【摘要】 从全面系统的角度来考虑软件复用活动,将软件复用技术分为需求复用、设计复用和组件复用等三个层次,提出了基于软件复用的层次化模具PDM系统开发模型,为软件复用的开发活动提供了理论基础和方法指导,并且依据该模型开发了可复用模具PDM系统。更多还原

【Abstract】 This paper describes the activity of software reuse from the overall and systemic views, and divides the software reuse technique into three levels: requirement reuse, design reuse and component reuse. The hierarchy mould PDM system developing model based on software reuse is presented to give the theory foundation and method guide for mould PDM system based on software reuse. According to the model, the paper develops a reusable mould PDM system.更多还原
