A knowledge-based master model approach exemplified with jet engine structural design
2017
Successful product development requires the consideration of multiple engineering disciplines and the quantification of tradeoffs among conflicting objectives from the very early design phases. The single-largest challenge to do so is the lack of detailed design information. A possible remedy of this issue is knowledge-based engineering. This paper presents a knowledge-based master model approach that enables the management of concurrent design and analysis models within different engineering disciplines in relation to the same governing product definition. The approach is exemplified on an early phase structural design of a turbo-fan jet engine. The model allows geometric-, structural mech…
Presenting a Multi-level Superstructure Optimization Approach for Mechatronic System Design
2010
Synergism and integration in the design process is what sets apart a Mechatronic System from a traditional, multidisciplinary system. However the typical design approach has been to divide the design problem into sub problems for each technology area (mechanics, electronics and control) and describe the interface between the technologies, whereas the lack of well-established, systematic engineering methods to form the basic set-off in analysis and design of complete mechatronic systems has been obvious. The focus of the current paper is therefore to present an integrated design approach for mechatronic system design, utilizing a multi-level superstructure optimization based approach. Finall…
A Design Theory for Secure Information Systems Design Methods
2006
Many alternative methods for designing secure information systems (SIS) have been proposed to ensure system security. However, within all the literature on SIS methods, there exists little theoretically grounded work that addresses the fundamental requirements and goals of SIS design. This paper first uses design theory to develop a SIS design theory framework that defines six requirements for SIS design methods, and second, shows how known SIS design methods fail to satisfy these requirements. Third, the paper describes a SIS design method that does address these requirements and reports two empirical studies that demonstrate the validity of the proposed framework. peerReviewed
Beyond robust design: an example of synergy between statistics and advanced engineering design
2002
Higher efficiency and effectiveness of Research & Development phases can be attained using advanced statistical methodologies. In this work statistical methodologies are combined with a deterministic approach to engineering design. In order to show the potentiality of such integration, a simple but effective example is presented. It concerns the problem of optimising the performance of a paper helicopter. The desgin of this simple device is not new in quality engineering literature and has been mainly used for educational purposes. Taking full advantage of fundamental engineering knowledge, an aerodynamic model is originally formulated in order to describe the fligh of the helicopter. S…
