“…The classification was refined until we had reached the smallest classification of influencing factors that accounted for our cases and those we had found in the literature. Afterward, during new projects we have been discussing these factors within a workshop that was conducted on system architecture decision support (Ben Hamida et al, 2015). These discussions suggested refinements and allowed us to partially validate the factors and their impact on the system architecture design process.…”

Abstract:Many of the most fundamental decision about a product are taken during the system architecture design process. However how system architecture is designed in practice is not well understood. This paper draws on several research studies related to system architecture design to develop a categorization of system architecture design processes to support the adaptation design methodologies and tools to specific situations. The paper reviews different definitions of system architecture and comments on the relevance of the different perspectives taken in the literature on system architecture to different types of system architecture. The research highlights the need for further empirical research on system architecture design processes as well as on tools to support the engineers creating the system architecture.

“…Functions translate needs into a physical structure that will meet those needs. Function modelling is the formal way to define and model functions [35]. In plasma-based mass separation for HLRW, the process has five main tasks or stages: waste preparation, waste injection, waste ionization, waste mass separation, and finally, waste collection.…”

Solid spent nuclear fuel from nuclear power plants contains 3.4% fission products (80–160 amu), contributing to a radioactivity level of over 99.8%. On the other hand, liquid high-level radioactive waste (HLRW) from spent fuel reprocessing is composed of 98.9% bulk elements (0–60 amu) with 0.1% radioactivity. A separation mechanism for the mass categories into groups presents unique opportunities for managing HLRW in the long term with a considerable cost reduction. This paper proposes a thermal plasma-based separation system incorporating atmospheric-pressure plasma torches for HLRW mass separation into low-resolution mass groups. Several engineering issues must be addressed, such as waste preparation, waste injection into the plasma, and waste collecting after mass separation. Using the COMSOL Multiphysics simulation, the generic system can be studied using noble gas mass separation, and the mass filter capabilities can be further analyzed. This paper provides the history of plasma-based mass separation. The functional modelling of a thermal plasma mass separation system is proposed under atmospheric pressure. Finally, aspects of mass separation simulation using the noble gases argon and helium inside the plasma mass separation system are studied via COMSOL Multiphysics.

“…Eppinger et al (2012) define system architecture as "the structure of the system, embodied in its elements, their relationships to each other (and to the system's environment), and the principles guiding its design and evolution -that give rise to its functions and behaviours". Relying on these descriptions, Hamida et al (2015) state that the functional architecture represents one facet of the system architecture and links system design intentions to the physical world. For developing a system architecture, Bonjour et al (2009) argue that matrix-based product modelling methods represent the product architecture, product elements and their relationships, shown as a matrix.…”

“…The possible key drivers for the rising complexity, within which we have to design systems for 21st century (Hallissy et al, 2013) were emerged into the following eras including rise of the sustainable development paradigm, the rapid and pervasive information technology, the huge growth in the services economy, and the expansion of economic globalization (see Figure 1.1). Developing the next generation of sustainable technology is not about making things that are faster, bigger and better.…”

A multi-methodology and sustainability-supporting framework for implementation and assessment of a holistic building renovation: Implementation and assessment of a holistic sustainable building renovation

Future building renovation concerns more holistic perspectives related to the sustainability seen in a wider range of objectives/criteria facilitated by the renovation scenarios. Renovation should be a means of improving and developing buildings to meet the needs and challenges of the future and of making homeowners and tenants less vulnerable due to rising energy costs in the future. There is a great potential for reducing energy consumption in existing buildings. However, that does not mean compromising on the quality and architectural values that make the buildings special. Therefore, existing buildings cannot simply be renovated, but must undergo a deep transformation to comply with wider range of objectives/criteria. That includes and addresses the "hard" objectives/criteria (quantitative/measurable criteria such as energy consumption or energy generation) and the "soft" objectives/criteria (qualitative/immeasurable criteria such as spatial quality) in parallel. These objectives both can be achieved, if holistic renovation scenarios are generated each time the buildings are renovated by focus on addressing both the mentioned objectives/criteria. In this framework, the major difference between a deep building renovation and an ordinary one is a commitment to a holistic approach in which objectives/criteria are targeted early in the design stages and subsequently are considered for their interdependence throughout sustainability perspectives.A review of recent research has revealed that the present efforts on sustainable objectives fulfilment in renovation projects are not sufficient. It demonstrates compounding the typical challenges of a sustainable retrofitting from theory to implement stages is lack of an appropriate design methodology. It should take into account retrofitting projects initially in order to interact with the different stakeholders and then to embark on the sustainability objectives/criteria in its full sense. It should assist to identify, manage, and evaluate the holistic objectives among various alternative retrofitting solutions during the early design stages. In this perspective, the present thesis has been developed according to the following objectives: a) It primarily considers building renovation as a complex messy/wicked problem. As such, it gives details on how combinations of methods that are parts of SSM (Soft Systems Methodologies) and MCDM (Multi Criteria Decision Making Methods) are able to cope with its complexity. It consequently develops a methodology, which is entitled Holistic Multi-methodology for Building Renovation -HMSR. The HMSR serve as a means to structure retrofitting problems in accordance with the sustainability in its full sense to support the decision-making and help to develop most appropriate retrofitting scenarios. b) It addresses a new simplified holistic sustainability decision-making support framework, which applies to the structures of the built environment for building renovation projects. The developed framework can be applied during differe...
