DFM synthesis approach based on product-process interface modelling. Application to the peen forming process.
Engineering design approach are curently CAD-centred design process. Manufacturing information is selected and assessed very late in the design process and above all as a reactive task instead of being proactive to lead the design choices. DFM appraoches are therefore assesment methods that compare several design alternatives and not real design approaches at all. Main added value of this research work concerns the use of a product-process interface model to jointly manage both the product and the manufacturing data in a proactive DFM way. The DFM synthesis approach and the interface model are presented via the description of the DFM software platform

The role of user requirements research in medical device development
Aims and Objectives: This research aims to suggest a concise framework to help in the better
conceptualisation and integration of users in the medical device development (MDD) process. The
current economic, political and social climate concerning the matter of healthcare delivery has
resulted in the emergence of numerous users and user groups for whom the healthcare system has not
previously catered for. These users have created ambiguity for the designers and manufacturers of
medical devices as the boundaries between their needs and requirements have blurred, outdating
current methods of MDD to meet consumer needs.
Research Design and Methodology: The research methodology begins primarily with conducting a
literature search on the theories relating to user requirements and medical device development. The
paper outlines these findings through initially describing users and user involvement and relating
them to medical devices. The cross-disciplinary nature of healthcare influenced the investigation into
multiple disciplines including; IT, Ergonomics â particularly participatory research, Psychology and
Design. These disciplines expose various methods and processes, which are useful to user
requirements research. These methods were analysed for their compatibility, and then used to
construct a conceptual framework for user involvement in MDD.
Results: The research insinuates the true significance of user involvement and hence resulted in the
formation of a conceptual framework to aid user involvement in the MDD process. The framework is
produced by the amalgamation of relevant methods examined across the disciplines, in a
complimentary fashion.
Conclusion: The originality of this research lies in its use of a multidisciplinary approach. Previous
research claiming multi-methods has dealt with combining two disciplines or methods at a time i.e.
Computer supported cooperative work (CSCW) with participatory research (Scandurra et al, 2008)
for the needs analysis of healthcare professionals only. Collaboration across disciplines has also been
investigated (Johnson et al, 2005), but this was for the purpose of redesign rather than initial designs.
This framework can help medical device designers to fully access all user requirements through more
extensive collaboration right at the start. It reduces the risk of high costs involved in device rejection,
usually associated with belated recognition of user needs in the design cycle

Behaviour change at work: Empowering energy efficiency in the workplace through user-centred design
Copyright @ 2011 University of California eScholarship RepositoryCO2 emissions from non-domestic buildings - primarily workplaces - make up 18 percent of the UK's carbon footprint. A combination of technology advances and behavioural changes have the potential to make significant impact, but interventions have often been planned in ways which do not take into account the needs, levels of understanding and everyday behavioural contexts of building users - and hence do not achieve the hoped-for success.This paper provides a brief introduction to the Empower project, a current industrial-academic collaboration in the UK which is applying methods from user-centred design practice to understand diverse users' needs, priorities, mental models of energy and decision-making heuristics - as well as the affordances available to them - in a number of office buildings. We are developing and trialling a set of low-cost, simple software interventions tailored to multiple user groups with different degrees of agency over their energy use, which seek to influence more energy efficient behaviour at work in areas such as HVAC, lighting and equipment use. The project comprises an ethnographic research phase, a participatory design programme involving building users in the design of interventions, and iterative trials in a large office building in central London

Generative feature-based design-by-constraints as a means of integration within the manufacturing industry
The article examines the development of computer aids within manufacturing industry and proposes an alternative approach to the way we design and the designer's role within manufacturing. A feature-based generative design-by-constraints approach is applied, which requires the designer to specify solutions in terms of manufacturing data, which is captured by means of an interactive simulation of machining processes, in which the constraints of equipment, materials and tools are displayed to the designer. The effect of this approach on the integration of all areas within a manufacturing environment is explored, as is the simultaneous design nature of this approach
Why, what, and how? case study on law, risk, and decision making as necessary themes in built environment teaching
The paper considers (and defends) the necessity of including legal studies as a core part of built environment undergraduate and postgraduate curricula. The writer reflects upon his own experience as a lawyer working alongside and advising built environment professionals in complex land remediation and site safety management situations in the United Kingdom and explains how themes of liability, risk, and decision making can be integrated into a practical simulation in order to underpin more traditional lecture-based law teaching. Through reflection upon the writer's experiments with simulation-based teaching, the paper suggests some innovations that may better orientate law teaching to engage these themes and, thereby, enhance the relevance of law studies to the future needs of built environment professionals in practice.</p
Coordination approaches and systems - part I : a strategic perspective
This is the first part of a two-part paper presenting a fundamental review and summary of research of design coordination and cooperation technologies. The theme of this review is aimed at the research conducted within the decision management aspect of design coordination. The focus is therefore on the strategies involved in making decisions and how these strategies are used to satisfy design requirements. The paper reviews research within collaborative and coordinated design, project and workflow management, and, task and organization models. The research reviewed has attempted to identify fundamental coordination mechanisms from different domains, however it is concluded that domain independent mechanisms need to be augmented with domain specific mechanisms to facilitate coordination. Part II is a review of design coordination from an operational perspective
A proposed psychological model of driving automation
This paper considers psychological variables pertinent to driver automation. It is anticipated that driving with automated systems is likely to have a major impact on the drivers and a multiplicity of factors needs to be taken into account. A systems analysis of the driver, vehicle and automation served as the basis for eliciting psychological factors. The main variables to be considered were: feed-back, locus of control, mental workload, driver stress, situational awareness and mental representations. It is expected that anticipating the effects on the driver brought about by vehicle automation could lead to improved design strategies. Based on research evidence in the literature, the psychological factors were assembled into a model for further investigation
