Embodiment Construction

[0033] The present invention will be further described below in conjunction with the accompanying drawings.

[0034] A vehicle-based path planning device according to an embodiment of the present invention includes:

[0035] A route storage module, storing at least one route plan, each route plan including a departure point, at least one destination and at least one path information from the departure point to the destination;

[0036] The processing module processes the path schemes in the path storage module according to the exchange, insertion, same-path swap, exchange and / or reverse exchange rules in the processing module, and stores all the path schemes obtained after processing in the in the path storage module; and,

[0037] The comparison module compares all the path schemes obtained after processing according to the preset principle of the shortest time, the shortest path and / or the lowest cost, and obtains the optimal path scheme.

[0038] The path schemes all form...

Abstract

The invention discloses a planning device and a planning method based on a vehicle path. The device comprises a path storage module for storing at least one path scheme, wherein each path scheme comprises a departure place, at least one destination and at least one path information from the departure place to the destination; a processing module for processing the path scheme in the path storage module according to transposition, insertion, interchange of the same path, exchange and / or reverse exchange in the processing module, and storing all processed path schemes into the path storage module; and a comparison module for comparing all processed path schemes according to the preset shortest-time, shortest-path and / or lowest-cost principles and obtaining an optimal path scheme. According to the invention, five neighborhood construction planning methods are designed, a search range of the path information is increased and an optimal path scheme combination with high quality for the problem is obtained so that the logistics distribution cost is reduced and the distribution efficiency is improved.

Description

technical field [0001] The invention relates to the field of engineering technology, in particular to a vehicle-based path planning device and planning method. Background technique [0002] Vehicle routing planning is an abstraction of practical application problems in many fields such as logistics center distribution, solid waste collection, street cleaning, letter and newspaper delivery, and bus routing. Although this problem has been proved to be one of the NP-hard problems, it has been widely concerned by scholars at home and abroad because of its wide application and great economic value. [0003] In the neighborhood construction method, if one solution is called another solution through some transformation, then the two solutions are neighbors. Generating a new solution from the initial solution, and using it to generate a better solution, are all neighborhood construction processes. It is often used as a part of the optimization algorithm, which can greatly increase...
