基于变化减少方案的变化性及其应用研究

Research on Variety Based on VRP and Its Applications

在变化减少方案(VRP)理论的基础上,研究了变化性的层次模型:参数层、实体层和体系层,并从产品结构变化性和制造结构变化性两个方面分别分析了变化性的内容、形式及其使能技术。提出了产品结构变化性和制造结构变化性集成化的思想,以及实施变化性的策略和方法。针对参数层变化性,提出了一种支持产品结构变化性和制造结构变化性的零件族模型,并通过一个实例进行了验证,结果表明,基于VRP的产品变化性在提供多样化产品的同时,可以有效控制产品成本、缩短产品交货期。

The hierarchical model of variety was studied on the basis of VRP theory, including parameter, entity and architecture tiers. The contents, forms, and its enable technologies of variety were analyzed from two aspects of product structure variety （PSV） and manufacturing structure variety （MSV） respectively. The integration between PSV and MSV was proposed, and the strategy and method to implement variety were researched as well. Then a part family model supporting PSV and MSV was put forward aiming at the variety in parameter tier. Finally, an example was given to verify that principle and system. The results indicate that product variety based on VRP can provide diversity product with efficient cost, and short product delivery date.
