摘要
群智创新通过网络社区聚集企业外部大规模设计资源参与产品创新设计,成为互联网环境下企业拓展设计能力、解决设计难题、实现转型升级的重要方式.针对群智协同设计活动的复杂性难以定量描述,导致互联网社区中设计活动的发布、推送和动态调整缺乏量化依据等问题,提出一种基于信息熵的群智协同设计活动复杂性度量方法.通过分析互联网社区中群智协同设计过程特点、用户角色和能力特点,从过程复杂性、问题复杂性、可解复杂性3个维度建立群智协同设计活动复杂性度量模型,采用信息熵理论实现复杂性的量化分析;最后以Local Motors社区LM SF-01项目中的悬架设计活动为例,计算该设计活动3个维度的复杂性分别为318.15、477.66、134.46 bit,根据项目特点采用加权的方式得到其统一复杂性为331.76 bit,验证了该复杂性度量模型和方法的可行性和有效性.
Crowd intelligence(CI)innovation has become an important product innovation tool in the environment of Internet as it can amass huge design resources outside the enterprises through online community.It is an important way for enterprises to expand design capabilities,solve design problems,and realize transformation and upgrading.The design activity complexity of crowd intelligence collaborative innovation is difficult to quantitatively describe.As a result,it leads to the absence of a quantitative basis for the release,push,and dynamic adjustment of design activities in the Internet innovation community.To solve these problems,a design activity complexity measurement method based on information entropy theory is put forward.First,the characteristics of the collaborative design process in Internet innovation community,as well as user types and capacity characteristics are analyzed.Second,three dimension including process complexity,problem complexity,and solvability complexity,are proposed to valuate design activities.Then,the quantitative methods are proposed on the basis of information entropy theory.Finally,the suspension design of project LM SF-01 in the Local Motors community is used as an example to calculate its complexity.The complexity in the three dimensions are respectively 318.15,477.66 bit,and 134.46 bit.According to the characteristics of user participation,the weighted complexity of the design activity is 331.76 bit,which validates the effectiveness and feasibility of the complexity measurement model.
