【摘要】 技术改造是提高企业经济效益的关键环节,是企业赖以生存和发展的永恒主题,技改管理工作的规范化和效率化,对企业发展具有重要的意义。信息技术的广泛应用为企业信息资源的共享和即时传输提供了良好的硬件环境和技术支持。管理信息系统(MIS)作为企业管理的一种现代化工具,促进了企业的有效运行。本文是以“西航公司技术改造项目管理信息系统”(430-PMIS)的开发为背景进行研究的。 本文采用结构化系统分析方法,在对西安航空发动机(集团)有限公司技术改造处的实际情况进行需求分析的基础上,确定了“西航公司技术改造项目管理信息系统”(430-PMIS)的总体方案,制定了系统的信息流程;采用结构化系统设计的方法,对整个系统及其各组成模块进行了系统划分和功能设计,并完成430-PMIS系统的数据库设计、代码设计以及输入输出设计;然后,对430-PMIS系统的计算模式进行选择,并描述了软件的运行及开发环境,针对430-PMIS系统主要模块功能的实现进行了探讨。 最后,结合软件系统的开发情况,对本系统开发中的几个关键问题如,在PB中实现大文本数据的ftp传输、在PB中实现异构数据库间的数据转换、系统权限分配等进行了深入研究,这些问题在本系统中的解决方案也可以作为其它信息系统设计、开发的参考依据。

【Abstract】 Technique innovation is a pivotal factor in improving enterprise’s economic benefit, it is also important for enterprise to get its existence and development. Technique innovation management plays an important role in enterprise management. Accompanying with the development of computer technology, information technology is widely used. This can support the transission and share of the enterprises’ information. MIS is an advanced tool for the enterprise and improves the effective running of the enterprise. The research of this paper is based on the development of Management Information System of Technique Innovation Office in Xi’an Aero-Engine (Group) Ltd. (430).By using the structural system analysis method, the scheme of 430-PMIS is established and the information flow of the whole system is confirmed on the basis of analyzing the practical requirements of technique innovation management in 430. By using the structural system design method, subsystems are divided and their functions are designed. The database, code, and I/O are also designed. Then, the computing paradigm of 430-PMIS is chosen, the developing and running environment of this software is described, and the realizing procedure of some important functions of 430-PMIS is discussed.At the end of this paper, according to the development of 430-PMIS, some important problems, such as the realization of ftp transfer in PB, data transformation of heterogeneous databases in PB, and system authority distribution, are also discussed. The solved methods in this system can be applied in the development of other information system.
