【摘要】 为了向产品生命周期设计提供寿命信息,在基于特征的产品全生命周期设计集成信息模型的基础上,提出利用灰色GM(1,1)模型对少量已有同类产品的寿命数据进行预测,扩充样本量,由灰色关联度分析得出其最符合的分布类型,由此预测与产品生命周期设计相关的寿命指标值。同时,在VC++6.0环境下,开发了产品寿命预测模块,并给出了应用实例。更多还原

【Abstract】 In order to provide life cycle information for the products whole life cycle design,based on feature-based products whole life cycle design integrated information model,prediction was suggested to carry out on few existing similar products for life cycle data by application of Gray Model(GM),and to enlarge sample volumes so as to get most matching distribution type through analysis of gray association degree.Hence life cycle index associated with products whole life cycle design was predicted.Finally,the prediction module of life cycle was developed by VC++6.0,and the application example was also presented.更多还原
