The information integrated pattern based on PDM/PLM in the course ofmanufacture is put forward. Under the constraints of building CAPP platform, thearchitecture of CAPP platform is established. The models of decision making andfunction for process planning are given. Then the development means of CAPP basedSmarTeam are extracted.3. The structure of modular product life cycle is established. Toward the divisionand planning of the General Modules oriented product family, theCAD/CAPP integrated model of flexible module based on feature and CAD/CAPPmapping model based on process planning match board are set up. The keytechnologies of Solidworks/SmarTeam/CAPP integration are studies.4. From the point of view of process match board and step match board, theprocess of creating to process planning match board is studied. As an example, themachining process planning of up beam of hydraulic press machines is used tointroduce the establishment of process planning match board by means of inferencebased on expert knowledge. The organize model about the process planning matchboard oriented product family is brought forward.5. The multi-decision methods of CAPP system based on analytic hierarchy aregiven.. On the basis of uniform data model, the sub-machining process planning ofpart is auto-created by means of analytic hierarchy, The step decision methods basedon AHP is put forward.6. For the design/manufacture information in the course of product life cycle, thetree structure based on Object-Oriented and static model based UML are founded. Themethod of establishing design/manufacture information management system isbrought forward. The commercial PLM software—SmarTeam is regarded asdevelopment platform, on basis of which, the design/manufacture informationmanagement system is built, and the multi-view mapping technique ofdesign/manufacture information model is studies.7. A computer-aided CAPP platform based on PDM/PLM is founded, and itsstructure, function, work flow is illustrated. Some example of the system areintroduced.

The former three chapters are about theoretical research, and the forth chapter is about empirical research. The theoretical research part generalizes the theoretical basis, theoretical model and the concept of city competitiveness both at home and abroad. According to these theories, the paper introduces the complete and explicit definition of city competitiveness and brings in a new city competitiveness model .The paper emphasizes on empirical research using the data in 2004 as sample, whose objects are ten big cities:Guangzhou, Shenzhen, Tianjin, Shenyang, Dalian, Nanjing, Hangzhou, Wuhan, Chongqing and Chengdu. Firstly, on the basis of mean square deviation method, it finds out both the scores of integrated competitiveness of cities and other factors, based on that analyze the relationship between them. And then the paper computes the scores of competitiveness of cities above by principal component analysis and sorts out them for assessment.
