Study On Process Modeling Of Conceptual Design Oriented To Collaborative Product Innovation And Its Key Technologies

In the environment of fierce worldwide market competition, product innovationhas become one of the main modes of enterprise’s economic growth, which is a keyfactor for enterprises to establish the core competitiveness. On one side, the fiercemarket competition makes the product innovation cycles becoming shorter and speedbecoming faster, on the other side, product innovation has a higher risk and uncertainty,so that enterprises are facing unprecedented innovation pressure and risk. AS a newmodel of innovation, collaborative product innovation can take full advantage ofinnovation bodies’ innovative experience and knowledge, and help to enhance theirproduct innovation capability. Therefore it gets more and more concern from thebusiness community and academia. In the process of collaborative product innovation,conceptual design is the most active, and creative front, and it is a critical stage to buildfor the innovative design scheme. On the collaborative conceptual design of productinnovation, the systematic research has yet to be retrieved, so that which the research onit has important theoretical value and practical significance.Therefore, on the basis of researching the latest theoretical achievements aboutcustomer collaborative innovation, the process modeling of conceptual design orientedto collaborative product innovation and its key technologies are studied. The maincontents of the thesis consist of the following parts.①Oriented to collaborative product innovation, the process model of conceptualdesign was studied. Firstly, the basic theory of product conceptual design was analyzedsystematically, including its basic definition and process. Secondly, of the basic types ofcollaborative innovation body and the basic features of collaborative innovationorganization were studied. Furthermore, the basic characteristics of the conceptualdesign oriented to collaborative product innovation were analyzed, and the basicframework of conceptual design oriented to collaborative product innovationconstructed. On the basis, process model of t the conceptual design oriented tocollaborative product innovation was built, which is the theoretical foundation forsubsequent research.②Oriented to collaborative product innovation, the construction method ofconceptual design target system was studied. Firstly, based on systematic study of the"push" and "pull" innovative needs, the basic framework of collaborative production innovation target system was constructed, which containing economic, structural,environmental, technical and functional basic dimensions. On the basis, a quantifiedapproach based on third-stage combining subjective and objective methods includingAHP and entropy value method, multi-granularity non-equilibrium semantic treatmentmethod and so on was proposed to calculate and revise the importance of target. Finally,the feasibility and effectiveness were verified by an example.③Oriented to collaborative product innovation, the evaluation method ofconceptual design scheme was studied. A systematic, hierarchical and rationalevaluation index system of conceptual design scheme is established, following theprinciple of scientific combining with systematic, connectivity adapting to Hierarchy,and purpose united with feasibility,. On the basis, an evaluation method of conceptualdesign scheme based on R-A-WNN is proposed. Firstly with the use of rough setstheory(RST), the evaluation indicators are pretreated Secondly, based on WaveletNeural Network(WNN), a basic network model of scheme evaluation was built, and Antcolony optimization (ACO) was used to optimize the key parameters for simultaneously.Finally, an example was given to illustrate the feasibility and effectiveness of theproposed method.④Oriented to collaborative product innovation, an optimization method of theconceptual design based on parameter-driven was studied. Firstly, combining thefeatures of product innovation conceptual design, the program parameter optimizationproblem was described systematically. Secondly, based on QFD theory, an optimizationmodel for conceptual design parameters design was constructed. It makes full use of thedifferent innovation agents’ knowledge, to solve the mapping problem betweenInnovation expectations and scheme parameter. Finally, the case was studied thatcharacter parameters were optimized, with maximum satisfaction. The effectiveness andfeasibility of the method is verified.⑤Oriented to collaborative product innovation, an optimization method of theconceptual design based on the intelligent reorganization was studied. Firstly, with theaim of scientific orientation of innovative points from the innovation schemes proposedby every innovation main body, the types of innovation have been studiedsystematically, and its classification method is proposed. Furthermore, an innovationevaluation method based on rough sets theory is raised by which we can describequantitatively the innovation level of different innovation points. On this basis, anoptimization method of the conceptual design based on the intelligent reorganization was proposed, by which specific innovation demands can be satisfied. Finally, anexample was given to illustrate the feasibility and effectiveness of the proposed method.
