Embodiment Construction

[0019] The principles and features of the present invention are described below in conjunction with the accompanying drawings, and the examples given are only used to explain the present invention, and are not intended to limit the scope of the present invention.

[0020] Step 1. Given a set of one-way tasks, the empty time matrix between the depot, the charging pile and the station, the battery capacity and charging time of the electric bus, and the minimum compatibility probability, the time compatibility is defined as the uncertainty of the one-way operation time In the case of , the ordinary arc and charging arc between two one-way trips and the exit arc and return arc between one-way and the parking lot can meet the time requirement probability. If the probability is greater than the minimum compatibility probability, the time compatibility requirement is met, otherwise Does not meet the time compatibility requirements. The exit arc and return arc must be able to meet the ...

Abstract

The invention discloses a method for dispatching electric public transport vehicles. The method includes: firstly specifying a one-way task set, an empty driving time matrix between a parking lot, a charging pile and a station, the battery capacity of an electric bus and the time required for charging; Sort according to the departure time from early to late; through the time compatibility and power compatibility between one-way, assign one-way to the train chain in turn to form an initial solution; extract some one-way through the solution destruction algorithm; then reconstruct the scheduling scheme through the repair algorithm ; Repeat until the termination condition is met. The method of the present invention can generate a vehicle scheduling scheme for electric buses; considering the randomness of the one-way time, the present invention proposes a calculation method for power compatibility, and describes the connectivity between one-way through probability together with time compatibility; by setting The lower bound of compatibility probability improves the robustness of the scheme, and then improves the service quality of public transport.

Description

technical field [0001] The invention relates to the technical field of public transport vehicle dispatching research, in particular to an electric public transport vehicle dispatching method. Background technique [0002] In recent years, with the continuous improvement of the level of urban modernization, the share of electric vehicles, especially electric buses, has gradually increased. At the same time, electric buses can alleviate energy shortage and environmental pollution to a certain extent, so governments of various countries are vigorously promoting the development of electric vehicles to promote urban energy conservation and emission reduction. However, due to the short mileage and long charging time of electric buses, it brings new challenges to the vehicle scheduling of public transport companies. In the process of dispatching electric buses, not only the timetable constraints, but also the power constraints and charging strategies of buses must be considered, w...
