Problems solved by technology

The arrangement for returning to the warehouse in the traditional depot is determined by the line adjustment and inspection before each vehicle returns to the warehouse according to the operation requirements. Due to the lack of predictability due to the lack of overall planning, the operation requirements of the vehicles returning to the warehouse at a later time may not be met. Cause delays in operations or unnecessary shunting a

Embodiment 1

[0151] The layout diagram of a subway depot line is as follows: Figure 4As shown, the vehicle enters the depot from the left, and the main parking areas at night are the operation warehouse (4 lanes to 16 lanes) and the maintenance warehouse (17 lanes to 19 lanes), of which the A lane has a trench and the B lane has no Trench, the 17th to 19th lanes are equipped with trenches and protective nets, vehicles can enter and leave the warehouse from left or right, and the right-hand entrance and exit need to go through the walking line.

[0152] Verify the effectiveness of the algorithm, and establish a simulation platform for the arrangement of the return and depot lanes of the subway depot. Set the parameters of the algorithm according to experience, set the population size Z to be 40, and the hybridization probability p c is 0.8, the mutation probability p m is 0.1, set the maximum evolution algebra to 20, and the fitness function variable a to 0.5. First of all, the vehicle ...

Abstract

The invention discloses a return track way arrangement method for a subway vehicle segment. The method comprises following steps: firstly, collecting the required to-be-returned vehicle information and the required to-be-returned track way information and establishing parameter sets of practical problems; secondly, selecting a proper encoding mode to configure the chromosomes and making population initialization rules so as to generate Z chromosomes to form an initial population P; then, according to the practical problems, determining an optimal target function and a constraint; and finally, determining a selection rule of individuals and a specific operation mode of hybridization and variation, calculating an adaptive value of each individual and storing the individual with the biggest adaptive value according to a fitness function and repeating the operation until reaching to a maximum evolution algebra. By use of the return track way arrangement method, train tasks can be properly selected or rejected and an optimal track way arrangement scheme can be found under a resource constraint condition; a decision support is provided for subsequent daily inspection and shunting operation; and working efficiency of the vehicle segment is greatly increased.

Description

technical field [0001] The invention belongs to the technical field of rail transit, in particular to a method for arranging a return track of a subway car depot. Background technique [0002] As the main station section of subway production and transportation, the subway depot is mainly responsible for the parking, inspection, maintenance, operation and repair of vehicles. When the subway vehicles need to stop at the depot after finishing the operation plan for the day, waiting for maintenance work or leaving the train tomorrow, it is of great significance to scientifically arrange the parking lanes for returning vehicles to the depot to improve the production efficiency of the depot. The arrangement for returning to the warehouse in the traditional depot is decided by the line adjustment and inspection according to the operation requirements before each vehicle returns to the warehouse. Because there is no overall arrangement and lack of predictability, the operation requi...
