Metaheuristics in recent years has proven its effectiveness; however, robust algorithms that can solve real-world problems are always needed. In this paper, we suggest the first extended version of recently introduced gaining–sharing knowledge optimization (GSK) algorithm, named multiobjective (MOGSK), to deal with (MOPs). MOGSK employs an external archive population store nondominated solution...

Knowledge sharing can be seen as a social dilemma. Mutual knowledge sharing can lead to a benefit for all the participants. However, establishing voluntary knowledge sharing can be difficult because each member benefits from the knowledge offered by others but gains little from the own contribution. Knowledge markets could overcome this problem. To analyze knowledge markets we designed and impl...

The Answer Garden supports knowledge sharing in two intertwined ways: by making relevant information retrievable and by mediating access to people with knowledge. We present a case study in which the Answer Garden approach was applied to encourage knowledge sharing in maintenance engineering of a steel mill. The results show that the sheer amount of drawings and the long history of changing cla...

Engineering design is a complex activity, relying heavily on know-how gained from personal experience. Competitive pressures and new technology are making further demands on the skills and experience of designers, as effective knowledge reuse in design is seen as increasingly vital, and the work of design teams is often a collaborative and distributed activity. University students with a thorou...

Ontologies A second way for modularization is to make ontologies that define abstract concepts. These abstract abstract concepts can be used to define more specific concepts in different domains. An example of abstract concepts are taxonomies. A taxonomy is a structured overview of classes, subclasses and instances. Taxonomies can not only be found in biology, but also in engineering domains. C...

In the engineering design, engineers have been suffering from a difficulty in sharing conceptual engineering knowledge about functionality representing design rationale because of the lack of rich common vocabulary for functionality. In order to promote sharing of such knowledge, we have developed an ontological framework for its modeling including layered ontologies, which provides rich concep...

Due to the increasing complexity of technical products and the decrease in product development time (“time to market”) the urgent need for the optimization of cross-skill engineering collaboration demands short-term solutions. In this paper we will therefore introduce an approach to federate the established engineering tools and processes on the basis of commonly shared engineering models rathe...

This paper details an integrated methodology to optimise Knowledge reuse and sharing, illustrated with a use case in the aeronautics domain. It uses Ontologies as a central modelling strategy for the Capture of Knowledge from legacy documents via automated means, or directly in systems interfacing with Knowledge workers, via user-defined, web-based forms. The domain ontologies used for Knowledg...

Hybrid knowledge model is suggested as an underlying framework for product development management. It can support such hybrid features as ontologies and rules. Effective collaboration in product development environment depends on sharing and reasoning product information as well as engineering knowledge. Many studies have considered product information and engineering knowledge. However, most p...

In this paper we lay the foundations for exchanging, adapting, and interoperating engineering analysis models ~EAMs!. Our primary foundation is based upon the concept that engineering analysis models are knowledge-based abstractions of physical systems, and therefore knowledge sharing is the key to exchanging, adapting, and interoperating EAMs within or across organizations. To enable robust kn...
