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 method for arranging return lanes of subway car depots. This method includes the following steps: first, collect the vehicle information and stock track information required by the algorithm, and establish a parameter set for the actual problem; second, select an appropriate encoding method to construct the chromosome and formulate population initialization rules to generate Z The chromosomes constitute the initial population P; then the optimization objective function and constraints are determined according to the actual problem; finally the individual selection rules and specific operation methods of hybridization and mutation are determined, and the fitness value of each individual is calculated according to the fitness function and the individual with the largest fitness value is evaluated. Save and repeat the operation until the maximum number of evolutionary generations. This invention can make reasonable choices about train tasks and find the best track arrangement plan under resource constraints, provide decision support for subsequent daily inspections and shunting operations, and greatly improve the efficiency of depot operations.

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...
