【摘要】：近年来,随着PC端进销存管理系统的普及,使用者越来越感觉到单一的PC端系统已经不能满足大量数据的录入、流转。针对快消品行业的商品高流转的特性,固定地点、固定PC电脑进行数据采集的传统模式已经不适合。在这样的背景下,PDA(个人数字助理)的可携带、可移动的便捷特性弥补了 PC端进销存管理系统的不足,两者数据共享、紧密配合。目前,快速消费品行业已逐步开始利用PDA进行业务抄单、仓库管理等业务,极大地提高了工作效率。但是,商品出库以后的送货过程,作为商品配送流程的一个重要环节,还没有利用PDA进行有效管控,快速消费品的送货过程仍处于落后的状态。本文研究基于PDA的快消品送货系统的分析、设计和实现过程,主要完成以内内容:1、通过对快消品行业送货流程和进销存系统的分析,提出了优化方案。本系统提出以中间平台为桥梁,连接进销存管理系统和PDA终端,使PDA端程序和进销存系统共享业务数据。再采用面向对象的思想,结合实际需求对中间平台、PDA端软件进行功能设计,设计出运行流畅、操作便捷的快速消费品送货系统。2、提出采用WCF作为后台交换接口,把WCF后台接口交给Windows Form开发的中间平台托管。这样,中间平台安装部署好后,启动时同时也发布了后台服务接口,这样方便客户安装以及后期的维护。3、为了保证PDA端业务主程序运行流畅,开发了一个独立于主程序的GPS功能程序,专门用来采集和发送GPS信息。由于GPS坐标不能在百度电子地图直接显示,如果直接显示会存在误差,为了准确显示坐标位置并且可以显示相应的时间,利用百度地图API设计出了一个批量转换功能,可以准确的把GPS经纬度转换成百度电子地图自己的经纬度信息,最后在电子地图上显示坐标点和相应时间。这样使得管理人员在中间平台上可以准确地查看到外出送货人员的行车轨迹。4、为了实现送货路线规划,首先根据送货客户的详细地址,利用百度地图API的搜索功能统计出各个客户之间的时间距离、空间距离并保存到中间平台数据库中。然后,以客户之间的距离数据为依据,使用贪心算法对送货路线进行规划,向送货人员给出各个客户的送货顺序以及所要花费的时间或路程。5、采用成熟的.NET框架开发中间平台和PDA端软件,实现装车验货、送货验货、资料下载、单据查询、清车处理、GPS功能、系统设置等功能。本系统在实际使用过程中,运行良好,以其便捷性、稳定性使得送货过程的准确率显著提升。尤其是送货人员的行车轨迹可以准确的显示在后台,实现了对送货过程的有效管控。快速消费品送货系统的开发,提高了快消品行业的信息化管理水平,降低了快消品批发商的运营成本。
[Abstract]:In recent years, with the popularity of PC system, users feel that a single PC system can not meet a large number of data input and circulation. In view of the characteristics of high flow of goods in fast goods industry, fixed location, fixed PC computer for data acquisition is no longer suitable for the traditional mode. In such a background, PDA (personal digital assistant) portability, portability and convenience make up for the shortcomings of PC end purchase, sale and storage management system, the two data sharing, close cooperation. At present, the FMCG industry has gradually started to use PDA to carry out the business such as order reading, warehouse management and so on, which greatly improves the working efficiency. However, as an important part of the commodity distribution process, the delivery process of goods out of the warehouse has not been effectively controlled by PDA, and the delivery process of fast moving consumer goods is still in a backward state. This paper studies the analysis, design and implementation process of fast product delivery system based on PDA. The main contents are as follows: 1. Through the analysis of the delivery process and the purchase, marketing and storage system of fast consumer goods industry, the optimization scheme is put forward. In this system, the intermediate platform is used as a bridge to connect the system and the PDA terminal, so that the PDA program and the system can share the business data. Then using the idea of object-oriented, combined with the actual requirements of the intermediate platform, PDA terminal software for functional design, designed a smooth, easy to operate FMCG delivery system. 2, put forward the use of WCF as the backstage exchange interface, WCF background interface to the Windows Form development of the intermediate platform hosting. In this way, after the intermediate platform is installed and deployed, the background service interface is also released at the same time when starting, which is convenient for the customer installation and later maintenance. 3. In order to ensure the smooth running of the main program of the business on the PDA side, A GPS program independent of the main program is developed, which is used to collect and send GPS information. Because the GPS coordinates can not be displayed directly on the Baidu electronic map, if there are errors in the direct display, in order to accurately display the coordinate position and display the corresponding time, a batch conversion function is designed by using the Baidu map API. Can accurately convert GPS latitude and longitude into Baidu electronic map of their own latitude and longitude information, finally in the electronic map display coordinates and the corresponding time. This makes it possible for managers to accurately view the track of outgoing delivery personnel on the middle platform. 4. In order to plan the delivery route, first of all, according to the detailed address of the delivery customer, Using the search function of Baidu map API to calculate the time distance and space distance between each customer and save them in the middle platform database. Then, based on the distance data between customers, using greedy algorithm to plan the delivery route, give the delivery order of each customer and the time or distance. By using the mature .NET Framework to develop the intermediate platform and PDA terminal software, the functions of loading and inspection, delivery inspection, data downloading, document inquiry, car cleaning processing, GPS function, system setting and so on are realized. The system runs well in practical use, and the accuracy of delivery process is improved significantly because of its convenience and stability. Especially, the track of the delivery personnel can be accurately displayed in the background, which realizes the effective control of the delivery process. The development of fast consumer goods delivery system improves the information management level of fast consumer goods industry and reduces the operating cost of fast consumer goods wholesalers.
