A Meta-Model for Knowledge Representation Integrating Maturity for Decision Making in Engineering Design

Abstract

Abstract. Computer Aided Design (CAD) and Computer Aided Engineering (CAE) models are often used during product design. Various interactions between the different models must be managed in a PLM approach for the designed system to be robust and in accordance with defined specifications. To effectively manage engineering changes on the system definition, the dependencies between the different models must be known and managed in a PLM system. A lot of data are exchanged in collaborative design and different problems must be managed in terms of data consistency. We propose a metamodel for knowledge representation integrating maturity concept to support decision making in preliminary collaborative design. A literature survey about existing knowledge models is done before presenting the proposed meta-model of knowledge.

The service task of automotive troubleshooting process in collaborative environment using knowledge support approach

“…They are produced and imported in accordance with the SEs’ perspective. However, this framework of IEs may not reveal the domain engineers’ perspective; (2) the contradiction from members can be detected by KCP, but it is not capable of managing decision making 54,55 ; (3) the collaborative activities are conducted by one member who examine the consistence among IEs. It is efficient for verification but inappropriate for synchronous cooperation.…”

A proposed framework of sustainable self-evaluation maturity within companies: an exploratory study

“…Some departments or sectors within the company may maturate these ideas quicker than others. As a consequence, the level of sustainable maturity may vary from one department to another and also at the different levels of the organization (strategic, tactical and operational) as well as among their personnel [21,22].…”
