About Linked Design
The central goal of LinkedDesign is to develop the Linked Engineering and Manufacturing Platform LEAP that enables the context-driven and collaborative access to data, information and knowledge from both the engineering and the manufacturing world. As pointed out in Objective 1, relevant information are scattered in different formats and locations. By using LEAP, engineers will be able to access and integrate (currently disconnected) information sources in a convenient way. While the engineering phase is mainly documented in unstructured information sources, the data management within manufacturing processes is rather structured (see Table 1).
|Unstructured Information Sources||Structured Information Sources|
|Design illustrations and images||ERP, CRM, PLM, MES Systems, etc.|
|Technical component descriptions||Business Process Models|
|Material specifications and reports||(Public) Data Services|
|Emails and other communications logs||Sensor Data, KPIs|
|Blogs, Product Reviews, News||Customes Ratings|
To enable the seamless integration of both aspects, the Data Integration of LEAP will apply novel web-scaleobject matching algorithms to de-duplicate multiple logic representations of single real-world objects. Forexample, the Data Integration can find and link references to one specific product distributed over a PLMdatabase, the CAD-file defining the structural product design, a marketing presentation on that product, theproduct-announcement on the enterprise web page and customer ratings in a web forum. Further, object and
schema matching strategies will be used to identify relations between distinct objects as input for the creationof the LinkedDesign Knowledge Network. While the LinkedDesign ontology will define the unified domainschema of this knowledge network, schema matching algorithms will be used to automatically map andintegrate local data sources to this (global) schema, such that the LinkedDesign Knowledge Network willserve as single access point for all LEAP components and users.
While developments in the fields of data integration and knowledge network are domain-independent and can be applied to arbitrary application scenarios, the further LEAP components present manufacturing and engineering specific functionality. The Knowledge Exploitation will be developed as a flexible data analysis framework, where domain and/or application specific analytic bundles can be deployed. LinkedDesign will provide decision support bundles for the optimal design of manufacturing processes and products as well as a bundle which enables the sentiment analysis to mine customer opinions in relation to product specifications and design decisions.
The Automated Design module extends the current approach of knowledge-based engineering to provide a seamless system & workflow integration (see Objective 4). First, it enables the automated formulation and extraction of parameters, rules and constraints on optimal products and process design from the Linked Design Knowledge Network. Second, the developed rule interchange format will serve as interface specification to transfer the extracted design knowledge into existing engineering and manufacturing systems and workflows. For example, based on manufacturing experiences in welding crosspieces, the engineer‘s CAD tool presents optimal angle designs that provide good stability.
To achieve a flexible and extendable platform solution, we will define the generic Linked Design interface―iLEAP‖ that enables the connectivity to arbitrary data source systems and applications as well as data consuming components. Such consuming components range from the Linked Design Front-end that provides context-driven data access as well as tools for the collaborative engineering (see Objective 2 & 3) to existing manufacturing or CAx systems (supported by the Automated Design).
