工程特性最终重要度的确定是质量屋构建过程中的一个关键步骤.为了以一种经济的方式实现工程特性表现的改进目标,提出基于平衡记分卡的工程特性最终重要度确定方法.在该方法中,根据工程特性表现的竞争性评价,建立一个基于竞争性评价的工程特性重要度确定的优化模型,并通过拉格朗日函数的构造求解此模型;通过平衡记分卡、比例标度法和层次分析法的集成,确定实现工程特性表现的改进目标的重要度;基于工程特性的初始重要度、基于竞争性评价的工程特性重要度和实现工程特性表现的改进目标的重要度的合成,确定工程特性的最终重要度.以某企业双缸洗衣机的产品设计为实例,说明方法的应用.

Determining the final importance ratings of engineering characteristics (ECs) is a crucial step of building house of quality (HOQ). For achieving the improvement goals of performances of ECs in an effective way, a balanced-card-based methodology for determining the final importance ratings of ECs is proposed. In this method, on the basis of the competitive evaluations of performances of ECs, a model for determining the competitive-evaluation-based importance ratings of ECs is built, and this model is resolved by using Lagrange function. Based on the integration of balanced scorecard (BSC), analytical hierarchy process and scale method, the importance rating of achieving the improvement target of performances (ITOP) of every EC is determined. Based on a combination of the initial importance rating, the competitive-evaluation-based importance rating, and the importance rating of achieving the ITOP of every EC, the final importance ratings of ECs are determined. A case study of product development of washing machine in a corporation is provided to illustrate the application of the proposed method.
