On the basis of collecting and processing many datum and materials . firstly . this paper analyzes main activities and cost constitutions of each stage of the life cycle of a fcs , and lay a foundation for later analysis and evaluation of system lcc . secondly , a basis method and usage range for estimating the system lcc are introduced . a multivariate linear regression model of pcs development cost and cost driven factor is built by use of the parametric method and supplies the base of cost estimation of newly - developed systems . thirdly , combine actual examples and make statistical analysis of lcc of a certain pcs developed by our institute , predict unhappened usage and service cost with grey prediction method , obtain proportion of each constitute to the lcc . forthly , according to actual conditions , use the fuzzy theory to overall evaluate efficacy of the fcs , fifthly , combimng our actual conditions , investigate specific measures of how to implement the life cycle cost management in our institute and put forward a new conception of developing web - based flight control system lcc management information system with pdm as the platform . at last , investigate important factors such as reliability and maintainability that may affect the life cycle cost of the fcs in detail , and put forward specific methods of lowering the life cycle cost of the fcs 论文在收集和整理大量资料的基础上，首先深入分析了飞控系统寿命周期各阶段的主要活动以及各阶段的费用构成，为以后系统寿命周期费用的分析和评价奠定了基础；其次，介绍了寿命周期费用估算的基本方法和使用范围，并利用参数法建立了飞控系统研制费用与费用驱动因子的多元线性回归模型，为新研系统的费用估算提供了依据；第三，结合实例对我所研制的某型飞控系统的寿命周期费用进行统计分析，运用灰色预测方法对未发生的使用及维修费用进行预测，得出了该系统的寿命周期费用以及各组成部分所占比例；第四，根据实际情况，首次运用模糊理论对飞控系统的系统效能进行了综合评价，构造了飞控系统系统效能模糊综合评价模型；第五，结合我所实际，探讨了如何在本单位实施加强寿命周期费用管理的具体措施，提出以pdm为平台，开发基于web的飞控系统lcc管理信息系统的新构思；最后，对影响飞控系统寿命周期费用的重要因素如可靠性和维修性等进行了详细地研究，提出了降低飞控系统寿命周期费用的具体方法。
This paper has expatiated the telecommunication integration service management system ’ s design thought and realization , and it ’ s importance in the telecommunication business / operation supporting system , and on the bases of analyzing business demand , it sets up an oracle database for sharing information with other subsystem of the business / operation supporting system , using programming language delphi to develop the telecommunication integration service management system front application program at the same time , the ones that have realized to various kinds of telecommunication service accept and fee management , the automatically legitimacy check of user ’ s message , the real - time inquire of user ’ s information , the business acceptance ’ s inquiry and statistic etc . 本文详细阐述了电信综合服务开通系统在软件设计上的思路和具体实现,阐明了电信综合服务开通系统在整个电信运营支撑系统中的重要性。并且在分析业务需求的基础上,建立能与电信运营支撑统的其他子系统共享的大型oracle数据库,同时利用可视化编程语言delphi开发了电信综合服务开通系统前端应用程序,实现了对各种电信业务的受理和费用管理,以及受理用户信息合法性的自动检查,用户信息的实时查询,业务受理情况的查询与统计,系统维护等多种功能。
Control of cost and expense on developmental project of real estate penetrate in entire project construction process , therefore , we must take highly to the organization and the control measures , by enhancing management and control of cost and expense , comprehensively control the construction cost and operation cost in entire project cycle , only this can reduce total cost of real estate development project to enhance economic efficiency of real estate enterprise 房地产开发项目成本费用控制贯穿于项目建设的全过程,必须在组织、技术、经济和合同等措施上予以高度重视,通过加强成本费用管理、控制成本费用支出,在工程项目整个周期内全面监控其建造成本和营运成本,这样才能降低房地产开发项目的总成本,以达到提高房地产企业经济效益的目的。
It project management contains nine fields of knowledge : the management of project scale , the management of item , the management of cost , the management of quality , the management of risk , the management of stuff , the management of purchasing , the management of communication , and the macro management of item 项目管理包含项目范围管理、时间管理、费用管理、质量管理、风险管理、人员管理、采购管理、沟通管理、项目整体管理等九大知识领域和项目启动过程、项目计划过程、项目执行过程、项目监控过程、项目收尾过程等五大项目过程。
Till now , there were four stages in the development of technical maintenance , after repair , beforehand repair , daily maintenance and integrated management . nowadays , to maximize the entire efficiency the technical management , many shipping companies have introduced the policy of life cycle cost management and total productive maintenance and logistics 如今，典型的设备管理模式在理论上大都融合了“全寿命周期费用管理、全员生产维修和后勤工程学”等思想精髓，注重设备在设计和制造阶段的前期管理，追求设备管理全过程综合效益的最大化。
