Abstract Virtual prototyping is the replacement of hardware prototypes by computational prototypes of systems and the processes that they may undergo. The particular domain of investigation is product demanufacture and service. By catching downstream problems early in the design process through the use of virtual prototypes, more environmentally friendly and easily serviceable products should result. The approach to virtual prototyping pursued here is to combine simulation and human interaction with virtual environment technologies, resulting in a Virtual Design Studio. In the Studio, people will simulate demanufacturing and servicing processes on product models, then incorporate the simulation results into design decision making. The Studio will operate on a design studio metaphor, analogous to the desk-top metaphor utilized in Macintosh computers. This paper represents work in progress. The research program undertaken to construct such a Studio is reported and motivated, an initial design studio metaphor is articulated, and current progress is summarized.

This paper re-visits the basic premises of open building: designing for change as well as for stability, including the users in the design decision-making processes, and disentangling the building systems into the levels and allowing replacement; then, addresses the limitations of conventional design media in terms of the capabilities to support these aims. It is discussed that the design media should be predictive, dynamic, and interactive. Virtual prototyping as an enabling technology is reviewed and proposals are made for the future use of this technology for open building design.

A group of faculty at Penn State's Department of Landscape Architecture observed that the traditional master/apprentice model of studio instruction fosters greater student dependence on faculty for decision-making guidance than the faculty considers desirable. They contend that this traditional model promotes a studio dynamic that encourages students to look to the professor for design ideas and wait for faculty approval before making design decisions. The faculty considered this decision-making dependency to be in conflict with the need for students to develop the critical-thinking skills required to address the complex and ill-structured problems that are common in architecture and landscape architecture. In response to their concern this faculty team developed a studio teaching method they termed “independent design decision-making.” They speculated that by transferring the responsibility for design decisions from professor to the student, students could improve their critical thinking and gain confidence in design decision-making. The faculty conceived a set of strategies to implement in a 3rd year team-taught site planning and design studio that presents a range of complex design issues and scales. In collaboration with Penn State's Schreyer Institute for Teaching Excellence, the faculty researchers developed a 2-year comparative study to test this new teaching method in the same design studio with two consecutive student groups-evaluating the strategies implemented in the first year, refining methods, then applying and re-evaluating the results in the next year's class. These new strategies included ways students receive information to inspire their designs (“input strategies”) and ways to receive critique on their design ideas (“feedback strategies”). Two evaluation instruments were chosen to assess this method of studio teaching: 1) the Group Embedded Figures Test (GEFT), and 2) Student Assessment of Learning Gains (SALG). This paper presents this teaching/learning method and reports on the results of the comparative study.

Abstract Most virtual prototypes used within the domain of mechanical engineering are well defined geometric representations loosely linked to analysis packages. By taking a holistic, top-down view of the product introduction process this paper argues that virtual prototypes should be based upon product models that allow for the representation of more than just geometric information. A methodology based upon the reference model for open distributed processing is presented that simplifies the task of deciding what information should be supported. The paper argues that virtual prototypes should use product models that integrate the representation of the geometry, function and behaviour of a product. A case study is presented to show how experimental virtual prototyping software, based on such a product model, can aid the product introduction process.

The study of situations involves asking how people behave in particular environmental settings, often in terms of their individual personality differences. The ecological rationality research program explains people’s behavior in terms of the specific decision-making tools they select and use from their mind’s adaptive toolbox when faced with specific types of environment structure. These two approaches can be integrated to provide a more precise mapping from features of situation structure to decision heuristics used and behavioral outcomes. This chapter presents three examples illustrating research on ecological rationality and its foundations, along with initial directions for incorporating it into an integrated situation theory.

AbstractBiobased production has been promoted as a sustainable alternative to fossil resources. However, controversies over its impact on sustainability highlight societal concerns, value tensions and uncertainties that have not been taken into account during its development. In this work, the consideration of stakeholders’ values in a biorefinery design project is investigated. Value sensitive design (VSD) is a promising approach to the design of technologies with consideration of stakeholders’ values, however, it is not directly applicable for complex systems like biorefineries. Therefore, some elements of VSD, such as the identification of relevant values and their connection to a technology’s features, are brought into biorefinery design practice. Midstream modulation (MM), an approach to promoting the consideration of societal aspects during research and development activities, is applied to promote reflection and value considerations during the design decision making. As result, it is shown that MM interventions during the design process led to new design alternatives in support of stakeholders' values, and allowed to recognize and respond to emerging value tensions within the scope of the project. In this way, the present work shows a novel approach for the technical investigation of VSD, especially for biorefineries. Also, based on this work it is argued that not only reflection, but also flexibility and openness are important for the application of VSD in the context of biorefinery design.
