【摘要】 随着市场竞争的不断加剧，产品成本成为企业能否赢得成功、求得生存的决定性因素。企业从自身发展需要，提出了应用信息技术，实现成本估算和核算的自动化的迫切需求，促进了成本管理信息系统的飞速发展。但是如何准确地对研究型企业的成本信息进行管理、如何建立集成环境下成本管理信息系统的开发框架、如何避免软件重复开发现象，都是我们面临的问题。为此，论文以西南电子电信技术研究所ERP系统为工程应用背景对研究型企业集成环境下的基于组件技术的成本管理信息系统进行了研究和开发。 论文首先对科研型企业的特点进行了探讨，提出了科研型企业实施管理信息系统必须解决的问题。在充分考虑与其它子系统集成的情况下，给出了研究型企业成本管理信息系统的总体设计方案，并采用IDEF建模规范建立了系统的功能模型和信息模型。 论文在详细设计的基础上，采用简单易用的组件对象模型技术对系统进行了组件化开发。系统的开发采用客户机／服务器的开发模式，后端以Oracle8.16作为数据库管理系统，前端以Delphi6.0作为开发工具，并给出了系统运行的结果。 论文在系统开发完成之际，对系统进行了总结，并对有待改进的地方提出了改进的构想。 论文的研究成果已经在西南电子电信技术研究所的生产管理中应用，并取得了良好效果。更多还原

【Abstract】 With the increasing competition of the market, product cost has become determinant for enterprises to survive and succeed in competitions. Enterprises have realized the importance to manage cost information with computer and already actualized cost information management system more or less. But how to manage the cost information accurately, how to present a platform for cost information management in integrated environment and how to avoid the repeated work in system development are problems faced by us. Therefore, the paper discusses and develops the component-based cost management information system for enterprises of research type in integrated environment on the basis of Southwestern Electron and Telecom Technology institution (SETT)’s ERP project.Firstly, the paper compares the difference between mass production and muti-type & small-batch production, enumerates a series of problems to be solved in actualizing management information system for enterprises of research type, presents the total design of the system with full consideration of the integration with other subsystems and establishes the function model and the information model of the system with IDEF modeling method.Secondly, the paper develops the system with simple component object model (COM) technology on the basis of the above design. The new system is developed on advanced C/S module, with Delphi 6.0 as the desktop tool in clients and Oracle 8.16 as the database management system in server.Finally, the paper discusses and analyses the result, presents the idea to improve the system.The eighth department of SETT has put into use the cost management information system and greatly increased the efficiency of cost management work.更多还原
