Study On The Model Of User’s Participation And Group Collaboration In Product Nnovation

The importance of product innovation has been realized gradually in domestic industries. Increasing innovation behavior will soon demand for large amount of developers, and will probably cause shortage in human resource supply. The subject of the thesis——user’s participation in product innovation——aims at the exploring of ordinary user’s innovative resource, including both single user and group users. The thesis studies mainly three subjects of user innovation:1) mechanism of ordinary user’s participation in product innovation;2) aiding techniques;3) group users’ collaboration style under non-contractual state.Considering the three subjects, the thesis carried out research work on user toolkit of innovation (UTI) and users’collaboration through theoretical modeling and experimental study. An information stream model of user innovation is established based on1-Space frame. On the background of user innovation’s learning loop features, the feasibility and practicability of genetic algorithms are discussed and interactive genetic algorithms (IGA) is chosen as the technical tool for constructing UTI. Group users’collaborative innovation (CIGU) is studied through experiments, together with aiding techniques of UTI for the main processes, and a web-based CIGU mechanism is designed. A proto-system is established, in which the techniques are tested with typical examples.The contents and research conclusions of the thesis are as follows:1. An information stream model is constructed based on Boisot’s I-Space frame. User-belonged information resources for product innovation are positioned in the3D space. Information processing methods are expressed as moving paths in I-Space, in which different roles——professional developers, users and aiding techniques——are discussed. The feasibility and conditions for replacing the first with the other two are analyzed. The paths are evaluated from the view of information transaction costs. With the help of information stream model, the author analyzed the four basic features of UTI proposed by Von Hippel:learning loop, friendly interaction, modularity and boundary. Moving paths of the four features in I-Space are observed, from which the aiding technique’s properties for realizing learning loop are given. 2. The thesis constructed a UTI technical frame based on IGA, whose traditional evaluation methods are improved. A Boolean evaluation method is designed and proved useful in reducing user’s evaluating fatigue. In the UTI model, key aiding techniques are designed for each stage of user’s learning loop in I-Space, such as embedding of exterior knowledge, recognision of sensitive factor, utilitiy of sentive factor, visualization of evolutionary situation and evolution control. The techniques are tested with experiments in user innovation.3. The thesis proposed a collaborative innovation method for group users (CIGU), and derived five features of CIGU through analysis:value accumulation, information propelling, small world generating, labor division and the guarantee of related people. Designed a collaboration method based on citing and carried out experiments. With a comprehensive consideration of consistence and convergence target, the author designed the collaboration model including profit allocation plan. Features of CIGU are observed through the experiment results, and the collaborative method’s feasibility to product innovation are proved from the view of concentration, citing pattern, optimality conditions, collaboration results and collaboration degree.4. With the support of IGA and UTI frame already constructed, a citing-based innovation aiding technical model for CIGU participants is proposed, which provides technical support for user’s citing through two models:island model and cell model. A web-based CIGU mechanism is designed, with a detailed description to its aiding mechanisms to individual user, group users and the requirement’s demanders.5. A UTI protosystem was programmed with IGA theory on Solidworks platform, on which user and aiding technique’s combination in product innovation are proved feasible.Conclusive remarks are given for the thesis, with a perspective to further research work.
