“…Trade studies can be used to create many potential designs quickly through automated software packages such as ModelCenter (http://www.phoenix-int.com) or Advanced Trade Space Visualization (Stump, Lego, Yukish, Simpson, & Donndelinger, 2009) as part of ModelCenter. Trade studies are also used by teams of people to conduct manual trade study sessions (Oberto et al, 2005). Automated trade studies can also be performed by computers using conditions and bounds set by users.…”

“…CDCs often will perform manual trade studies as part of the design process. The most cited example of a CDC is Team-X that is housed in the Project Design Center at the Jet Propulsion Laboratory and develops conceptual spacecraft mission designs (Oberto et al, 2005). In such manually conducted trade studies, subsystem experts often disagree over which tradeable parameters are the most important (NASA, 1995; Ross et al, 2004; Federal Aviation Administration, 2006).…”

2012). Risk attitudes in risk-based design: Considering risk attitude using utility theory in risk-based design. AbstractEngineering risk methods and tools account for and make decisions about risk using an expected-value approach. Psychological research has shown that stakeholders and decision makers hold domain-specific risk attitudes that often vary between individuals and between enterprises. Moreover, certain companies and industries (e.g., the nuclear power industry and aerospace corporations) are very risk-averse whereas other organizations and industrial sectors (e.g., IDEO, located in the innovation and design sector) are risk tolerant and actually thrive by making risky decisions. Engineering risk methods such as failure modes and effects analysis, fault tree analysis, and others are not equipped to help stakeholders make decisions under risk-tolerant or risk-averse decision-making conditions. This article presents a novel method for translating engineering risk data from the expected-value domain into a risk appetite corrected domain using utility functions derived from the psychometric Engineering Domain-Specific Risk-Taking test results under a single-criterion decisionbased design approach. The method is aspirational rather than predictive in nature through the use of a psychometric test rather than lottery methods to generate utility functions. Using this method, decisions can be made based upon risk appetite corrected risk data. We discuss development and application of the method based upon a simplified space mission design in a collaborative design-center environment. The method is shown to change risk-based decisions in certain situations where a risk-averse or risk-tolerant decision maker would likely choose differently than the expected-value approach dictates.

In this paper, the open-source Nanospace framework is presented, dedicated to facilitate concurrent engineering during the preliminary design phase of CubeSats. It allows for direct information exchange between third-party expert software, while allowing transparent data visualization to any team member. It provides a web based GUI, and relies on a database with ACID properties and provides a RESTful API. Nanospace ensures concurrent access to the data, which is relevant when teams are working remotely. Nanospace also provides an intuitive way of visualizing other experts' contributions that can be of high value when looking for internal project understanding and transparency. The paper presents the modular software architecture of Nanospace, as well as design choices and the different options to connect to third-party specialized software and the database.

“…By bringing all the requisite expertise into the same room (experts with their analysis tools and data) and working design issues as a team, concurrent engineering overcame many of the bottlenecks and communication pitfalls of the traditional design approach that relied on a physically distributed team, ad hoc information transfer, action items and periodic status meetings. As a result, it reduced the time and cost for conceptual designs drastically, such that conceptual designs can be completed in a fraction of the previous time and cost -some authors report a reduction in cost by as much as a factor of five [3]. The subsequent rapid adoption of concurrent engineering throughout the aerospace industry and its continued growth attests to its value as a design methodology.…”

“…The distributed sessions that have been conducted to date have had limited bandwidth which will not be sufficient to meet CE needs if distributed sessions become more commonplace. For example, currently the interaction is primarily via telecon, and may have shared displays [3]. Video displays of the other teams can produce low quality images that often hinder communication.…”

Over the past sixteen years, government aerospace agencies and aerospace industry have developed and evolved operational concurrent design teams to create novel spaceflight mission concepts and designs. These capabilities and teams, however, have evolved largely independently. In today's environment of increasingly complex missions with limited budgets it is becoming readily apparent that both implementing organizations and today's concurrent engineering teams will need to interact more often than they have in the past. This will require significant changes in the current state of practice. This paper documents the findings from a concurrent engineering workshop held in August 2010 to identify the key near term improvement areas for concurrent engineering capabilities and challenges to the long-term advancement of concurrent engineering practice. The paper concludes with a discussion of a proposed vision for the evolution of these teams over the next decade 1 .
