Aiming at the concrete need in srttep construction and embodying the managing theory of the combination of the prearranging programming and comprehensive control , the article proposes the cpm - based schedule operating program of srttep on the basis of the relationship among schedule program , cost and quality which thus realizes the close combination of schedule program and project control ; based on the comparative analysis of experience estimation method , factor estimation method , wbs estimation method and comparison estimation method , the cost controlling strategy is worked out that attaches importance to the srttep cost budget and market economy situation . meanwhile , comprehensive quality management theory is introduced in the project " s schedule program . aiming at subsidiary project bidding , equipment purchase , essential quality inspection , detailed quality insurance system and rules are worked out so as to achieve the goal of high - quality construction of srttep ( 3 )针对川塔项目施工建设具体需要，在充分体现项目事前规划与全面控制相结合管理思想和所进行的项目wbs结构分解基础上，基于项目进度? ?费用成本? ?质量三者之间的关系，提出了基于cpm关键路线法的川塔项目进度计划制定方案，实现了进度规划与控制的紧密结合；在对比分析经验估算法、因素估算法、 wbs估算法、类比估算等方法和技术基础上，制定了侧重于预算的川塔项目成本基本规划方法，以及结合市场经济情况的成本控制策略；同时将全面质量管理思想，引入了项目施工方案中，针对子项目招标、设备采购、重点质量监控点等设立了详细的质量保障机制和细则，以确保达到工程优质建设的目标。
The thesis discusses the design process based on axiomatic design . the designer goes through a process whereby he / she can zigzags between domains - functional , physical , completes the decomposition and judges the independence of function and the consistency of decomposition 本文以公理设计为理论依据，应用公理设计理论设计框架，通过功能域和结构域之间的映射变换，完成产品的功能结构分解以及功能独立性和设计分解一致性的分析，得到产品的等级结构模型，和各个组成部分之间的相互影响关系。
Secondly , wbs is applied to the construction decomposing , we can optimize and modulate the project scheme via project 2000 software to find out the critical route . thirdly , we use the method of analysis based on reason and result to control the project construction quality . finally , the earned value ( ev ) is used to effectively test and control the expense and scheme . on the basis of experience , the author combines the most economical equipment endurance with value engineer ( ve ) 在项目的规划、实施等关键阶段，用wbs对工程项目的进行结构分解；再利用projeot2000软件进行施工进度的优化和调整，找出关键路径；运用国际上先进的挣得值原理( ev )对费用、进度进行有效的测制和控制；用因果分析的方法对施工质量问题进行分析和控制；作者结合多年设备管理的经验，将“设备寿命周期最经济”的思想与价值工程( ve )相结合，应用于技术方案的选择和设备的选型；在组织结构方面，设计了“大小枢纽结构”的方法。
( 2 ) . wbs is an important basis in project management and a necessary clue of activity chain . taking the aim and function of the srttep plan as a starting point in consideration , with the introduction of the prearranging ideas such as concept design , detailed design and rolling design , the thesis puts forward project working structure resolving method based on wbs three - class model , thus realizing the working structure resolution by using gradually - deepened gradation model and laying foundation on better plan , staff disposition and budget plan ( 2 )项目工作结构分解( wbs )是项目管理的重要依据和活动链接的必要线索，本文从川塔施建工程项目工作计划的目的和作用出发，引入概念设计、详细设计、滚动设计的事前规划思想，提出了基于wbs三级模型的项目工作结构划分方法，利用逐级深入的层次模型实现项目的工作结构分解，为项目进一步的进度计划、人员分配、预算计划奠定了坚实的基础。
A planar sidm with j loops ( expressed in term of smj ) can be regarded as comprising of a sidm with j - loops ( expressed in term of smj - 1 ) and a dyad ( expressed in term of dyadj ) . then , the circuit condition of sm , is determined by the circuit condition of smj - 1 and the configuration of dyadj . based on the above thought and combined with the automatic generation of structural decomposing of planar mechanism according to the type transformation theory , circuit automatic identification of planar sidm are realized , two examples are given to demonstrate the use of this method 具有j个环路的sidm可看作由j - 1个环路sidm与一个双杆组(记作dyad _ j )组成，则sm _ j的回路情况由sm _ ( j - 1 )的回路情况、 dyad _ j的构形以及dyad _ j与sm _ ( j - 1 )运动的相互作用决定，基于此思想，在全面分析了所有类型双杆组的构形及装配条件的基础上，与型转化法机构结构分解路线的自动生成相结合，实现了平面sidm回路识别的系统化与自动化；最后给出了两个分析实例。
Then after summarizing the development of bill - of - material system , the generic bill - of - material was used to representing the product family structure for mass customization . the configuration model based on the gbom and cbr was established under the direction of the independence of product model and configuration . and the process of case indexed was described from the point of view of the disassembling product function and product structure 首先综述面向大规模定制的产品设计技术( designformasscustomization ， dfmc )的理论基础，在探讨产品结构化方法发展过程的基础上，确定创成式bom方法为mc模式下产品族结构的描述方法；然后分析了产品配置的原理及配置器的推理方法，在产品模型与配置器分离思想的指导下，提出了适用于mc模式的基于gbom和cbr的产品配置方法，并从产品功能分解和产品结构分解的角度描述了实例检索过程。
