Embodiment 1

[0098] like figure 1 As shown, a fast and intelligent optimization method for the operation and maintenance scheme of the EMU in this embodiment includes the following steps:

[0099] Step 1: basic data integration and planning parameter setting;

[0100] Step 2: According to the conditions of step 1, the preliminary EMU operation and maintenance plan is obtained through the fast intelligent optimization algorithm;

[0101] Step 3: Carry out manual fine-tuning on the basis of the preliminary EMU operation and maintenance plan;

[0102] Step 4: Carry out constraint verification on the EMU operation and maintenance plan after manual fine-tuning and give a prompt, and return to step 3 if the verification fails.

[0103] Among them, the basic data in step 1 include:

[0104] 1) EMU information: covering vehicle type, capacity, head direction, current accumulated mileage and online time information. This data requires data synchronization across the entire road to ensure data co...

Embodiment 2

[0171] like figure 2 As shown, a fast intelligent optimization method for the operation and maintenance scheme of the EMU in this embodiment is basically the same as that in Embodiment 1, the difference is that:

[0172] Step 4: Carry out constraint verification on the EMU operation and maintenance plan after manual fine-tuning and give a prompt, and return to step 2 if the verification fails.

Description

technical field [0001] The invention relates to technologies related to automatic scheduling of motor train maintenance and use, in particular to a fast and intelligent optimization method and system for the operation and maintenance scheme of train trains. Background technique [0002] Our country has gradually built a high-speed railway system of "four vertical and four horizontal". However, the operation and maintenance rules of EMUs are complex, involving constraints in multiple dimensions such as roads, vehicle types, capacity, maintenance items, and maintenance cycles, and the operation and maintenance programs of EMUs interact and restrict each other, making the preparation of EMUs difficult. The use of maintenance schemes becomes a large-scale combinatorial optimization problem. At present, there is no mature software product to realize the automatic optimization solution of this scheme, and to assist the operation, maintenance and scheduling of EMUs. In practice, ...
