Application And Research Of Pso In Express Delivery Based On LBS

As a new industry, Express is changing people’s consumption patterns and habits.Express delivery, is the last part of the distribution.At present, in the delivery stage, companies are still using the tradition of the management process, mainly express delivery route planning is not reasonable, the courier attendance management inconvenience, courier position information acquisition difficulties and courier receipt of information to real-time feedback problems.The rapidly growing popularity of LBS technology rapid development and smart phones, to solve the problem provides an opportunity lbs technology is applied to the express delivery management, realize the new management mode of express delivery, planning the best delivery path, have great significance by improve delivery efficiency.With study of the express delivery management status and related information technology, analysis the problems existing in the express delivery deeply, and puts forward the corresponding solutions.With in-depth analysis on the the optimal path problem of express delivery, can transforming it into the problem of TSP, constructed optimal delivery path planning mathematical model and particle swarm optimization algorithm in the optimal path planning application model, and the use the particle swarm optimization algorithm to solve the optimal path.Aiming at solving the problem of large fluctuation, it is easy to fall into local optimum, and it is time consuming,To solve these shortcomings, the improvement measures are put forward,The application of the classical example and the design of the express delivery examples of simulation comparative analysis of experimental results,The experimental results show that the improved PSO algorithm to solve the optimal delivery path is better.And then use the improved PSO algorithm to find the optimal route of delivery.In order to acquire the real time position information of express delivery,Combine the eagle eye trajectory service of Baidu LBS cloud platform,with Android system positioning module,To achieve the location of the courier to collect information, and upload to the cloud, managers through the Web management to achieve real-time positioning of the courier and track playback.Also the real-time receipt information of express will be uploaded to the server by the client of Android, Use the pittings to display the condition of distribution in Baidu map for the managers.According to the solution of the problem, using Java EE and MVC software design model construction of the express delivery system web management, the use of Android development of technology implementation of the LBS service of the system and the system of the Android client,Use Web service to complete data interaction between the mobile terminal and server.Had achieve the main function of express delivery management systembased on LBS,Including provide managers LBS real-time positioning and historical track playback and delivery complete real-time view;Provide the function of managing delivery task and planning the optimal path for courier.
