“…KNOMAD as a methodology laid emphasis on activity diagrams for processes and representation of multidisciplinary knowledge including design and manufacturing (Verhagen et al, 2012). MOKA (Skarka, 2007) as a methodology was initiated for larger applications. It encapsulated both product and process based modelling.…”

Knowledge based engineering (KBE) as a design method helps formulate a comprehensive knowledge base as a virtual prototype which includes design intent, requirements, rationale, and logic along with geometric information, which can then be utilised for representing the product design process, and to achieve complex design automation. One of the identified shortcomings in the field of design process automation using KBE as a holistic approach is a suitable neutral representation technique of a process model with well-defined syntax, axioms, and semantics for it to be shared across multiple platforms and to enable interoperability. To achieve design process automation, two steps are very important. First, a modelling method should be able to informally capture all critical aspects of a process to enable design automation. Second, the informal model should be able to be mapped onto a formal representation technique in a system, which will then enable automation by running a query through this representation. This paper discusses all the critical aspects in the form of design decomposition features and narrows down informal modelling approaches based on the criteria formulated for design automation from the literature. Formal representation techniques are discussed with the help of an example to ensure correct mapping of the informal model to a formal representation. The next steps of this research would be recommendation of the formal representation techniques of the informal model based on the discussion in this paper and for future work that will enable process automation.

“…Creating the initial KBS is time consuming and the user needs to have some knowledge of the system in case of modifying it; however, once it is built there are numerous advantages of it and it could help the user build the necessary system faster and in less time. The Figure 2.1 [21] shows that by adopting KBE the time taken for the routine tasks can be minimized. …”

With the ever growing complexity of aircrafts, new tools and eventually methods to use these tools are needed in aircraft conceptual design. To reduce the development cost, an enhancement in the conceptual design is needed.This thesis presents a knowledge-based aircraft geometry design tool RAPID and the methodology applied in realizing the design. The parameters used to create a geometry need to be exchange between different tools. This is achieved by using a centralized database or onedata concept. One-database will enable creating a less number of cross connections between different tools to exchange data with one another. Different types of aircraft configurations can be obtained with less effort. As RAPID is developed based on relational design, any changes made to the geometric model will update automatically. The geometry model is carefully defined to carry over to the preliminary design.The validation of RAPID is done by implementing it in different aircraft design courses at Linköping University. In the aircraft project course, RAPID was effectively used and new features were added to the obtained desired design. Knowledge-base is used to realize the design performance for the geometry with an integrated database approach for a multidisciplinary aircraft conceptual design.

“…They proposed the enrichment of the MOKA objects, by including the concepts of resource, to consider tools and machines used in manufacturing processes, and function, to define design reasoning activities. Skarka (2007) implemented MOKA classes into Protege, used as repository of product knowledge, and used a commercial CAD system (CATIA v5) to create a KBA application to automate the product geometrical design.…”

Commercial computer-aided design systems support the geometric definition of product, but they lack utilities to support initial design stages. Typical tasks such as customer need capture, functional requirement formalization, or design parameter definition are conducted in applications that, for instance, support "quality function deployment" and "failure modes and effects analysis" techniques. Such applications are noninteroperable with the computer-aided design systems, leading to discontinuous design information flows. This study addresses this issue and proposes a method to enhance the integration of design information generated in the early design stages into a commercial computer-aided design system. To demonstrate the feasibility of the approach adopted, a prototype application was developed and two case studies were executed.
