摘要： As CAD models continue to become more critical information sources in the product's lifecycle, it is necessary to develop efficient mechanisms to store, retrieve, and manage larger volumes of increasingly complex data. Because of their unique characteristics, 3D annotations can be used to embed design and manufacturing information directly into a CAD model, which makes models effective vehicles to describe aspects of the geometry or provide additional information that can be connected to a particular geometric element. However, access to this information is often limited, difficult, and even unavailable to external applications. As model complexity and volume of information continue to increase, new and more powerful methods to interrogate these annotations are needed. In this paper, we demonstrate how 3D annotations can be effectively structured and integrated into a Product Lifecycle Management (PLM) system to provide a cohesive view of product-related information in a design environment. We present a strategy to organize and manage annotation information which is stored internally in a CAD model, and make it fully available through the PLM. Our method involves a dual representation of 3D annotations with enhanced data structures that provides shared and easy access to the information. We describe the architecture of a system which includes a software component for the CAD environment and a module that integrates with the PLM server. We validate our approach through a software prototype that uses a parametric modeling application and two commercial PLM packages with distinct data models.

摘要： The aim of Information Lifecycle Management (ILM) is to govern data throughout its lifecycle as efficiently as possible and effectively from technical points of view. A core aspect is the question, where the data should be stored, since different costs and access times are entailed. For this purpose data have to be classified, which presently is either done manually in an elaborate way, or with recourse to only a few data attributes, in particular access frequency. In the context of Data-Warehouse-Systems this article introduces an automated and therefore speedy and cost-effective data classification for ILM. Machine learning techniques, in particular an artificial neural network (multilayer perceptron), a support vector machine and a decision tree approach are compared on an SAP-based real-world data set from the automotive industry. This data classification considers a large number of data attributes and thus attains similar results akin to human experts. In this comparison of machine learning techniques, besides the accuracy of classification, also the types of misclassification that appear, are included, since this is important in ILM.

摘要： In modern, global manufacturing business, value is increasingly created by services related to products rather than the products themselves. In industries related to the built environment, various products installed in the buildings are a major asset for the operators and managers of buildings. Product Lifecycle Management (PLM), managing and exploiting product-related information throughout the lifecycle of the product, has become both a requirement and an important tool for effective service business development. Extensive and interactive PLM requires a universal system for information exchange across the lifecycles of buildings and products. The objective of the study is to define and implement the minimum requirements set by a product- centric information exchange system in an IFC-based product information model, based on use case of managing installed medical equipment in hospital environment. The study comprises a literature analysis and a use case. Late literature was reviewed to analyse developments of intelligence and lifecycle management in products and buildings. It was found that major challenges exist in exchanging lifecycle information between stakeholders and across lifecycle stages. Based on the analysis, it is proposed that using the technologies of building information modelling and a product-centric information exchange system could provide novel solutions to the identified challenges. In the use case, a method was developed for incorporating an open, product-centric PLM information exchange system into the existing IFC standard. It was found that an URI-based, product-centric information exchange system using external databases and product servers satisfies the requirements of effective PLM information exchange. Additionally, it was found that using IFC for product information modelling can effectively support such a system by linking virtual building and product information models into the lifecycle information stored in external servers.

摘要： 模具图纸在整个生命周期内会产生大量的信息,而这些信息大部分是在过程中产生的,行业内普遍重视结果,而忽略了过程信息,造成了后期模具图纸信息查询、检索的阻碍。解析了模具图纸的整个生命周期,分析出模具图纸全生命周期内信息管理存在的问题,依据模具图纸的全生命周期为主线,结合本体的建模技术,开发了模具图纸管理系统。系统能够支持模具、图纸信息的有效检索、查询以及相应文档的生成,实现模具图纸管理的过程化、实时化,有效地提高了模具图纸管理的效率。
