Integration of machine data in Product-Lifecycle-Management

在产品开发过程中，特定领域的模型和越来越多的工程服务的使用导致了越来越多的主要是异质的和分散的数据集。在产品生命周期的操作阶段，更复杂和更智能的产品也提供了快速增长的数据量，这些数据也存储在异类和分散的数据集中。网络和机器通信方面的努力加强了这一无处不在的进步。不存在对产品和机器数据的全面管理。机器制造商和机器操作员无法通过即时访问一致地共享信息。因此，机器制造商无法接触机器生活。机器操作员无法从产品型号以及最新开发结果和变化中请求信息。这种情况在联网的机器和产品的约束下变得有问题。在这种情况下，一方面，由于单个机器和这种网络物理系统的机器组件之间的动态和基于事件的通信，适当的产品属性和行为很难完全建模。另一方面，尤其是组织上的缺陷阻碍了协调、多方向和可重复的信息交流。产品全生命周期管理的策略需要通过机器数据的集成来增强。产品开发和运营阶段之外的开发工程师、服务技术员、机械和其他行为者或对象获得一个公共数据库。拟议的项目通过集成层管理所谓的现场模型，特别是机器的集成层，为联合信息系统提供了基础。一个锚定的字段映射模式与产品开发和运营阶段的不同数据集的数据结构相关联，适配的过程基于字段模型实现集成层不同用户之间的信息交换。此外，现场事件存储器存储操作阶段的机器特定信息。

During the Product Development Process domain-specific modelsand the increasingly use of Engineering services result in a growingnumber of mainly heterogeneous and scattered datasets. In theOperational Phase of the product life cycle the more complex andsmarter products also provide a rapidly growing volume of date,stored in heterogeneous and scattered datasets, too. Efforts innetworking and machine communication intensify this ubiquitousprogress. A comprehensive management of product and machinedata does not exist. Machine manufacturers and machine operatorsare not able to share information consistently with instant access.Thus, machine manufacturers are out of reach of the machine life.Machine operators cannot request information from the product modelas well as the latest development results and especially changes.This circumstance is becoming problematic within the constraints ofnetworked machines and products. In this context, on the one hand,adequate product properties and behaviour are challenging tocompletely modeled because of the dynamic and event-basedcommunication between individual machines and machinecomponents of such cyber-physical systems. On the other hand, inparticular organizational shortcomings prevent a coordinated,multidirectional and reproducible information exchange. Thestrategies of product lifecycle management need to be enhanced bythe integration of machine data. Development engineers, servicetechnicians, machinery and other actors or objects out of the ProductDevelopment and Operational Phase gain a common database. Theproposed project provides the fundamentals for a federatedinformation system by means of an integration layer that manage a socalled Field Model, especially for machines. An anchored FieldMapping Schema is associated to the data structures of the differentdatasets from the Product Development and Operational Phase.Adapted processes realize the exchange of information betweendifferent users of the integration layer, based on the Field Model. Inaddition, an Field Event Memory store machine-specific information ofthe Operational Phase.
