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 and time-consuming, so consider optimizing the arrangement of the return lanes to ensure the reasonable and efficient operation of the depot to the greatest extent
[0003] At present, there is no research on the algorithm for the arrangement of depot return lanes, but the research on the use of locomotive depot maintenance areas and passenger station lanes has certain reference significance for the algorithm design of depot return lanes

Embodiment 1

[0151] A schematic diagram of the line layout of a subway depot Figure 4 As shown, the vehicle enters the depot from the left, and the main parking areas at night are the service warehouse (4 strands to 16 strands) and the maintenance warehouse (17 strands to 19 strands), of which the A-share road has a trench and the B-share road has no Trenches, 17 to 19 strands are equipped with trenches and protective nets. Vehicles can enter and exit the warehouse from the left or right, and the right direction must go through the running line.

[0152] To verify the effectiveness of the algorithm, establish a simulation platform for the arrangement of the subway depot back to the warehouse. Set the algorithm parameters based on experience, set the population size Z to 40, and the hybridization probability p c Is 0.8, mutation probability p m Set the maximum evolution algebra to 20 and the fitness function variable a to 0.5. First, the vehicle information and the status of the stock lane wh...

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 the stock lanes of subway depots. Background technique [0002] As the main station of subway production and transportation, the subway depot is mainly responsible for the parking, inspection, maintenance, operation and repair of vehicles. When the subway vehicle ends the day's operation plan, it needs to be parked in the depot for maintenance work or tomorrow. It is of great significance to scientifically arrange the parking lane for returning vehicles to the depot to improve the production efficiency of the depot. The arrangement of the traditional depot returning to the warehouse is determined by the dispatch and inspection based on the operation requirements of each vehicle before returning to the warehouse. Due to the lack of overall planning and lack of foresight, the operation requirements of the vehicles returning to the warehouse at a later time ma...
