快速成形制造网络化服务系统关键技术

阐述快速成形制造(RP&M)技术中采用分布式组件结构所搭建的网络化服务集成系统的体系结构，并按照各组件所具有的特点对系统进行功能设计。建立包含目标层、准则层及方案层的RP&M工艺决策的指标体系，提出一种基于专家系统和模糊综合评判的RP&M工艺选择的新方法，构建RP&M制造工艺选择的决策支持系统。对RP&M协同制造的过程规划进行研究，采用时间尺度原则确立各种RP&M工艺监控点，为过程管理与监控提供理论依据。实际开发的网络化服务系统经应用表明，可以方便、快捷地支持企业新产品远程开发。

KEY TECHNIQUE OF RP&M NETWORKED SERVICE SYSTEM

The structure of the networked integrated service system established on the basis of distributed component structure is expounded, and corresponding functional modules are designed according to each component feature. An index system of RP&M process decision including goal layer, criterion layer and scheme layer is proposed. A new method for RP&M process selection based on expert system and fuzzy synthesis evaluation is presented and the support system for RP&M manufacture process selection is set up. Based on the analysis of process planning of RP&M collaborative manufacture, different types of RP&M process monitoring points are determined according to the time scale principle,which provides the theoretical basis for the process management and monitoring. The implementation of the networked service system verifies its capacity of supporting enterprises with the convenient and rapid remote development of new products.
