摘要
企业将产品创新设计过程向用户开放,在获得用户海量创新资源及用户真实需求的同时,大量无组织自主个体参与造成的设计过程趋于复杂也逐渐引起重视,亟待研究用户自主参与产品设计过程的动态特性。与已有文献将用户在开放设计过程中提交的方案视作不变常量不同,本文考虑设计过程中用户间的交互导致用户个体方案随时间变化的特征,研究用户个体互动、并促进产品模型迭代完善的动态规律。首先,从微观角度研究基于博弈理论的用户个体互动演化机制;其次,从宏观角度研究参与设计用户组成的复杂网络典型特征。根据理论研究,采用软件仿真方法,研究用户参与产品设计过程动态特性的定性规律,结果表明,开放设计过程中产品模型始终趋于收敛。以煤炭破碎机的用户参与设计为实例,统计设计过程中参与用户个体方案与产品模型的交互迭代演化规律,验证了本文理论模型与仿真结果的正确性。
In order to obtain users'massive innovative resources and real user needs,enterprises open product innovative design process to users.Due to the involvement of a large number of unorganized and autonomous individuals,the dynamic and complex evolution of the design process has gradually attracted attention.Unlike the existing literature,which regarded the user's proposed product solution as a constant,the process of user participation in design was regarded as a dynamic gradient process.Therefore,the user's individual solution and the product model interacted and iterated in the process.Firstly,the typical results of individual interaction of the user were studied.Based on the game theory,the game model was established and its Nash equilibrium was solved.Secondly,the dynamic evolution of user groups was analyzed and its growth process was simulated.The simulation results were compared with the definition of the scale-free network,and the conclusion was drawn that the user group involved in the design was a typical scale-free network.According to the user's individual interaction model and the user group network model,the software simulation was carried out.The coal crusher design project was used as a case study to verify the correctness of the theoretical model and simulation results.The conclusion that the product model tended to converge in different communication environments was obtained.This conclusion provided a theoretical basis for the application of a large number of users to participate in the design.According to the discrete point simulation and the surface fit,the convergence speed distribution of product solution with user's game income as the argument was obtained.It was concluded that the convergence speed of the overall solution of the product was related to the parameters of the interactive environment,which was more complex and irregular.Therefore,dynamic monitoring was important when users were involved in the product design process.
