摘要: 为解决质量屋的顾客需求信息中所存在的模糊性、不完整、不一致和冗余等问题,提出了基于粗糙集理论的顾客需求分析技术解决方案。该方案以数据仓库和数据挖掘技术为基础,存储、分析并处理已获得的顾客需求初始信息。利用分明矩阵启发式粗糙集约简算法来约简顾客需求信息规则,减少不必要的工程特性改动,降低产品设计与改进的成本和风险。借助J2EE架构与Oracle数据仓库,实现了约简算法,并验证了预期的效果。

Abstract: To solve the problems of fuzziness, imperfection, inconsistency and redundancy in House of Quality′s (HoQ) customer requirements information, the analysis technology of customers' requirements based on rough set theory was presented, which was based on data warehouse and data mining technology. The original customer requirements information was stored, analyzed, processed to be suitable for HoQ in Quality Function Deployment (QFD). Heuristic rough set theory was adopted to simplify customer requirements information rules, reduce unnecessary project identity changes, and lower the cost and risk on product design and product improvement. By using J2EE and Oracle data warehouse, the method was implemented and validated.

Key words: quality function deployment, house of quality, rough set, data mining, data warehouse
