“…The platform model should host adaptable solutions to enable efficient customisation at a later stage. In order for companies to build an ability to create such platforms, it is important to acknowledge that changes will occur throughout the development and that a setbased (SB) approach should be applied to create the adaptability to respond to the change (Raudberget et al 2015). An SB approach focuses on defining and narrowing design spaces in which requirements can be allowed to vary.…”

“…The platform team also deals with the effect of change propagation on the platform. One way to do this is to model the dependencies between functionally organized design solutions (Claesson 2006) in a modular architecture and conduct change propagation analysis of the resulting design structure matrices (Raudberget et al 2015), which enable early design phase assessment of risk and robustness of product architectures. This leads to three types of components:…”

As products are being developed over time and across organisations, the risk for unintended accumulation and mis-conception of margins allocated may occur. Accumulation of margins can result in over design, but also add risk due to under allocation. This paper describes the different terminology used in one organisation and shows the different roles margins play across the design process and in particular the how margins are a critical but often overlooked aspect of product platform design. The research was conducted in close collaboration with a truck manufacturer between 2013 and 2018. The objective was to gain understanding of the current use of margins, and associated concepts evolve along the product life cycle, across organisation and product platform representations. It was found that margins already play an important role throughout the entire design process; however, it is not recognised as a unified concept which is clearly communicated and tracked throughout the design process. Rather different stakeholders have different notions of margins and do not disclose the rationale behind adding margins or the amount that they have added. Margins also enabled designers to avoid design changes as existing components and systems can accommodate new requirements and thereby saving significant design time.

“…Ward et al (1995) and Sobek et al (1999) argued that SBD was a key to Toyota's and TPDS success. Raudberget (2010) and Raudberget et al (2015) investigated how SBD can be implemented in existing product development companies through industrial case studies, while Mebane et al (2011) applied the SBD approach to the design of a Ship to Shore Connector.…”

ADOPT: An augmented set-based design framework with optimisation

During the early stages of any system design, a thorough exploration of the design space can prove to be challenging and computationally expensive. The challenges are further exacerbated when dealing with complex systems, such as an aircraft, due to the high dimensionality of their design space. Arising from the Toyota Product Development System, set-based design allows parallel evaluation of multiple alternative configurations in the early design stages. At the same time, optimisation methods can be employed at later stages to fine-tune the engineering characteristics of design variants. Presented in this paper, is the Augmented set-based Design and OPTimisation (ADOPT) Framework that introduces a novel methodology for integrating the two areas. This allows for a thorough design-space exploration while ensuring the optimality of the selected designs. The framework has been developed using a process-independent and tool-agnostic approach so that it can be applied to the design process of varying kinds of systems. To demonstrate the implementation and potential benefits, the framework has been applied to the design of a generic aircraft fuel system. The results from the case study and the framework itself are discussed, with a number of areas for further development and future work being identified and presented.
