Conference paper (peer-reviewed)abstract
- Manufactures, developing products, need to adapt and improve their practices taking advantage of technology advancements and simultaneously develop products and solutions to fit a new world. This paper discusses how societal and technological trends drive the need for change and evolution in what is called Systems Engineering Design (SED), indicating a systems view on engineering design. Through an analysis and selected examples it is argued that SED capabilities need to better address the width and complexity of design problem, takes advantages of increased computational power and sensing technologies to master future challenges. An important factor for successful deployment and change in industrial context, is the need for interactive and visual AIDS and easily accessible support methods. This can pave the way also for advanced SED support.

Journal article (peer-reviewed)abstract
- There is a trend toward increased customization of goods to satisfy a wide range of customers using product platforms. However, there is an erroneous notion that product platforms can only be used to provide economic viability in production thanks to the reuse of physical components among a family of products. Yet, this is a limited perception of the potential of a product platform. In this article, an object-oriented approach to support the development of product platforms is proposed to increase efficiency through reuse and flexibility of designs among a family of products. Two modes of the platform development process are addressed: platform preparation and platform execution. Platform preparation prescribes the methods needed to model platform objects, using enhanced function-means models and set-based concurrent engineering processes. During the platform execution process, sets of design alternatives can be configured concurrently throughout the conceptual, system, and detailed phases of the platform development. Three cases illustrate how the same approach may be used in different design scenarios: design space exploration and extension, supply-chain collaboration, and configure-to-order. The approach supports system architects and design engineers in making design decisions that propel the platform development work by enabling analysis in stages where designs are immature and evaluating the goodness of the alternatives early. Ultimately, product platforms can be efficiently developed for modularity and scalability to find feasible product variants and meet the needs of a multitude of customers.

Assessing System Maturity of Interacting Product and Manufacturing Alternatives Before Early Technology Commitment
- 2015

-
Conference paper (peer-reviewed)abstract
- This paper presents a new way to support early assessment of interacting product and manufacturing technologies based on system maturity. This approach is illustrated by an example from the aerospace industry, where alternative technologies are introduced in an existing product and manufacturing systems platform. By assessing the system maturity of interacting technologies, alternative solutions can be eliminated before early technology commitment. This is beneficial for 1) clarifying the company’s status regarding capability and maturity, 2) eliminating immature technologies within a certain capability bandwidth, and 3) prioritizing advanced technology development initiatives with respect to the risk of implementing a manufacturing technology to interact with a product technology. It may also enable reduction in design rework and manufacturing rework that comes with failed maturity matching of product systems and manufacturing systems, thus possible reduction in lead-time and cost could be met.

Accommodating Emerging Technologies in Existing Product Platforms

Conference paper (peer-reviewed)abstract
- For many companies, proficiency in introducing new technologies is central to their business. For instance, for suppliers in the aerospace industry, having extensive knowledge about a specific technology can be crucial for getting to take part in the next airplane project. However, when new technologies emerge as a result of advanced engineering, they are often hard to implement in product platforms. The fragile nature of a working platform originates from the complex relationships between subsystems and variants. Introducing a new technology into the already fine-tuned platform may affect the performance of the platform negatively, or generate a too large development effort to handle. This may lead to reluctance towards introduction of new promising technologies, which in the long run may result in technologies being discarded as infeasible or being introduced much later than necessary. To be able to assess the impact of a technology and safely accommodate it in an existing platform architecture, it needs to be modeled appropriately. Current models of technologies do not describe them in relation to the architecture they are to be implemented in. Further, the common platform architecture models describe change scenarios from a top-down perspective. Technology introduction would require changing the platform from a bottom-up perspective. This paper suggests an approach to accommodate introduction of emerging technologies into a product platform by means of:- Modeling the technologies as systems in a shared model. - Using trade-off curves to describe the bandwidth of technologies.- Introducing a method for changing a present product platform to incorporate new technologiesThe method addresses a number of different factors regarding the new technology, e.g. its maturity level, in order to assess the appropriate course of action to safely use the technology in the existing platform. The approach is illustrated using a case from the aerospace industry covering the implementation of water-cooling technology as a means to increase the performance of a jet engine component.

Conference paper (peer-reviewed)abstract
- The purpose of this work is to develop a new design methodology for product platforms that combines Enhanced Function-Means Modelling and Set-BasedConcurrent Engineering. The methodology presents new ways to narrow down the design space, which is increasingly important when several alternative designs are generated in Set-Based Concurrent Engineering. The result is theArchitectural Option Chart that uses functional couplings between functional requirements and design solutions to eliminate unfeasible platform members.

Modelling and assessing platform architectures in pre-embodiment phases through set-based evaluation and change propagation
- 2015
-
In: Journal of Aerospace Operations. - : IOS Press. - 2211-002X. ; 3, s. 203-221
-
Journal article (peer-reviewed)abstract
- The establishment of a platform architecture is a critical task but there is no methodological support for this in the firstphases of development. There are several approaches for evaluating designs and architectures when an initial design is present,however, not for the phases foregoing the embodiment of ideas into concepts. This paper fills this void by introducing a newdesign methodology for modelling, assessing and narrowing down the architectural design space. It allows exploration of morealternatives in the earliest phases of development, which ultimately may produce better designs. The result is a design space of amanageable and desirable size for subsequent embodiment and detailed design with traditional engineering tools. The advantageis that feasibility of the candidate platforms have been established to a high degree of certainty. The approach is illustrated witha case of redesign showing how a manufacturer of parts for a jet engine can use the methodology to model and assess platformconcepts in the earliest phase of development.

Supporting design platforms by identifying flexible modules
- 2017
-
In: Proceedings of the International Conference on Engineering Design, ICED. - : The Design Society. - 2220-4334 .- 2220-4342. ; 3:DS87-3, s. 191-200, s. 191-200

Conference paper (peer-reviewed)abstract
- One way for firms to stay competitive is to adapt a platform approach. In product platforms, modules are used as exchangeable design blocks to create a variety in product performance. This is a proven way to get advantages of scale in production by reusing physical parts and investments in manufacturing. To ensure exchangeability between modules, interfaces between modules must be well defined. Hence, from this point of view, there is no such thing as flexible modules. In this research, flexibility refers to the idea of identifying strategic portions of the platform where flexibility is needed and to create the modular division in a way that the assigned modules are de-coupled in theses areas. The presented approach shows how the Design platform concept can be extended by the introduction of flexible modules. These support the Design Platforms by allowing areas of strategic importance to be more flexible and thereby enable room for uncertainties such as fluctuating requirements and future technical development.

In: Proceedings of the DESIGN 2016 14th International Design Conference.
-
Conference paper (peer-reviewed)abstract
- A simplified variant of Set-Based Design (SBD) was created and combined with creative methods such as the 6-3-5 method and the gallery method. This made it easy to introduce in one day, which has been verified by tests in industrial firms . In total 45 have experienced designers tested the method on real mechanical design problems.The method was perceived easy to understand and well received by designers. The introduction of it was less cumbersome compared to the full version of SBD. The conclusion is that the developed method makes it easier to introduce parts of SBD with good results.
