In 1999, Fred Brooks, virtual reality pioneer and Professor of Computer Science at the University of North Carolina at Chapel Hill, published a seminal paper describing the current state of virtual reality (VR) technologies and applications (Brooks in IEEE Comput Graph Appl 19(6):16, 1999). Through his extensive survey of industry, Brooks concluded that virtual reality had finally arrived and "barely works". His report included a variety of industries which leveraged these technologies to suppor...

The scientific and industrial communities have begun investigating the possibility of making product recovery economically viable. Disassembly sequence planning may be used to make end-of-life product take-back processes more cost effective. Much of the research involving disassembly sequence planning relies on mathematical optimization models. These models often require input data that is unavailable or can only be approximated with high uncertainty. In addition, there are few mathematical mode...

The problem this paper addresses is the tension between descriptive and normative approaches to design theory and methodology. Descriptive approaches typically seek to document, formalize and/or automate existing ad hoc design methods, towards the goal of making current best practices available to all. In contrast, normative approaches attempt to improve upon existing design practices, towards a new method for how design should be done. Both approaches have strengths and weaknesses. This paper s...

Previous research has consistently cited the importance of a usable interface in the successful adoption of the electronic health record (EHR). Among the most time intensive EHR activities is Computerized Physician Order Entry (CPOE) a method of creating and modifying orders through an electronic interface. The Marshfield Clinic, a non-profit, regional health care organization in Wisconsin, is in the process of implementing a new CPOE system. As a part of early evaluation, cognitive and behavior...

With the goal of making product recovery economically viable, disassembly sequence planning and evaluation can be used to influence product design features early in the product design process. Several researchers have investigated using optimization methods to determine disassembly sequences. One of the difficulties with using this approach is that because of the unique aspects of product disassembly at the end of life, input parameters for the optimization algorithms are commonly unavailable or...
