Use of Ontological Classes in the Exploration of User Needs

Abstract:

This paper provides a new perspective on the construction and use of ontology in the context of the life cycle of the product. All information related to system-product should be available within the PLM (Product Lifecycle Management) but especially in innovative design phase. Because of the complexity of the information and to increase the effectiveness of the conceptual design the use of ontology is required in a particular domain, the design of machine tools, as a means of representation and classification of knowledge. The ontology is used to define a common vocabulary, explicit, formalized and shared by a community of developers in order to share knowledge and increase the efficiency of the design process. On the other hand, the design process is strongly influenced by the clarity and precision of the analysis of customer needs. To design a product well, design teams needs to know what it is the designing, and what the end-users will expect from it. Quality Function Deployment (QFD) [1] is a systematic approach to design based on a close awareness of customer desires, coupled with the integration of the functional groups. This paper proposes a taxonomy of customer needs in the QFD method and a demonstration from our point of view through an Industrial application.
