一种面向产品规划过程的组合质量屋

针对现代产品设计规划过程中对规划信息的集成性、准确性和完备性的要求,提出了一种面向产品规划过程的组合质量屋,并给出了构建组合质量屋的过程和方法.该组合质量屋包括用户需求质量屋、产品技术特性质量屋和综合质量屋.在构建组合质量屋的过程中,采用网络分析法确定产品技术特性的相对重要度,该方法能综合考虑用户需求间、产品技术特性间以及用户需求层和产品技术特性层之间的相互协作和相互冲突的关系,使得规划结果更加准确可靠.此外,还综合考虑了产品全生命周期各阶段定性和定量约束对规划结果的影响.最后,通过实例研究了运用组合质量屋进行产品规划的步骤和方法,并验证了其有效性. 

Combined house of quality oriented product planning

Product planning requires accurate and integrated planning information. A combined house of quality (CHOQ) oriented product planning was presented. The CHOQ consists of quality house of customer requirements (CRs), quality house of product technical characteristics (PTCs) and complex house of quality. The methodology of setting up the CHOQ was put forward. The analytic network process (ANP) method was employed to weight based on the important levels of CRs and PTCs, which considered the interrelationships among the CRs and PTCs. It makes the result of product planning more accurate. The proposed analytic procedure took into account qualitative constraints (feasibility, resource utilization ratio, etc) and quantitative constraints (cost, time to market, etc) in product life cycle. A case was studied by using CHOQ to fulfill product planning.
