摘要
舰船全寿命敏捷供应链及其信息视图形成与产品全寿命协同设计及其动态联盟组建过程是密切相关的。数据网格(D ata G rid)主要包括数字图书馆技术和数据网格服务技术,它能为敏捷供应链与其它信息系统集成和共享提供技术保障。根据舰船全寿命敏捷供应链信息共享需求,提出了一个多层次交叉的、以两个数据网格服务中心(船舶设计建造和运行维修两个数据网格服务中心)为基础的船舶全寿命动态联盟信息共享结构及基于数据挖掘算法的资源和信息发现流程。在通过数据网格服务获取某设备的维修数据后,应用改进的灰色聚类算法发现故障的规律,这对新产品的改进和开发是很重要的。一个已开发的原型系统实现了两个数据网格服务中心的信息共享并将灰色聚类算法应用于船用泵的故障规律的发现。
To organize the ship life cycle ASC （Agile Supply Chain） and to generate its information views are tightly related to the product life cycle cooperative design and the process of establishing the dynamic alliance. Data grid mainly includes the digital library and data grid service technologies and it can provide the reliable technologies to integrate the ASC and other information systems and to execute information share. The structure of the multi-layers and cross information share in the dynamic alliance for the ship life cycle ASC based on two data grid service centers （for design and shipbuilding as well as for ship operation and maintenance） and the flows of resources and information discovery based on data mining are proposed according to the information share requirements. After obtaining the ship maintenance data through the data grid service, the equipment failure rules are found by an improved grey clustering algorithm. A developed protocol system for the information share is presented and the grey clustering algorithm is used to find main failure rules for ship pumps.
