【摘要】 本文认为产品寿命周期定义中应增加一个市场开拓阶段 ,认为产品全寿命周期成本应当包含生产成本、品牌成本和使用成本三大主要部分。利用质量损失回收提出基于成本的公差稳健设计原则 ,然后应用Matlab工具求解公差设计模型 ,设计结果具有稳健性和简便性更多还原

【Abstract】 A supplement of adding market stage to product life cycle is proposed. The cost in product all-life-cycle should mainly include three parts of product cost, customer cost and band cost. A cost principle of robust tolerance design is given according to QLF. The tolerance model is solved with Matlab. Results are easy to get and robust to design.更多还原
