摘 要 随着国家对煤炭市场的放开，煤炭企业面临的竞争环境越来越激烈。运销工作是煤炭企业发展的命脉，但是传统的基于手工和单业务系统的煤炭运销管理和运作模式，存在销售流程繁杂、信息收集困难、信息沟通不及时、易出错等弊端，已经越来越不适应煤炭企业发展的需要。如何利用先进的信息技术和网络技术优化业务流程、提高工作效率，快速响应市场需求，是煤炭企业生存和发展的关键。 本文以陕煤集团运销工作为背景，结合目前管理信息系统的发展现状和销售管理部门的实际情况，在管理信息系统和软件工程的理论基础上，提出了陕煤运销信息管理系统的研究方法和设计思路并加以实现。首先分析了陕煤运销集团销售分公司运销系统的现状和存在的主要问题，并深入分析了形成问题的原因；其次针对当前的问题进行了归纳并提出了煤炭运销管理系统的信息模型；再次完成了本系统的需求分析、概要设计和详细设计；然后采用三层B/S模式，应用.NET平台、Visual Studio.NET 2005开发环境、SQL Server 2005数据库管理系统实现了该系统；最后对系统进行了标准化流程测试，测试表明该系统达到了设计功能和应用要求。 本系统将计算机网络技术与煤炭运销工作相结合，实现了煤炭运销工作高效有序地自动化管理。实践证明，该系统解决了原煤炭运销工作中存在的问题，优化了管理流程，提高了工作效率，节约了成本，为煤炭企业提高自身竞争力提供了有力的支持。

ABSTRACT Along with the opening of coal market, coal enterprises are facing more and more drastic competitive environments. Transportation and sales is the lifeline for the development of a coal enterprise. But the traditional mode, based on manual and single business system, has some disadvantages such as selling process miscellaneous, collecting information difficult, information communication not prompt, error-prone and etc. So, it can’t meet the needs of the requirement of coal enterprises development any more. The key for a coal enterprise to survive and thrive is to make full use of advanced information technology and network technology to optimize the business processes, raise work efficiency and response quickly to the market requirement. Based on the background of coal marketing management in Shaanxi Coal Group, taken the present situation of the management information system and the actual situation of sales department into consideration, this paper proposed a research method and design idea for Shaanxi coal transportation and sales information system on the basis of management information systems and software engineering. Firstly, introduced the present situation of transportation and sales information system, discussed the existing problems and analyzed the causes of these problems in detail. Secondly, based on the existing problems, we presented the information model of the coal transportation and sales system. After that, we completed requirements analysis, preliminary design and detailed design of the system. Then, implemented the system which is constructed under three B/S layers structure, applied to .NET platform, developed by Visual Studio.NET 2005 and SQL Server 2005 database. Finally, this paper tested the system according to the standardized testing procedures. The results show that the system meets the demands of designed functions and application. Combined the computer network technology with the coal marketing management, this system is an automatic management system that makes marketing management efficient and orderly. As verified in practice, the system solves the problems of traditional system, optimizes the management process, improves productivity, saves the costs and provides strong support for the coal enterprises to improve their own competition.
