportation plan for railway engineering construction is obtained.

[0059] The core of the embodiment of the present invention is to establish an economic calculation model under complex road networks and different material source points. The general principle is to optimize the economy of material allocation to reasonably establish the calculation model.

[0060] The above steps specifically include:

[0061] Each railway project has several work points and has several categories of material requirements. Each category of material has several material source points.

[0062] S21, select a certain material category. The corresponding material category includes n material source points. With the goal of minimizing the material transportation cost of a single work point, determine the most economical material source point for a certain work point under the corresponding material category. The calculation method is as follows, and the calculation formula is as follows:

[0063] Q = min(L1*K + C1, L2*K + C2,..., Ln*K + Cn)

[0064] Where:

[0065] Q is the material transportation cost of a certain work point, and the unit is yuan;

[0066] Ln is the transportation distance from a certain work point to the nth material source point, and the unit is km; Ln = (the mileage of the main road corresponding to the material source point - the mileage of the main road corresponding to the work point) + the length of the access line from the work point to the main road + the length of the access line from the material source point to the main road;

[0069] Thus, a one-to-one correspondence between the work point - the most economical material source point under the corresponding material category is established.

[0070] S22, traverse each required material category, and then the most economical material source point for each work point under each material category can be determined. By obtaining the most economical material source point for each work point under each required material category, the local material transportation plan for railway engineering construction can be obtained.
