A Methodology for Product Family Ontology Development Using Formal Concept Analysis and Web Ontology Language

Abstract

The use of ontologies for information sharing is well documented in the literature, but the lack of a comprehensive and systematic methodology for constructing product ontologies has limited the process of developing ontologies for design artifacts. In this paper we introduce the Product Family Ontology Development Methodology (PFODM), a novel methodology to develop formal product ontologies using the Semantic Web paradigm. Within PFODM, Formal Concept Analysis (FCA) is used first to identify similarities among a finite set of design artifacts based on their properties and then to develop and refine a product family ontology using Web Ontology Language (OWL). A family of seven one-time-use cameras is used to demonstrate the steps of the PFODM to construct such an ontology. The benefit of PFODM lies in providing a systematic and consistent methodology for constructing ontologies to support product family design. The resulting ontologies provide a hierarchical conceptual clustering of related design artifacts, which is particularly advantageous for product family design where parts, processes, and most important, information is intentionally shared and reused to reduce complexity, lead-time, and development costs. Potential uses of the resulting ontologies and FCA representations within product family design are also discussed.

Capitalizing Data, Information and Knowledge on Mechanical Experiments through Ontologies

“…As a matter of fact, providing an effective methodology for creating ontological models is a crucial issue, especially since there is a lack of a general methodology for creating ontologies (Nanda et al, 2006). In various domains, some methodologies for creating ontologies have been developed, like METHONTOLOGY for chemistry applications (Fernandez-Lopez et al, 1999), Toronto Virtual Enterprise (TOVE) with a scenario-based methodology (Gruninger & Fox, 1995) or the On-To-Knowledge methodology (Staab et al, 2001).…”

A Decision Support Ontology for collaborative decision making in engineering design

“…A semantic approach that is receiving great attention is based on ontological knowledge-bases. Recent works with ontologies in engineering design can be roughly divided into three groups: 1) product knowledge support [20,24], 2) design activities [21][22][23][25][26][27], and 3) knowledge retrieval [3,28]. A fundamental limitation of current design support tools is the primary focus on product information and not on the decision process [29].…”

A product design ontology for enhancing shape processing in design workflows

“…Few methodologies tailored to product design have emerged recently; for instance, in (Nanda et al, 2006) a formal methodology has been proposed, which, whilst is well structured, is very targeted towards product families rather than shape processing in product design.…”
