基于大数据和粗糙集的产品需求分析方法研究
Research on product demand analysis method based on Big Data and rough set
摘要
Abstract
Traditional product design method has many problems on requirements elicitation,such as unitary method,poor timeless and strong subj ectivity.So a method of product requirements a-nalysis based on Big Data and rough set was put forward.By the web crawler technology,desig-ner could real-time acquire vast and unstructured product requirements in a variety of information carrier.By the Big Data analytic tool and rough set,the types of different semantic user require-ments could be acquired.By the house of quality,product requirements were converted to the corresponding engineering design parameters,thus making sure the direction of product design was right.In addition,taking the“Galaxy S6 Edge”for example,by the Big Data analysis of this mobile phone’s user comments in micro-blogging and Jingdong MALL and the using of user re-quirements calculation method based on rough set,the effectiveness of the proposed method is verified.关键词
