Problems solved by technology

However, in the actual driving process of transport vehicles, the path optimization blindly pursuing the shortest distance as the objective function is no longer applicable, and it is necessary to comprehensively consider the actual conditions such as full-load delivery of vehicles, vehicle congestion at loading and unloading points, etc.

Embodiment Construction

[0014] In order to better understand the technical solutions of the present invention, further description will be given below with reference to the drawings and specific embodiments.

[0015] As shown in Figure 1, firstly, input vehicles, venues, and tasks into the computer, and use the computer to establish a three-dimensional full-load optimal scheduling model considering congestion control. details as follows:

[0016] There are six cargo tasks (j=1, 2, 3, 4, 5, 6) to be completed, and there are three venues (i=7, 8, 9), each of which has seven vehicles. Denote the freight task as A j , A j The freight volume is Q j , the time to load a car is P j , and the unloading time is set to D j , the freight volume, loading time, and unloading time of each task are shown in Table 1.

[0017] The distance d between the parking lot and the loading and unloading point is shown in Table 2. Among them, when 7≤abscissa (i)≤9, 1≤ordinate (j)≤6, d represents the distance between the...

Abstract

The invention discloses a method for dispatching the vehicle which is suitable for fully loaded dispensing, including three steps of: computer modeling, dispatching optimization calculating, dispatching project output. Vehicle, place and task are inputted into the computer, three-dimensional fully loaded optimization model is established using the computer under considering congestion control, two-stage dynamic heuristic algorithm is used for dispatching and counting for three-dimensional fully loaded optimization model, and the final dispatching project is acquired and transmittd to vehicle via radio network. The invention, considering the fully loaded dispensing of vehicle and congestion at the loading and unloading position, can reduce the number of vehicles which are added in advance effectively, and the idle rate of vehicle and the cost of transportation for the enterprise.

Description

technical field [0001] The invention relates to a vehicle scheduling method for logistics distribution, in particular to a vehicle scheduling method suitable for full-load delivery of freight vehicles. Background technique [0002] For the logistics industry, the performance of the vehicle scheduling method directly affects the transportation efficiency. To improve transportation efficiency, it is necessary to rationally dispatch vehicles, optimize transportation routes, and reduce transportation costs. However, in the actual driving process of transport vehicles, the path optimization blindly pursuing the shortest distance as the objective function is no longer applicable, and it is necessary to comprehensively consider the actual conditions such as full-load delivery of vehicles and vehicle congestion at loading and unloading points. Contents of the invention [0003] The purpose of the present invention is to provide a vehicle dispatching method suitable for full-load ...
