| The problems of fruit characteristics are barely considered in the traditional logistics system for which the function of matching and pontificating information is necessary. This paper aims to study and develop a system for matching distribution information of fruit, to facilitate sales and transportation of fruit market, and improve farmers’ income. By analyzing the characteristics of fruit logistics, Android mobile devices was selected as a developing platform. The distance nearest method was combined with the C.W. saving algorithm to study the methods for matching information and planning vehicle routing in fruit distribution. The application of the system was feasible to distribute sales information timely and generate an optimal route for delivering, which promoted the development of the fruit market. The main research contents and conclusions of this study are as follows:(1) The demand of matching information for fruit distribution has been analyzed. The demand of fresh fruit is growing all over the country, but the fruit was planted in the specific region in China. Therefore, the delivering is an important part of the fruit industry. By analyzing the characteristics of fruit distribution, the logic of the information distribution was declared, and the system demand was analyzed to determine the input and output of the system, which made foundation for developing and building the system.(2) The mathematical model for calculating the optimal route of for delivering fruit was established. Taking the multiple distribution center and the time window as the constraint conditions,a two-stage algorithm based on the nearest method and the improved C.W. saving algorithm was used. In the first phase, according to the users distribute on a large scale, multiple distribution centers were applied. Nearest distance method was used to transfer the multiple centers problem into a single center problem. In the second stage, because the fruit is rot in a short time and hard to ship, this study took the time restriction into consider to build the route planning model. Based on the traditional C.W. saving algorithm, the time window for delivering was taken into account, by which and the optimal distribution route of the vehicle was obtained. The value of the three methods were compared, and the result showed that the total distance of route and time consumed deceased 12.21% and 12% respectively.(3) The information matching system for fruit distribution was developed based on Android mobile phone platform. Based on the model for fruit distribution, an application has been developed using Android and C/S architecture. The system was able to publish and search the vehicle and fruit information, and the information to users after matching the vehicle and fruit information automatically. The system was feasible to improve the efficiency of fruit distribution. |
