Information and knowledge management were introduced in the engineering field to help product developers avoid "reinventing the wheel". As PDM and DMS systems manage the whole information about a developed product, no software systems for capturing, managing and analysis of the product development processes are available. This information is usually stored(More)
In this paper we address and discuss the problem of learning graphical models like Bayesian networks using structure learning algorithms. We present a new parameterized structure learning approach. A competing fusion mechanism to aggregate expert knowledge stored in distributed knowledge bases or probability distributions is also described. Experimental(More)
To this day, as a result of increasing PLM penetration and continuously changing company structures, several PLM solutions have evolved over time and now exist in parallel within many companies. Disharmonized PLM solutions can impede productivity and flexibility in cross-division cooperation and company-internal reorganization projects. A lot of companies(More)
The objective of the work presented in this paper is to provide a methodology and tools for distributed PDM environments especially suited for virtual project based cooperation in engineering design. A research project called WebFlex-PDM (Web-enabled Flexible PDM federation) is introduced. This project mainly deals with extensions to existing PDM systems to(More)
This paper describes a specialized PLM approach with operation monitoring and maintenance of the product during its usage based on a condition monitoring method framework. A coupling procedure integrates the PLM meta data model with associated condition monitoring and diagnosis method framework results. Graphical models dealing with a priori information(More)
At present, product lifecycle data is provided, used, and archived only for very specific purposes. Textual data generated in product use can be very comprehensive and contain valuable information beyond its original purpose, e.g. for product development or improvement. This kind of information, however, is not fed back systematically, as its evaluation is(More)
