Method and system for dynamic vehicle dispatch

Abstract

A method and system for dynamically dispatching vehicles with good real-time performance and accuracy, the implementation is simple and reliable, suitable for real-time vehicle scheduling in the logistics company park, which can solve the problem of accurate positioning and real-time scheduling of logistics vehicles when the logistics vehicles are too dense in the logistics company park, effectively improve the congestion of logistics vehicles in the logistics park, and improve the efficiency of vehicle scheduling in the park. The technical scheme is as follows: Firstly, the RFID reader obtains the relevant information of each logistics vehicle arriving in the logistics park, and then determines the relevant information of a vehicle near the logistics vehicle, and then adopts the prioritymulti-service window waiting system M / M / n queue model to dynamically dispatch the logistics vehicles according to the accurate location of the obtained logistics vehicles.

Description

technical field [0001] The invention relates to vehicle positioning and dynamic scheduling technology, in particular to a dynamic scheduling technology for vehicles in logistics parks based on queuing theory. Background technique [0002] With the rapid development of e-commerce and other industries, logistics companies have more business of delivery and unloading, which makes a large number of logistics vehicles enter and exit the factory area. However, these vehicles have no effective information guidance in the factory area. There are a series of problems such as vehicle congestion in the factory area, low unloading efficiency, and untimely delivery. These problems also make the business efficiency low, seriously restricting the development of logistics companies. It is difficult for traditional vehicle dispatching to meet the real-time, high-efficiency, and low-cost requirements in the current e-commerce environment. At present, some logistics companies have introduced...

[0002] With the rapid development of e-commerce and other industries, logistics companies have more business of delivery and unloading, which makes a large number of logistics vehicles enter and exit the factory area. However, these vehicles have no effective information guidance in the factory area. A series of problems such as vehicle congestion in the factory area, low unloading efficiency, and untimely delivery

These problems also make the business efficiency low and seriously restrict the development of logistics companies.

Traditional vehicle scheduling is difficult to meet the real-time, efficient and low-cost requirements in the current e-commerce environment

At present, some logistics companies have introduced the GPS logistics vehicle dispatching system considering the needs of cargo transportation. However, the GPS signal weakens seriously when the high-rise buildings are densely packed or when there are viaducts, tunnels, etc., and in some mountainous cities. The medium signal strength is very weak, which will cause the GPS system signal to be unstable or even not work properly

At the same time, because the signal of the GPS dispatching system is interfered, the logistics vehicles will often report falsely when they report to the station, making real-time, stable and accurate vehicle dispatching in the logistics park become a very difficult issue.
